How Much Does It Cost to Build a Garage in NZ? 2026 Auckland Calculator & Guide

Quick answer: Building a new garage in Auckland in 2026 costs roughly $25,000–$40,000 for a single, $40,000–$60,000 for a standard double, and $80,000–$120,000+ for a fully lined garage-and-sleepout combo. Use the calculator below for a personalised estimate, then read on for what actually moves the price.

If you’re pricing a new garage for your Auckland home, the spread you’ll see online is wide — and a lot of it is out of date. The figures we used on this page back in 2020 still surface in search results, but they don’t match what we’re quoting today. Building costs have moved. So have the consent rules — twice in the last eighteen months. And the cheapest option (a kitset) sits at a completely different end of the budget from the most popular one (an attached garage built as part of an extension). Already have a garage you’d rather repurpose? A garage conversion turns existing space into a bedroom, office or rental without the cost of building new.

This page gives you the calculator, the 2026 numbers, and the regulatory picture in one place. For the materials, foundation and ROI deep-dive, see our companion read: Cost to build a new garage in Auckland — the full breakdown.

What does it actually cost to build a garage in Auckland in 2026?

Here are the ranges we’re seeing in the Auckland market this year. These are full-build figures — design, consent, foundation, framing, cladding, roof, doors, basic electrical, and project management. Not kitset prices, and not bare-shell prices either.

Auckland sits at the top end of the national range. Labour rates here run roughly 10–20% above the rest of the country, materials carry an Auckland delivery premium, and consent processing is slower and dearer than in smaller council areas. Sites with sloping ground, reactive clay, or tight vehicle access push the foundation and excavation cost up before a single piece of framing goes in.

💡 Quick tip: When you compare quotes, check whether the figure is “supply only”, “supply and install”, or “turnkey including consent”. A $35,000 quote can become $55,000 once you add the slab, consent, and connection to power — and most kitset sellers don’t include any of those.

Basic, mid-range or high-end: what each budget buys for a double garage

Two double garages can sit $40,000 apart and both be “finished”. The difference is spec, not size. Here’s roughly what a Auckland double looks like at three budget levels, so you know which conversation you’re actually having before the quotes arrive.

Basic double — around $40,000–$48,000

A lock-up-and-leave structure. Standard slab on a flat, prepared pad, timber framing, pre-coated steel or aluminium cladding, a Colorsteel roof, a roller or manual sectional door, one light and a power point. No lining, no insulation. This is the right call for pure vehicle and storage use where the look isn’t critical and you’re never planning to spend real time in there.

Mid-range double — around $50,000–$65,000

Where most of our clients land. Automated sectional doors, insulation, GIB lining on the walls, LED lighting split across a couple of circuits, several power points, and cladding chosen to match or sit deliberately against the house. Warm enough and tidy enough to use as a workshop, gym, or overflow space without it feeling like a shed.

High-end double — around $70,000–$100,000+

A finished room that happens to hold cars. Premium doors, full insulation and lining, an epoxy or polished concrete floor, a sub-board with workshop-grade power, generous lighting, and cladding and roofing matched to the house so it reads as part of the property. Once you add an office nook, gym fit-out, or the first hint of plumbing, you’ve crossed into the habitable budget and the numbers climb again.

💡 Quick tip: The single most expensive way to build a garage is to under-spec it now and upgrade later. Running extra circuits, insulating, and pouring a thicker slab during the original build costs a fraction of retrofitting them into a finished structure.

Three real-world paths to a new garage — and what each one costs

Most of the confusion around garage pricing comes down to one thing: three completely different builds all get called “a new garage”. They cost different amounts, take different timeframes, and pull in different trades. Here’s how to tell them apart before you ask anyone for a quote.

1. Kitset garage — cheapest, most limited

You buy a flat-packed steel or aluminium structure from a retailer like Versatile or Totalspan. Sticker price for a single is around $4,000–$10,000; a double sits at $8,000–$15,000. Sounds great until you cost in the bits the kit doesn’t include: a concrete slab ($3,300–$3,900 for a standard 30m² pad on a prepared, flat gravel base in Auckland), site preparation, consent if you’re over the exemption thresholds (more on that below), connection to power, and either an installer’s labour or your own weekends.

Stack those add-ons on, and a kitset double realistically lands between $20,000 and $30,000 by the time it’s standing on a slab with a working door. It’s a sensible option for storage-only spaces on flat ground where the finish isn’t the point.

2. Site-built detached garage — the standard option

This is what most people picture when they think “new garage”. It’s framed, clad, and roofed on your section, built to either match your house or sit as a deliberate contrast. Materials, doors, lining, and door automation are all choices you make — which is why the range is wide. A site-built single in Auckland is roughly $25,000–$40,000 turnkey; a double sits at $40,000–$60,000 for a standard finish and $60,000–$80,000+ once you’re insulating, lining, and adding circuits.

A site-built garage gives you a structure that genuinely looks like part of the property, which matters at resale. homes.co.nz data on Auckland sales consistently shows properties with secure off-street parking holding their own against, or ahead of, their no-garage neighbours — and in central suburbs the gap widens. A dedicated park in Ponsonby or Herne Bay carries real weight.

3. Attached garage as part of a house extension — our most common garage job

Roughly 60% of the new-garage enquiries we get aren’t standalone garage jobs at all. They’re extension projects where the garage forms part of a wider footprint change — a garage with a master bedroom above, a garage extending off the existing kitchen wall, or a double replacing a single and tying into a new utility room. These start around $50,000 for the garage portion and run to $100,000+ once you factor in the new foundation tied to the existing house, weatherproofing the junction between old and new, and the consent work an extension always needs.

The upside is that you only do the disruption once. Instead of building a detached garage now and renovating the house in five years, you change the home’s footprint and finish in a single project. If your project is closer to “extension with a garage” than “garage on its own”, it’s worth looking at it as a wider extension from the start — and our house extension cost calculator is the right tool for that scope.

“We’ve had clients in Albany and Glendowie start the conversation asking for a detached garage and finish it building an attached double with a sleepout above. The reason isn’t upsell — it’s that once you’re spending $40,000 on a separate structure, an extra $30–40k turns it into useable family space for the next ten years. The maths shifts pretty fast when you draw it on paper.”
— Dorothy Li, Design Manager, Superior Renovations

Do you need consent for a garage in NZ? What changed in 2020, 2025 and 2026

This is the part most online guides get wrong. The old rule everyone quotes — “you need consent for anything over 10 square metres” — was superseded in August 2020 when Schedule 1 of the Building Act was updated. Then the boundary rules changed again in October 2025, and a brand-new granny flat exemption started on 15 January 2026. If a guide still cites only the 10m² threshold and the “own height” setback rule, it hasn’t been refreshed in years.

Here’s where the rules actually sit in 2026, drawn from MBIE’s exempt building work guidance and Auckland Council’s requirements. When you’re not sure, MBIE and Auckland Council run a free “Can I build it?” checker for garages that walks you through it.

Detached single-storey buildings (the garage path)

A detached single-storey building — including a fully enclosed garage — can be built without a building consent in two main ways:

• Up to 10m², no LBP needed — genuinely small structures only. A standard single garage is about 21m², so this rarely covers a real garage.
• Between 10m² and 30m², if the design and construction are carried out or supervised by a Licensed Building Practitioner — this is the post-2020 change. It lets a compact detached garage be built without a building consent, as long as an LBP signs off the design and supervises the work. There’s also a parallel route for lightweight timber or steel structures built to Acceptable Solution B1/AS1, which in some cases can be done without a professional.

There’s a catch: the structure can’t include sanitary facilities, cooking facilities, or a potable water supply. Pure garage use — vehicle storage, workshop, hobby space — is fine. The moment you add a toilet or a kitchen, it becomes a different building and the exemption falls away.

The boundary setback rule changed in October 2025

This is the bit even recent guides get wrong. The old rule said a detached building had to sit at least as far from the boundary as it was tall — the “own height” rule. That was scrapped on 23 October 2025. Now a structure under 10m² can be built right up to the boundary, and a 10–30m² building needs to be set back just one metre from any boundary or other building. For tighter Auckland sections — think the older quarter-acre splits through West Auckland and the Shore — that change quietly makes a compliant detached garage possible where it wasn’t before.

Carports are treated more generously

Carports — open-sided shelters, not fully enclosed garages — have their own, more generous exemption rules than enclosed garages. If you only need vehicle cover and don’t need walls, a carport gets you under the consent rules with far more room to move. The exact size allowance and conditions are set out in MBIE’s exempt building work guidance, so confirm your design against that before you build.

The 2026 granny flat exemption (Schedule 1A)

This is the newest change, and the one that matters most for garage-with-sleepout plans. From 15 January 2026, an eligible standalone dwelling up to 70m² can be built without a building consent under the granny flat exemption, provided it meets a defined set of design, siting, and trade-qualification rules and uses licensed professionals. If your “garage” is really a garage-plus-sleepout-plus-bathroom of around 60–70m², the cleaner legal route is often this exemption rather than trying to wedge it under the garage rules. It costs more than a plain garage, but the consent path is faster.

Attached garages and anything you build onto the house

An attached garage almost always needs a building consent. You’re altering the primary structure of the home — adding a foundation, changing the roofline, breaking through an exterior wall, often shifting drainage. There’s no Schedule 1 exemption for that. Auckland Council consent fees for a residential extension typically run $3,000–$8,000, with processing of 4–8 weeks for a straightforward application. Add 6–10 weeks before that for architectural drawings and engineering, depending on complexity.

Important note: Even when work doesn’t need consent, it must still comply with the Building Code and your Auckland Council district plan — site coverage, setbacks and height-to-boundary rules all still apply. Building without a required consent carries fines up to $200,000 under the Building Act 2004, plus daily penalties for ongoing offences. If you’re unsure, request a free feasibility report before you commit to a build path.

For consent-related garage projects, we work with Sonder Architecture, our architectural partner. Sonder pulls the property file from Auckland Council, runs the feasibility study, and produces the drawings needed for consent submission. If you want to read the current exemption picture in full, their guide on what you can build without consent in NZ covers every threshold. Same process we run for every extension and conversion job.

What actually pushes a garage cost up (and what barely matters)

The line items that move a quote aren’t always the ones homeowners expect. Door brand and roof colour barely shift the bottom line. Site conditions, lining choices, and the consent path absolutely do.

Foundation and site preparation

A flat, accessible site with good ground is the cheapest scenario — a standard 30m² concrete slab in Auckland runs roughly $3,300–$3,900 for materials and labour on a prepared gravel pad. Add reactive clay, a sloping section, or a driveway the concrete truck can’t reach, and that figure can double or triple. We had a job in Titirangi last year where the slope meant a chunk of retaining and levelling had to happen before the slab could even be poured — the groundworks cost more than the garage shell. Older villas through Grey Lynn, Ponsonby, and Mt Eden often sit on sites that need that kind of work first.

Lining, insulation, and electrical fit-out

An unlined garage with a single light and one power point is the bottom of the range. Add insulation (around $500–$1,500 for a single, more for a double), GIB lining ($1,500–$3,500 fitted), LED lighting on multiple circuits, and a few power points or a sub-board, and you’re easily $5,000–$10,000 past the bare-shell quote. Worth doing if the space will see real use — workshops, gyms, home offices — and worth skipping for pure storage.

Door choice

Sectional doors with automation are standard now, sitting at $1,800–$3,500 supplied and installed for a single. Roller doors are cheaper at around $1,200–$2,000. Premium aluminium-panel or timber-look doors push past $5,000 for a single and $8,000 for a double. The difference between a $2,000 door and a $5,000 door is cosmetic — they all open and close the same way.

Habitable add-ons (the big multiplier)

The moment plumbing enters the brief, the cost scales. A basic bathroom in a garage-sleepout combo adds $20,000–$25,000 once you account for drainage runs, waterproofing and ventilation. A kitchenette adds $8,000–$15,000. Heating, ventilation, and double glazing for genuine year-round use add $5,000–$10,000. That’s why a garage with a sleepout sits at $80,000+ rather than $50,000 — you’re effectively building a small dwelling.

“The single most useful thing a client can do before getting quotes is decide whether the garage is for storage or for living. The trades involved, the materials we spec, the consent path, the budget — all of it changes. Trying to keep both options open ends up costing more, because we have to build to the higher standard just in case.”
— Alison Yu, Designer, Superior Renovations

How Superior Renovations handles a new garage project

New garages aren’t the typical kitchen or bathroom job, but they sit naturally in our work for one reason — most Auckland garage builds turn into extension projects, and extensions are our wheelhouse. Here’s the process when a garage enquiry comes through.

Your enquiry comes to us first. We talk through what you’re after — storage, workshop, a second vehicle, an eventual sleepout — and the constraints of your section. If the project needs consent, we introduce you by email to Sonder Architecture straight away. Sonder requests your property file from Auckland Council, runs an on-site feasibility study, and tells you what’s actually possible under your zoning and district plan. That step alone saves clients from paying for designs that can’t be consented.

If the project stacks up, Sonder produces concept drawings and quotes the full architectural set. Once those are done, our renovation consultant visits the site, measures up, runs through the design and material options with you, and produces a fixed-price proposal with full specifications — no estimates, no “to be confirmed” lines. Auckland Council consent goes in, and we start once it’s granted.

For garages with a habitable area — sleepout, office, gym, or self-contained granny flat — our Design Studio handles the interior. Joinery, lining, lighting and material selection all happen at our Wairau Valley showroom (16B Link Drive) so you can see the finishes in person before you sign off.

If you’d rather spread the cost, our 18-month interest-free option through Q Mastercard is set out on the finance options page.

House Extension Cost Calculator NZ — Your Estimate in 60 Seconds

Quick answer: Get a personalised house extension cost estimate emailed straight to your inbox in under 60 seconds. No phone calls, no sales pitches, no waiting on a builder’s diary. Tell us your project basics, and we’ll send back a project-specific number based on real 2026 Auckland pricing.

You’re thinking about extending. You’ve done the basics — pulled up online ranges, looked at a few builder websites, probably had a mate at a barbecue throw out a figure that may or may not be from this decade. What you actually need is a number that fits your project. Your house. Your section. Your space.

That’s what this calculator gives you.

Why a Calculator Beats a Generic “Per m²” Estimate

Most online sources will tell you a house extension in Auckland costs $2,000–$5,500 per square metre. That’s accurate. It’s also useless for budget planning.

The range exists because extensions vary wildly. A 30m² bedroom addition on a flat section in Flat Bush sits at the bottom end. A 50m² addition with a new kitchen and bathroom on a sloping site in Titirangi sits near the top. Both are “house extensions in Auckland.” Both are technically inside that $2,000–$5,500 spread. Both cost vastly different amounts.

The per-m² range alone doesn’t tell you which one you are.

That’s where the calculator earns its keep. Instead of giving you a number that covers everyone, it asks the specific questions that move your number — size, type of rooms, whether you’re going up or out, site complexity — and gives you a tailored estimate based on what those choices actually cost in Auckland right now.

It takes about a minute. Results land in your inbox.

What Goes Into the Estimate

The calculator works through the same variables we use when we’re pricing a real project. None of it’s guesswork — every input maps to a cost driver we’ve seen on completed Superior Renovations jobs.

Built from data across hundreds of Auckland renovations completed since 2018 — including ground-floor extensions, second-storey additions, and garage conversions.

Size of the extension. Square metres is the starting point — but it’s not linear. A 30m² extension often costs more per square metre than a 60m² one because fixed costs (consents, design, engineering) don’t scale down. The calculator factors that in instead of just multiplying area by a flat rate.

Type of space. A dry room — bedroom, living area, study — costs significantly less than a kitchen or bathroom. Wet areas need plumbing, waterproofing, ventilation, and higher-spec fixtures. Adding a bathroom to an extension typically adds $25,000–$45,000 on top of the dry-room build cost.

Single or double storey. Going up is more expensive than going out — usually 40–60% more per square metre once you factor in structural reinforcement, scaffolding, and the work needed to make the existing house carry a new floor.

Site conditions. Flat section or sloped? Easy access for trucks and trades, or a tight build? Volcanic clay, reactive soil, or a straightforward concrete slab job? Foundations alone can swing the budget by $30,000+.

Finish level. Standard weatherboard and vinyl plank, or cedar cladding and engineered timber? The choice between budget and premium materials makes a five-figure difference on most extensions.

You don’t need to know exact specs going in. The calculator gives you a sensible default for each input — your job is to tell it what you’re roughly planning, and the estimate adjusts to suit.

What You Get in Your Inbox

A couple of minutes after you submit, you’ll receive an email with a project-specific estimate. Here’s what’s in it:

A low-to-high range based on the inputs you provided. Not a single point estimate — because no honest builder gives you one before a site visit. The range shows you where your project realistically sits.

A breakdown of the main cost categories — construction, finishes, professional fees, consents — so you can see where the money goes and where the biggest swings are.

Notes on what the estimate doesn’t include. Typically GST, resource consent (if triggered), and any unforeseen ground or structural issues that only become visible once construction starts. We’d rather flag the limits than pretend they don’t exist.

It’s not a quote. Quotes need site visits, drawings, and detailed scope. The estimate is the layer before that — the number that tells you whether your project sits in a budget you can work with, or whether you need to rescope before going further.

If the number looks workable, the next step is usually a feasibility consultation, where we walk through your specific property, what you’re trying to achieve, and what’s realistic on your section. That’s a separate conversation — and one you can book after you’ve seen the estimate, not before.

The Three Variables That Move Your Number the Most

If you’ve used the calculator and want to understand what drove your result, these three factors do most of the heavy lifting.

1. Foundations and structural work — 20–40% of the total. The single biggest swing factor on most Auckland extensions. A flat-section ground-floor extension on basic slab foundations is dramatically cheaper than a second-storey addition needing steel beams, reinforced foundations, and scaffolding. If you’re on a steep site in Titirangi, Mt Eden, or Remuera, expect this category to push higher because of piling and retaining work.

2. Wet areas — kitchen and bathroom additions. Adding either to your extension materially increases the per-m² rate. Bathrooms add $25,000–$45,000. Kitchens add $28,000–$50,000. If your goal is purely more living space, a bedroom or open-plan living extension is going to come in considerably lower than the same square metres with a kitchen or bathroom inside it.

3. Labour and trade coordination — 40–50% of the total. Auckland trade rates currently sit at $90–$120/hour depending on the trade. A 50m² extension typically needs 800–1,200 trade hours. The reason fixed-price builders quote higher than charge-up builders isn’t margin — it’s the risk premium for guaranteeing the number. The flip side: charge-up budgets often blow by 15–20% once schedule slip and coordination losses kick in.

Knowing which of these three is the biggest factor on your project tells you where to focus when you’re trying to bring the number down — or where to brace yourself if it has to stay where it is.

Frequently Asked Questions

Please note: Cost factors vary project to project, and the calculator’s accuracy depends on the inputs you provide. The estimate is a planning tool, not a quote. Rates and material costs shift with the market, and final project pricing requires a site visit and detailed scope. While information is considered current at the date of publication, Superior Renovations isn’t liable for any decisions made solely on the calculator output.

Bathroom Cost Calculator: Get a Real Auckland Renovation Estimate

Quick answer: Our free bathroom cost calculator gives Auckland homeowners an indicative renovation estimate in under 60 seconds, based on real 2026 figures — a mid-range bathroom in Auckland runs $25,000–$35,000, and the calculator helps you see where your project sits before you talk to anyone.

Most people start a bathroom renovation with a number in their head. Usually it’s wrong. Either it came from a mate’s job three years ago, or a clickbait headline about a $9,000 bathroom that turned out to be a paint-and-fittings refresh, not a real renovation.

A bathroom cost calculator exists to replace that guess with something closer to reality. Ours was built by the team that quotes and builds these renovations every week across Auckland — not borrowed from a national average that ignores the city’s labour rates. Punch in your details, get an indicative range emailed to you, and start the conversation already knowing roughly what you’re dealing with.

Here’s how to use it properly, what the number means, and the things no calculator can see.

What the Bathroom Cost Calculator Actually Does

The tool asks you a handful of questions — bathroom size, the type of work, your finish level — and returns an indicative cost range for your renovation. It takes less than a minute, and the breakdown lands in your inbox.

It’s an estimate, not a quote. That distinction matters. A calculator works off averages and the inputs you give it. A quote comes after a designer has stood in your bathroom, seen the state of the framing, checked where the pipes run, and worked out exactly what your job needs. The calculator gets you in the right ballpark. The consultation gets you the actual number.

Why a Renovation Company’s Calculator Beats a Generic One

Search “bathroom cost calculator” and you’ll find plenty of tools run by sites that don’t actually renovate bathrooms. Some of them point you off to three other calculators. That’s not much use when you’re trying to budget for a real job in Glen Eden or Howick.

Ours is different for one simple reason: the numbers behind it come from jobs we’ve actually delivered. When the calculator says a mid-range bathroom is $25,000–$35,000, that’s not a number we found online. That’s what these renovations cost in Auckland right now, including design, supply, all trades, and project management.

“People treat the estimate like a price tag, and it isn’t one. What it’s really good for is telling you whether your wishlist and your budget are even in the same room. If you’ve got $20,000 in mind and a full wet-room plan, the calculator will show you that gap before you’ve spent a cent on design.”
— Cici Zou, Designer (NZ Dip. Interior Design, Certified Designer), Superior Renovations

💡 Quick tip: Run the calculator twice — once at your dream spec and once at a more modest one. The difference between the two numbers tells you exactly where your money is going, and where you’ve got room to compromise.

How to Read Your Bathroom Renovation Estimate

You’ve got your range. Now what does it actually mean? The calculator sorts most Auckland bathroom renovations into three tiers, and knowing which one you’re aiming for makes the estimate far more useful.

The Three Tiers, in Plain Numbers

These reflect 2026 pricing, which sits roughly 5–8% above 2025 after another round of material and labour inflation. Auckland runs 20–30% above the national average, mostly down to higher labour rates of $90–$120 an hour and city material costs. If a calculator gives you a number well below these and claims to be NZ-specific, it’s likely quoting a national figure or leaving out trades.

What the Estimate Doesn’t Include

This is where most budgets come unstuck. The headline range covers the planned work. It does not automatically cover the surprises — and bathrooms, of all rooms, are where surprises live.

Behind the tiles and under the floor of an older Auckland home, you can find rot, failed waterproofing, or plumbing that should’ve been replaced a decade ago. We had a job in a 1930s Mt Eden villa last year where the floor framing under the shower had quietly turned to compost. Nobody could’ve priced that off a calculator. The fix runs from a few hundred dollars to several thousand, which is exactly why we tell every client to hold back a contingency of 10–15% on top of their estimate.

Important note: Treat your calculator estimate as the cost of the visible job. Add 10–15% on top for the things that only show up once the demolition starts. On a $30,000 renovation, that’s $3,000–$4,500 set aside — far better than finding it mid-build.

If you want the full tier-by-tier breakdown with line items, our Auckland bathroom renovation cost guide for 2026 goes deeper than a calculator can.

The Factors That Move Your Calculator Number Most

Two bathrooms the same size can come back with wildly different estimates. Here’s what’s pulling the number around — so when you run the tool, you know which lever you’re pulling.

Whether the Plumbing Moves

This is the single biggest swing. Keep the toilet, basin, shower, and bath roughly where they are and you keep costs down. Relocate the shower or move the toilet to the other wall and you’ve added $5,000–$10,000 in plumbing alone, before you’ve touched a tile. Moving services is also one of the main triggers for needing Auckland Council consent.

Tile Choice and Area

Tiles are sneaky. A 6m² bathroom tiled floor-to-ceiling is closer to 30m² of tile once you count the walls. Double the price per square metre — say from a $40/m² ceramic to a $120/m² porcelain — and you’ve added well over a thousand dollars on that line alone. The Tile Depot is a good place to compare what your range actually buys you.

Tapware, Joinery and the Vanity

An off-the-shelf vanity sits around $800–$2,000. A custom NZ-made one with a stone top is $4,500–$8,000-plus. Tapware does the same thing quietly — the gap between entry-level and premium across your mixer, shower, and basin can swing the total by $2,000–$4,000. Brands like Reece are worth a look to see where your spec lands.

“The calculator can’t tell you which $3,000 is worth spending. That’s the bit we love about the consultation — sometimes the smartest move is a modest vanity and a really good tap, not the other way round. Spend where your hand actually touches the bathroom every day.”
— Alison Yu, Designer, Superior Renovations

💡 Quick tip: Before you run the calculator, decide one thing — are you keeping the existing layout? That single answer changes your estimate more than any other input, because moving plumbing is the most expensive thing you can do in a bathroom.

If you’re weighing up the bigger picture first, our full bathroom upgrade page walks through how we run a full project end to end.

From Estimate to Real Quote: What Happens Next

So you’ve run the numbers and the range feels workable. Where to from here?

The calculator’s job is done — it’s told you whether your project is realistic and roughly what to budget. The only way to get an accurate, fixed price is a free in-home consultation, where one of our designers sees the actual space. That’s when the unknowns become knowns: the state of the substrate, where the pipes really run, whether your plan triggers consent.

Do You Need Consent? The Calculator Can’t Tell You

Most straightforward bathroom renovations — new tiles, vanity, toilet, and shower in the same spots — don’t need Auckland Council consent. You’ll need it if you’re moving plumbing to a new location, removing or adding walls, or making electrical changes beyond like-for-like swaps. Consent isn’t just a cost; it’s time — Auckland Council processing typically adds 4 to 8 weeks before work can start. Worth knowing before you set a move-in-ready deadline. You can check the current rules on the MBIE Building Performance site.

Why Talk to a Renovation Company Rather Than Piece It Together

A full bathroom renovation pulls in 8 to 10 different trades — demolition, plumbing, electrical, waterproofing, tiling, cabinetry, painting. Coordinating that lot yourself is the single biggest source of stress for homeowners who go it alone. Superior Renovations runs all of it as one job: in-house design, fixed-price contract, one project manager, a 147-point quality check, and a 12-month workmanship warranty on top of the trade warranties. It’s the difference between an estimate on a screen and a finished bathroom that doesn’t leak in two years.

Our showroom at 16B Link Drive, Wairau Valley is open if you’d rather see real tiles, vanities, and tapware in person before you commit to a spec.

Reroofing Cost Calculator NZ — 2026 Auckland Roof Replacement Costs

Quick answer: Reroofing a standard Auckland home in 2026 costs around $14,000–$32,000 for long-run Colorsteel — the most common roof in NZ — and $22,000–$45,000+ for concrete or clay tile. Use the calculator below for an estimate on your roof, or book a free site visit and we’ll measure it ourselves.

Jump to Cost Calcultor Tool

What does reroofing actually cost in Auckland in 2026?

The honest answer is: it depends on three things — the size of your roof, what’s going on top, and how hard it is to get to. The figures below are realistic ranges for fully installed reroofs on standard Auckland homes in 2026, including strip-out of the old roof, new underlay, fixings, flashings, ridge capping and disposal. Scaffolding and any framing or purlin work are extra. Reroofing is often done at the same time as recladding and exterior renovation, which can save on scaffolding and access costs.

For context: residential building costs are no longer running away. The Stats NZ Capital Goods Price Index for residential dwelling units rose from 1,094 (September 2025) to 1,102 (December 2025), reflecting modest stabilisation after the post-COVID surge. That makes 2026 a fair time to lock in fixed-price quotes before the next cycle.

💡 Quick tip: Asphalt shingles get quoted in some online calculators at $5,000–$12,000. Skip them. In NZ they’re a rounding error in the market — UV, salt air and driving rain chew through them in 15 years. Long-run Colorsteel is the realistic baseline for almost every Auckland home.

“People look at the upfront price of asphalt shingles and think they’ve found a bargain. They haven’t. Auckland’s UV, salt air and rain chew through them in 15-odd years. Long-run Colorsteel costs more on day one and outlasts shingles three or four times over. Over a 40-to-60-year horizon, it’s almost always the cheaper roof you’ll ever buy.”
— Alison Yu, Designer, Superior Renovations

What pushes your reroofing price up (or down)

Two roofs on the same street can quote $5,000 apart. Here’s what actually moves the number:

Pitch and access

A flat or low-pitch roof (under 20°) sits on standard labour rates. Steep pitches over 30°, valleys, dormers and multi-level designs lift labour by 30–80% because the team needs safety harnesses, edge protection and more staging time. Hillside and bush-fringe suburbs — Titirangi, Beach Haven, Birkenhead, Glenfield — almost always need scaffold, which adds $2,000–$8,000 on its own.

Roof size and complexity

A simple 150m² single-storey gable roof in Henderson or Manurewa lands at the friendlier end of the range. A 220m² two-storey with hips, valleys, two dormers and a chimney in Remuera or Epsom lands at the upper end — or above it.

What’s underneath

Once the old roof comes off, the team can finally see the substrate. Rotted purlins, soft battens, water-damaged framing — none of it is visible from the ground. We’d be lying if we said this never adds cost. Most fixed-price quotes carry a 10–15% contingency for exactly this reason, and you only spend it if something needs fixing.

Asbestos (pre-1980s homes)

Roofs installed before the mid-1980s often contain asbestos — Decramastic-style pressed metal tiles and some bitumen products are the usual culprits. This catches owners of pre-1980s character homes across Mt Eden, Onehunga, Grey Lynn, Sandringham and Mt Roskill off guard. Per WorkSafe NZ rules, asbestos-containing material must be identified and removed by a licensed asbestos removalist when disturbed. Testing and safe removal adds $3,000–$15,000 depending on roof size and condition. We test before quoting on any older home — it’s part of the free site visit.

💡 Quick tip: If your home was built before 1985 and the roof has the original tiles, get the asbestos test done before you collect quotes. A clean test result lets every roofer quote on the same basis — no nasty surprises mid-job.

Reroofing Cost Calculator — Auckland Homes

Drop your roof size, material preference and basic complexity below. The calculator emails you a ballpark estimate based on 2026 Auckland market data. It’s a starting range, not a final number. Tick the callback box if you’d like us to talk you through it.

What the calculator does and doesn’t cover

Included in the estimate

Supply of the chosen roofing material and underlay. Removal and disposal of the existing roof. Standard fixings, flashings and ridge capping. Labour for a typical pitch and standard access. Project management and quote prep.

Not included (because every home is different)

Scaffolding (priced separately based on access — typically $2,000–$8,000). Framing, purlin or batten replacement if rot is discovered. Spouting and downpipe replacement ($45–$80 per linear metre installed if you choose to bundle it). Building consent fees where the work isn’t a like-for-like replacement (around $1,500–$5,000 via Auckland Council). Asbestos testing and licensed removal where required.

Important note: Most straightforward like-for-like roof replacements (same position, comparable materials) are exempt from building consent under Schedule 1 of the Building Act 2004. Consent is required if you’re changing roof type, pitch or weight (e.g. metal to concrete tile), making structural alterations, or the original roof has failed the Building Code. We check this on every Auckland job before quoting.

Should you reroof, or reroof and reclad together?

If your home is a 1990s or early-2000s monolithic plaster build and the roof is failing, this is the question worth pausing on. The leaky-building era left thousands of Auckland homes with both a tired roof and compromised cladding. Doing them as two separate projects across two years is almost always more expensive than doing them together.

Why? Scaffolding is the big-ticket overlap — it’s already up for the reclad, and adding the roof to the scope barely moves the scaffold bill. Consent can often be batched into a single application. The team is already on site. And you live through the disruption once, not twice.

“If your home’s a 1990s or early-2000s plaster build and the roof is at end of life, that’s a moment to stop and think. Scaffolding’s already up. Consent can be batched. Doing the reroof and reclad in one go often saves 10–15% off the combined cost, and you only live through the disruption once.”
— Dorothy Li, Design Manager, Superior Renovations

If you’re in that situation, our cost of recladding a house in Auckland guide walks through the combined economics. Or just request a free feasibility report and we’ll scope it for your specific home.

What happens after you submit the calculator

The estimate lands in your inbox within a few minutes (check the junk folder if it doesn’t show). If you ticked the callback box, one of our team rings within a couple of working days to talk through what’s in the number and what isn’t. From there, the next step is a free in-home consultation — we measure the roof, check the substrate from below, test for asbestos if relevant, and come back with a fixed-price quote.

No obligation. No pressure. If reroofing alone isn’t actually what you need, we’ll tell you.

Pergola Cost Calculator NZ: What a Custom Auckland Pergola Costs in 2026

Quick answer: A professionally built pergola in Auckland costs between $10,000 and $45,000 in 2026, depending on size, material, and whether you go fixed-roof or motorised louvred. Use our free pergola cost calculator below to get a tailored estimate in under 60 seconds.

The straight answer first: a professionally built pergola in Auckland in 2026 sits between $10,000 and $45,000 for most builds. The wider real range stretches from around $4,000 for a basic timber kit-set DIY at the bottom to $70,000+ for a premium louvred outdoor room with lighting, heating, and screening at the top.

What the headline number doesn’t tell you is what your money actually buys. A $12,000 timber pergola and a $32,000 aluminium louvred pergola are two completely different products that happen to share a name. Knowing which one fits your section, your sun, and your budget is the difference between getting it right first time and replacing it in five years.

This page breaks down what each tier gets you in Auckland in 2026, what drives costs up or down, and how to read your pergola quotes without missing the gaps. Our free pergola cost calculator gives you a tailored estimate based on your specific size, material, and finish — it takes under 60 seconds.

How our pergola cost calculator works

We built the calculator for the question we get asked most: “what’s this going to cost me before I get builders out?” It returns a realistic estimate for a custom aluminium-framed pergola in Auckland based on the five inputs that move the price the most — size, finish colour, roof type, site complexity, and whether it’s freestanding or attached to your home.

You fill it in, your estimate lands in your inbox in under 60 seconds, and you’ll have a starting figure to work with before any quotes come in. We’ll follow up to walk through your number and answer questions — no pressure to book anything.

➡ Open the Pergola Cost Calculator
Get your Auckland pergola estimate in your inbox in under 60 seconds.

What the calculator covers

• Custom aluminium-framed pergola (3mm thick — NZ standard spec for residential)
• Powder-coated finish (black or white as standard)
• Clear PVC or polycarbonate roof panel
• Supply and installation in Auckland
• Standard footings on a typical residential section

What it doesn’t cover (these get costed separately)

• Electrical works — LED lighting, motorised louvres, automation ($800–$2,000)
• Adjustable louvre roof systems (different rate — typically $1,200–$2,500/m²)
• Scaffolding if your site needs it
• Deck construction or ground levelling
• Screening blinds (Ziptrak-style) — $3,000–$8,000 per blind, manual or motorised
• Outdoor heating units — $600–$1,200 per heater plus install

💡 Quick tip: Run the calculator twice — once for your wishlist size, once for a slightly smaller version. The second number is often the one that gets the project moving without compromising the look you want.

What does a pergola cost in NZ in 2026?

Pergola pricing in 2026 lands on a per-square-metre rate of roughly $900–$2,200 fully installed. The bottom of that range covers a simple open timber structure on a flat, accessible site. The top covers a motorised louvred system with the bells. Here’s the proper breakdown by build type, all figures GST-inclusive for supply and professional installation.

A few notes on the figures above:

• Auckland labour sits at the higher end of the national scale — typically $85–$130 per hour for carpentry and structural work. Outside Auckland you can usually take 10–20% off.
• A standard 20m² pergola takes two installers 2–4 days, depending on footing requirements and site access.
• Aluminium has overtaken timber as the modern default for Auckland — it’s rust-proof in salty Takapuna or Piha air, doesn’t warp under our humidity, and skips the yearly reseal that timber needs.

“Pricing a pergola isn’t like pricing a kitchen — there’s no fixed kitchen-shaped product to compare. A $12k pergola and a $32k pergola might both be 25m² in the same suburb. What changes is the material grade, the post and beam spec, the roof system, and what’s hidden in the footings. We walk every client through that breakdown before they sign anything.”
— Dorothy Li, Design Manager, Superior Renovations

What your pergola budget actually buys in Auckland (2026 tier breakdown)

Cost ranges are useful for shock-proofing your expectations. What you actually need to know is what each tier gets you on the ground. Here’s what we see across our 1000+ completed Auckland projects when we slot builds into budget tiers.

$10,000 — entry custom pergola

What you get at this tier:

• Treated timber pergola, freestanding, 12–15m²
• Open beam roof or basic polycarbonate panels
• Standard footings on a flat, accessible section
• One coat of exterior stain or paint

Suits: Smaller backyards in Henderson, Manurewa, or Hobsonville new builds where the section layout is straightforward. Schedule 1 exempt in most cases.

What you don’t get: aluminium framing, oversized spans, electrical, screens, louvres.

$20,000 — standard professional build

What you get at this tier:

• 18–25m² timber or basic powder-coated aluminium pergola
• Better roof options: tinted polycarbonate or clear PVC
• Footings rated for medium wind zone (most central Auckland suburbs)
• Possible deck integration as an extra
• LBP sign-off on structural work

Suits: Typical 1970s brick-and-tile homes in Manurewa or Pakuranga, family villa rear extensions in Mt Eden where access is reasonable. Most builds in this tier stay Schedule 1 exempt if freestanding.

$30,000 — proper aluminium custom

What you get at this tier:

• 20–30m² powder-coated aluminium pergola, black or white
• Higher-spec roof: clear PVC or polycarbonate with proper drainage detail
• LED lighting integration possible (separate electrical run)
• Often paired with deck work or paving
• LBP structural sign-off included

Suits: Remuera or Glendowie character homes wanting indoor-outdoor flow off a kitchen-dining renovation. Coastal North Shore builds where rust-proof spec matters. Approaching the 30m² consent threshold — Sonder Architecture handles consent in-house if needed.

$45,000+ — louvred outdoor room

What you get at this tier:

• 25–40m² motorised louvred pergola
• Adjustable louvre system — open in winter sun, close before a shower hits
• Integrated LED lighting and often outdoor heating
• Engineered structural design for high or very-high wind zones
• Often paired with screening blinds (Ziptrak) and complete new deck
• Building consent included where required

Suits: Premium renovations in Herne Bay, Westmere, Takapuna; clients wanting genuine four-season outdoor use. The premium isn’t the aluminium — it’s the louvre mechanism, the engineering, and the integration.

💡 Quick tip: Adding a single Ziptrak screen ($3,000–$8,000) often makes a fixed-roof pergola feel as functional as a louvred one — for half the spend. Worth modelling both before you commit.

“The mistake we see most often is clients pricing a louvred pergola without thinking about whether they’ll actually use the louvres. If the pergola faces north and you only use it in summer, a fixed-roof with a Ziptrak screen on the western side does the same job for $15k less. We always ask about orientation before we recommend a system.”
— Alison Yu, Designer, Superior Renovations

Plug in your size and material — see where your build lands.

What drives pergola costs up or down

Six things move the number the most. Get a handle on these and you’ll read any builder quote far more confidently.

1. Material

Material is the single biggest cost lever. Roughly, supply rates per m² for NZ in 2026:

• Treated pine: $200–$450/m² — most affordable, needs sealing every 1–2 years
• Macrocarpa (NZ native): $400–$700/m² — natural durability, less chemical treatment
• Cedar: $600–$900/m² — premium softwood, rich colour, resists warping
• Fixed-frame aluminium (powder-coated): $500–$1,200/m² installed
• Motorised louvred aluminium: $1,200–$2,500/m² installed

Steel turns up occasionally for industrial-style builds. It’s heavy, needs galvanising or powder-coating to resist rust, and you’ll usually need a crane to install it. For most Auckland sections it’s not worth the complication.

2. Size

Bigger means more footings, more posts, more roof material, more labour hours, and at a certain point engineering sign-off. A 12m² and a 30m² pergola use similar materials per m², but the larger one needs structural calculations and may push you over the 30m² consent threshold (see consent section below).

3. Roof type

• Open beam: cheapest, no rain protection — fine for shade alone
• Polycarbonate or PVC fixed: adds $100–$300/m² over open beam
• Adjustable louvred (motorised): adds $700–$1,500/m² over a fixed roof, plus electrical install

4. Footings and site work

A flat, accessible site with stable ground gets standard footings, usually included in the quote. Steep section, clay soil, or restricted access (think a Grey Lynn villa with a 60cm side passage) costs extra. Expect $500–$1,500 added for concrete cutting and new footings on existing patios or decks.

5. Electrical, lighting, and heating

Running cabling from your switchboard for motorised systems, LED strips, or heaters: $800–$2,000 depending on distance and concealment. Infrared radiant heaters cost $600–$1,200 per unit plus install. For lighting and motorised louvre control, we usually spec products from PDL by Schneider Electric — purpose-built for NZ wiring standards.

6. Finish and detail

Powder-coat in standard Resene colours (black, white, Grey Friars, Ironsand) is included. Anything custom adds $400–$1,000. Timber finishes need a stain and seal every 1–2 years to keep the wood from greying out under Auckland UV — Resene’s exterior range from Mitre 10 handles this well.

➡ Estimate your build with these factors locked in
The calculator accounts for size, material, finish, and site.

Do you need consent for a pergola in Auckland? (And what it costs if you do)

The good news for most homeowners: a pergola doesn’t need a building consent. Under Schedule 1 of the Building Act 2004, freestanding pergolas under 30m² are generally exempt building work, provided they meet a few conditions.

Important note: Consent is generally required if your pergola is (1) attached to your house and over 20m², (2) freestanding and over 30m², (3) has a solid waterproof roof structure, or (4) breaches your boundary setback or daylight plane. Auckland heritage zones often add further restrictions — Ponsonby fringe, Parnell, Mt Eden character zones in particular.

When consent applies, expect:

• Building consent fee (Auckland Council): $1,500–$3,000, processing 10–20 working days. Confirm current fees with Auckland Council.
• Resource consent (if you breach setbacks, daylight planes, or site coverage): $2,500–$5,000+
• LBP-certified structural sign-off: required for attached pergolas 20–30m² — usually included if you’re using a Licensed Building Practitioner

The Auckland Unitary Plan generally requires pergolas to respect yard setbacks (1.5–3m from boundaries depending on zone) and height limits (typically 3–4m). Overhanging public areas or a neighbour’s land needs written approval.

“Boundary rules catch a lot of homeowners out — they assume their section is theirs to do what they like with, then find out they’re 80cm too close to the fence and the council wants the posts moved. We measure setbacks twice before anyone digs.”
— Cici Zou, Designer (NZ Dip. Interior Design, Certified Designer), Superior Renovations

💡 Quick tip: We handle the consent application in-house when it’s needed — same process we use on our renovation consents — so you don’t have to deal with Auckland Council yourself.

How to compare pergola quotes without getting caught

A $5,000–$10,000 gap between two pergola quotes for the “same” build is normal. What’s not normal is accepting the gap without knowing what’s actually different.

Here’s where the differences usually hide:

1. Beam span and post spacing

Cheaper quotes often use thinner beams spanning further, supported by fewer posts. Looks fine on paper. Sags or flexes in five years. Ask what beam dimensions are specified and at what spacing — a 240x90mm beam spanning 3m is a different product than a 200x50mm beam spanning 4m, even if both quotes call it a “pergola”.

2. Footing depth and spec

The NZ Building Code requires footings rated for your wind zone. Cheaper quotes may spec shallow footings sufficient for low wind but inadequate for Takapuna, Piha, exposed Westmere, or any coastal site. Ask: what depth, what diameter, what concrete spec? On a high wind zone site you should see 600–900mm deep footings minimum.

3. Fixing grade

Marine-grade stainless or hot-dip galvanised fixings cost more than basic zinc-plated. On a coastal pergola the difference is whether you’re replacing brackets in seven years or never having to touch them.

4. Consent and engineering inclusion

Some quotes exclude consent costs and engineering sign-off, expecting you to handle them. Get explicit confirmation either way — these are $1,500–$3,000 line items you do not want to discover after the fact.

5. Standard inclusions on the extras

Concrete footing preparation, removal of existing structures, anchoring to existing decks, gutter and downpipe integration — these are commonly excluded on cheap quotes. Ask line by line what’s in and what’s out.

💡 Quick tip: Ask each quoting builder for their Licensed Building Practitioner (LBP) number and check it on the LBP register at lbp.govt.nz. If they can’t give you one for structural work, walk.

Why two pergolas of the same size cost different across Auckland

Two clients ask for a 24m² aluminium pergola. One quote comes back at $26,000, the other at $34,000. Same product, different number. Here’s what causes the gap.

Site access

A Hobsonville new build with flat lawn and driveway access takes a different approach than a 1930s villa rear courtyard in Grey Lynn with a 60cm side passage. On the second, materials and waste move in and out by wheelbarrow, scaffolding goes up by hand, and labour hours stack up. That’s an extra $2,000–$4,000 in many cases — not a builder being greedy, just the reality of the site.

Ground conditions

Auckland’s geology shifts suburb by suburb. Clay slopes in Titirangi or West Harbour need deeper footings than the flat sand in Albany. Volcanic-fringe sites near Mt Eden or One Tree Hill can mean rock breaking on the way down. We’ve seen footing costs vary by $1,500–$2,500 between two builds based on ground alone.

Wind zone

Most central Auckland suburbs sit in medium wind zone per the building.govt.nz wind maps. Coastal Takapuna, Piha, exposed Westmere, or hilltop Titirangi can hit high or very high. Higher zones require thicker posts (150x150mm timber or 100x100mm steel minimum), deeper footings, and diagonal bracing per the NZS 3604 framing standard. That spec adds real cost — and skipping it on the wrong site is how pergolas come down in southerlies.

Sun, shade, and orientation

The cheapest pergola is the one you actually use. A north-facing pergola in Remuera that gets baked from 11am needs a different shade strategy than a south-facing courtyard in Hillsborough that’s already shaded for half the day. Material and roof type both shift based on orientation — a $2,000 louvre upgrade on the wrong-facing site is wasted money; on the right-facing site, it’s the difference between using the space in February and not.

“We always walk the site before we quote. Two sections that look the same on Google Maps can have totally different cost profiles once you stand on them — the wind, the access, the sun angle, the ground. A 30-minute site visit saves clients from variations later.”
— Eunice Qin, Designer, Superior Renovations

Pergola finance — 18-month interest-free

If you’d rather not deplete savings on outdoor work right now, we partner with Q Mastercard for 18-month interest-free finance on renovation projects from $1,000 up. Standard lending criteria apply — see our finance options page for the detail.

For most clients, finance turns a $25,000 louvred pergola from a “next year” project into a “this summer” one. The interest-free term covers a full year of using the pergola before the standard rate kicks in.

Double Glazing Cost Calculator NZ — 2026 Auckland Pricing

Most Auckland homeowners pay between $14,000 and $35,000 to double glaze a standard 3-bedroom home in 2026 — frame material, glass spec, and full replacement vs retrofit are what move the number. Skip ahead to the calculator for an indicative figure on your own home, or read on for the breakdown that explains why quotes vary so much between suppliers.

This page covers what you’ll actually pay in the current NZ market, where the money goes, what the H1 Building Code requires in 2026, when you need consent, and what double glazing genuinely changes in your home. The calculator gives a starting figure — the rest of the page tells you what to do with it. Finance is available if you need it (18 months interest-free via Q Mastercard, covered further down).

Double Glazing vs Retrofit Double Glazing — What’s the Difference

Double glazed sliding doors in West Harbour, Auckland.

A full double glazing job replaces the entire window — frame and glass — with a factory-made Insulated Glass Unit (IGU). Two panes of glass, a spacer bar between them, and either still air or argon gas in the cavity. The frame is new, the seal is new, everything is new.

A retrofit keeps your existing frame and slots a new IGU into it. Cheaper, less disruptive, and faster — but only viable if your existing joinery is in good enough condition to hold the new unit and stay weathertight. Old timber frames that have rotted, swelled, or warped won’t take a retrofit. Aluminium frames designed for single glazing often lack the depth to hold a double glazed unit without modification.

In short: full replacement is the better long-term result and the more common choice for renovations. Retrofit is the practical option for older villas and bungalows where original joinery needs to stay (heritage rules, character covenants, or just budget).

What Drives the Cost of Double Glazing in NZ

Nine factors push a double glazing quote up or down. The same house can get quotes $10,000 apart depending on how these stack up.

• Size and number of windows — the bigger the glass area, the more you pay per opening
• Frame material — uPVC, aluminium (standard or thermally broken), or timber
• Glass spec — standard clear, Low-E coating, laminated, toughened, tinted
• Cavity fill — still air (cheaper) or argon gas (better insulation, more expensive)
• Removal of existing windows — clean removal of aluminium is faster; rotten timber or asbestos-era plaster surrounds slow things right down
• Access — single-storey is straightforward; two-storey or sloping site work usually means scaffolding
• Changes to the opening — like-for-like is cheaper; resizing, adding a new opening, or changing the configuration adds reframing and reinstatement costs
• Consent requirements — like-for-like joinery is generally Schedule 1 exempt; new openings or structural changes trigger building consent and council fees
• Manufacturing lead time — bespoke sizes and shapes cost more than standard runs

2026 Double Glazing Cost Ranges — 3-Bed Home Example

The numbers below are full-replacement ranges for a typical Auckland 3-bedroom home with 10–15 window openings. They include supply, installation, removal of the existing joinery, and labour, but exclude consent fees, scaffolding for difficult access, and any structural alterations.

Cost by frame material — uPVC, aluminium, timber

What Low-E coating and argon fill add to the price

The frame is the base cost. Glass spec and cavity fill stack on top of it:

• Low-E glass — adds roughly 10–20% to the glass cost; reflects winter heat back into the room and blocks summer solar gain
• Argon-filled cavity — adds another 10–15%; cuts conducted heat loss compared with still air
• Laminated or toughened glass — required for safety glazing locations (doors, low-level windows, wet areas) under NZS 4223
• Tinted or solar control glass — useful for west-facing rooms and large north-facing glazing in summer

For most Auckland homes the Low-E plus argon combination pays for itself over the lifetime of the windows. For a small unheated garage window, standard clear with still air is fine — don’t pay for performance you won’t notice.

Retrofit double glazing cost — NZ pricing

Retrofit double glazing typically runs $18,000–$28,000 for an average 100m² Auckland home in good condition. Cheaper than full replacement, but the result is capped by the existing frames. If your aluminium frames weren’t designed for double glazing — which is almost certain if they were originally fitted with single panes — the frame itself will still leak heat regardless of what glass sits inside it.

H1 Energy Code 2026 — What’s Required for Auckland Windows

The Building Code’s H1 energy efficiency clause was updated in 2022 with a phased rollout, and the current schedule (5th edition, in force from May 2023 with subsequent updates) sets minimum construction R-values for windows based on six climate zones across New Zealand.

Auckland sits in Climate Zone 1 — the warmest zone — so the minimum window R-value requirement here is lower than for Wellington, Christchurch, or the South Island. That doesn’t mean spec to the floor. The minimum is a code threshold, not a comfort threshold. Hitting code with cheap glass means you’ll meet the inspector but still feel cold draughts in winter.

For Auckland specifically, the practical recommendation for any renovation worth doing is:

• Double glazed IGU as a baseline (single glazing won’t meet H1 for any consented new opening)
• Low-E coating for any window that will see direct sun or face the prevailing weather
• Argon fill where the budget allows — especially for living areas and bedrooms
• Thermally broken aluminium frames if you’re already paying for a high-spec build; standard aluminium is acceptable for retrofit-equivalent work

The full H1/AS1 schedule and current zone-by-zone R-value tables are published by MBIE at building.govt.nz. Window suppliers will quote against the latest schedule as part of their standard documentation — ask for the R-value of the system, not just the glass.

Do You Need a Building Consent for Double Glazing?

Like-for-like window replacement is generally exempt from building consent under Schedule 1 of the Building Act. If you’re swapping single-glazed windows for double-glazed units of the same size, in the same openings, with the same configuration, you can usually proceed without consent — provided the work is done by a Licensed Building Practitioner where Restricted Building Work applies.

You will need a building consent if you:

• Cut a new window opening into an exterior wall
• Materially change the size or position of an existing opening
• Replace a load-bearing lintel
• Make any change that affects the building’s structural performance or weathertightness in a way that goes beyond simple replacement

Resource consent is a separate question and can apply in character or heritage areas where window style affects the streetscape — Mt Eden, Ponsonby, Grey Lynn, Devonport, Parnell, and parts of Herne Bay all have overlays that can restrict what’s allowed visually, even when building consent isn’t required. Auckland Council’s planning maps are the authoritative source — check before you commit to a frame style or finish.

The current Schedule 1 exemptions list is maintained by MBIE at building.govt.nz.

What Double Glazing Actually Saves — Honest Numbers

Windows are typically the single biggest source of heat loss in an uninsulated or single-glazed home — often 30–40% of the total. Double glazing cuts that loss sharply. But the dollar savings on your power bill depend heavily on how you currently heat the house, what insulation you already have, and how you live in it.

EECA’s general guidance on whole-home insulation upgrades — ceilings, walls, floors, and glazing combined — points to real annual savings on heating costs. They don’t publish a single “savings figure” for double glazing alone, because in real homes the contribution depends on the rest of the building envelope. Anyone telling you a specific dollar payback is guessing unless they’ve modelled your home.

What’s reliable:

• Comfort — rooms hold heat overnight instead of bleeding it through the glass. Mornings are warmer. Heat pumps cycle less.
• Condensation — the inside pane stays closer to room temperature, so the daily winter mould-and-streak ritual largely disappears.
• Noise — measurable drop in road, neighbour, and aircraft noise. The bigger the air gap and the thicker the glass, the better.
• Resale — double glazing is now the expected baseline in Auckland renovations above $50,000. Single glazing reads as deferred maintenance.

Payback as a pure financial calculation is usually 10–20 years for a full replacement, shorter for a retrofit. Most homeowners don’t actually buy double glazing on payback maths. They buy it for the comfort difference, the noise reduction, and the fact that the next renovation, sale, or rental compliance check is going to require it anyway.

Healthy Homes and Double Glazing for Rentals

Double glazing isn’t a Healthy Homes requirement in itself. The Healthy Homes Standards cover heating, insulation, ventilation, moisture and drainage, and draught-stopping — but they don’t mandate window glazing type.

That said, single-glazed windows are usually the biggest source of condensation in a rental. Condensation is what drives mould complaints, Tenancy Tribunal cases, and the moisture and ventilation standard headaches landlords run into. Double glazing — or even retrofit double glazing on the worst-affected rooms — often does more for compliance than a second extractor fan ever will.

For landlords planning a between-tenancy upgrade, Superior Property Services handles maintenance, minor alterations, and Healthy Homes compliance work across Auckland — including coordinating glazing upgrades alongside heating and ventilation.

Tips to Reduce the Cost of Double Glazing

Not every window in a house needs the top spec. A few sensible trade-offs can drop a quote by 15–25% without hurting the result:

• Standard clear glass in low-priority rooms — garages, laundries, small bathrooms — where Low-E adds little
• Still-air cavity instead of argon in those same low-priority rooms
• Standard aluminium frames for retrofit-equivalent work; reserve thermally broken aluminium for new builds and full envelope renovations
• Like-for-like sizing wherever possible — resizing openings adds reframing, lining, and reinstatement cost
• Stage the work — start with the rooms that have the worst condensation or biggest single-glazed expanses (usually living areas and master bedroom), and do the rest in a second pass when budget allows

What’s almost never worth saving on: the seal quality of the IGU itself, the installer’s experience, and the flashings around the frame. A cheap window installed by someone unfamiliar with weathertight detailing will fail a lot faster than a mid-range window installed properly.

What Goes Into a Full Kitchen Renovation?

A full kitchen renovation isn’t just swapping out cabinets. It’s a multi-stage process — and each stage affects your budget. Whether you’re in Ponsonby or Papakura, here’s what a complete kitchen overhaul actually involves.

Think of it like a puzzle: every piece has to fit together properly or the whole thing suffers. Based on our experience at Superior Renovations and guidance from Auckland Council, here’s what you’re looking at — and how each stage affects your overall cost.

• • Planning and Design: This is where your vision becomes a workable plan. You’ll work with a designer — like our Senior Designer Dorothy Li — to map out the layout, workflow, and aesthetic. A 3D render helps you see the space before anything is ordered. Expect $2,000–$5,000 for professional design services in Auckland, depending on complexity. As Dorothy puts it: a well-planned kitchen saves time, money, and stress during the build.

• • Demolition and Removal: Old cabinets, benchtops, and appliances come out. In older Auckland homes, you’ll sometimes find surprises — outdated wiring being the most common. Demolition typically costs $1,500–$3,000 depending on kitchen size and condition.
  • Structural Changes: If you want open-plan, walls may need to come down. Load-bearing walls require engineering sign-off and a Building Consent — which adds $500–$2,000 in permit fees before any work starts. Check with Auckland Council early.
  • Plumbing and Electrical: Moving a sink or adding new lighting is standard in a kitchen reno — but it needs licensed professionals. Budget $2,000–$6,000. EECA guidelines apply for energy-efficient installations. Cut corners here and you’ll regret it.
  • Flooring and Wall Finishes: From tiles to timber, flooring sets the tone for the whole kitchen. In Auckland, quality materials like ceramic or hardwood run $50–$150 per m². Wall finishes and splashback tiles add another $1,000–$3,000. Our designer Alison Yu makes the point well: choosing durable flooring matters in a busy Auckland kitchen — you’ll thank yourself later.

• Cabinets and Benchtops: Cabinets are the backbone of the kitchen — $5,000–$25,000 depending on materials (laminate through to solid timber). Benchtops in granite or engineered stone range from $2,000 to $10,000.
• Appliances: A full suite — oven, fridge, dishwasher — runs $3,000–$15,000. Energy-efficient options cost more upfront but save money over time. Consumer NZ has useful guidance on reliability and value.
• Finishing Touches: Lighting, handles, and the details that pull it all together. Budget $1,000–$3,000. These are the things people notice — or notice are missing.

Timeline for a full renovation: typically 6–12 weeks for a standard Auckland project, longer if structural changes are involved.

Here’s a summary of the phases and their cost ranges:

Hidden Costs That Can Derail Your Kitchen Renovation Budget

You’re halfway through a kitchen renovation in your Mount Eden villa — the new island is taking shape — when the builder finds dodgy wiring behind the walls. Budget blown. If that sounds familiar, you’re not alone. Unexpected costs catch Auckland homeowners out more often than you’d think. Here’s what to watch for.

Drawing from our experience at Superior Renovations and guidance from Consumer NZ:

• • Structural surprises: Knocking down a load-bearing wall can add $3,000–$10,000 for structural reinforcement, per Auckland Council. Our designer Kevin Yang’s advice: always get a structural engineer’s report before touching walls. Fixing a sagging ceiling costs more than the report.

• • What’s behind the walls: Older homes in Grey Lynn or Remuera regularly turn up asbestos, outdated plumbing, or old wiring. These add $1,000–$5,000 once discovered. A pre-renovation inspection ($500–$1,000) is worth it. Build a 10–15% contingency into your budget — not as an afterthought, but from the start.
  • Cabinet costs: Budget cabinets warp and wear. Quality options run $5,000–$25,000 depending on materials. Our designer Wendy Chen is direct about this: invest in cabinets that last. They’re the heart of the kitchen and you’ll interact with them every day.
  • Appliances: A full package — induction cooktop, integrated fridge, dishwasher — can hit $3,000–$15,000, not including installation. EECA recommends energy-efficient models to offset Auckland’s rising power costs over time.

• Professional fees and consents: Design fees, contractor costs, and architect fees add $2,000–$10,000. Building Consents for structural changes add $500–$2,000. Don’t try to avoid these — unpermitted work shows up on LIM reports and causes problems at sale time.

Start with a realistic plan. Our Kitchen Cost Calculator NZ factors in everything from demolition to permits, so the numbers you’re working with reflect what Auckland kitchens actually cost.

How Much Does a Kitchen Renovation Cost in Auckland?

For a standard kitchen renovation in Auckland — new cabinets, benchtops, flooring, and plumbing and electrical work — the typical range is $19,000 to $29,000, not including appliances. Custom kitchens with premium fittings can reach $40,000 or more. Here’s how it breaks down by tier:

• • Basic ($15,000–$20,000): New laminate benchtops, standard cabinets, basic appliances. Suitable for rental properties or straightforward refreshes on a tight budget.
  • Mid-range ($20,000–$29,000): Engineered stone benchtops, custom cabinets, energy-efficient appliances. This is where most Auckland homeowners land. Our designer Cici Zou puts it well: mid-range kitchens balance style and practicality — you get a good result without overcapitalising.

• High-end ($30,000–$50,000+): Marble benchtops, solid timber cabinets, top-tier appliances. Common in suburbs like Herne Bay and St Heliers.

What drives these costs? The choices you make. Vinyl flooring over hardwood saves thousands. Moving plumbing for an island adds $2,000–$5,000. Building.govt.nz notes that keeping your existing layout is one of the most effective ways to control costs.

Real-world example: Sarah, an Epsom homeowner, chose mid-range materials but put her budget into a quartz benchtop. Total cost: $26,000 including labour and permits.

Auckland-specific factors: High tradie demand and the cost of living push prices above other NZ regions. Older homes — Devonport villas, Grey Lynn bungalows — often need additional work for outdated wiring or plumbing. EECA recommends energy-efficient fittings to offset long-term power costs, which matter in Auckland.

How to keep costs down: Think about how you actually use your kitchen. If you cook seriously, an island might be worth it. If the kitchen is mostly for quick meals, focus on functional storage upgrades rather than premium finishes. Our designer Alison Yu puts it simply: think about your kitchen daily — that’s what should guide your budget decisions.

Factors That Drive Kitchen Renovation Costs in NZ

Two kitchens in Auckland can have wildly different price tags. Here’s what actually drives the difference.

Think of your kitchen renovation like ordering coffee in Ponsonby — a flat white or a double oat milk latte with all the trimmings. Every choice adds up. Here’s what matters most:

• • Kitchen size and layout: A small 8m² kitchen in Papakura might cost $15,000. A 20m² open-plan kitchen in St Heliers could hit $35,000. Relocating a sink or adding an island adds $2,000–$5,000 in plumbing and electrical work. Dorothy Li’s advice: stick to your existing layout wherever possible. It’s the single most effective way to control cost.

• • Materials: Laminate benchtops cost $1,000–$3,000. Quartz or granite runs $5,000–$10,000. Vinyl flooring sits at $50–$80/m², hardwood or tiles at $100–$150. EECA recommends durable, energy-efficient materials — they cost more upfront and less over time.
  • Appliances: A basic package costs around $3,000. High-end smart appliances can push that to $15,000. Our designer Wendy Chen’s view: choose appliances that suit how you cook, not how you want to cook. Check Consumer NZ for reliability data before you commit.
  • Structural changes: Load-bearing wall removal costs $3,000–$10,000 plus permits at $500–$2,000, per Auckland Council. Skip the consents and you’ll face problems at sale time.
  • Labour and professional fees: Auckland tradies are busy and charge accordingly. Expect $2,000–$10,000 for skilled contractors, designers, and project management.
  • What’s behind the walls: Older Auckland homes regularly turn up plumbing or wiring that needs replacing. A pre-renovation inspection ($500) is cheap insurance against finding out mid-build.

How to prioritise: If you host regularly, invest in the island. If you’re a low-key cook, focus on durable basics and smart storage. Our Kitchen Cost Calculator NZ lets you adjust these variables and see how they affect the total in real time.

About Our Kitchen Cost Calculator

Planning a kitchen renovation in Auckland without a clear cost picture is genuinely difficult. How do you know if you’re budgeting enough for that new benchtop — or about to be caught out by plumbing costs? That’s what our Kitchen Cost Calculator NZ is for. Built specifically for Kiwi homeowners, it gives you a personalised estimate in under a minute.

We built it because renovation costs in Auckland are often opaque. You shouldn’t have to commit to a project without a realistic idea of what it’ll cost. The calculator factors in local labour rates, material costs, and your own preferences — kitchen size, benchtop material, whether you’re making structural changes. The result is a cost breakdown based on what Auckland kitchens actually cost, with a 10–15% variance to reflect the unexpected.

Why use it?

• Estimate total costs across all stages — labour, materials, design.
• See how specific choices (moving plumbing, premium appliances) affect the budget.
• Account for contingencies — particularly relevant in older Auckland homes.

As Kevin Yang, one of our designers, puts it: the calculator is like a roadmap — it shows you where your money’s going before you start.

How accurate is it? It uses average costs from our 10+ years of Auckland kitchen renovations, cross-referenced with data from Auckland Council. It assumes $5,000–$25,000 for cabinets and $2,000–$10,000 for benchtops, depending on materials. It won’t replace a detailed quote from our team — but it’s the right starting point.

What it doesn’t cover: Appliances (these vary too much) and partial renovations.

Real example: Tom, a homeowner in Mt Roskill, used the calculator for a 12m² kitchen with engineered stone benchtops and no structural changes. The result was a $24,000 estimate — which helped him prioritise custom cabinets over an island he didn’t really need.

Superior Renovations has been working on Auckland kitchens for over a decade. The calculator is a free tool that came directly from client feedback — people wanted to understand the numbers before committing to a conversation. It’s a good place to start.

Garage Conversion Cost Calculator NZ — Your Estimate in 60 Seconds

Quick answer: Get a personalised garage conversion cost estimate emailed straight to your inbox in under 60 seconds. No phone calls, no sales pitches, no waiting on a builder’s diary. Tell us your project basics, and we’ll send back a project-specific number based on real 2026 Auckland pricing.

You’re staring at the garage. The car’s parked on the drive most weeks anyway. What if that space became a teenager’s bedroom, a home office, a rental income stream, or somewhere for your mum to live closer without moving in?

The first question is always the same — what’s it actually going to cost? You’ve probably already pulled up a few ranges online. They span $30K to $180K. Useful as a wall poster. Useless for planning. Once you’ve estimated your budget, see how our garage conversion service manages the full process from consent to finished room.

What you need is a number that fits your garage. Your section. Your conversion type.

That’s what this calculator gives you.

Why a Calculator Beats a Generic “Per m²” Estimate

Most online sources will tell you a garage conversion in Auckland costs $40,000–$180,000. That’s accurate. It’s also useless for budget planning.

The range is that wide because “garage conversion” covers wildly different projects. Converting a single garage into a teenager’s bedroom on a flat section in Albany sits at the bottom. Turning a double garage into a self-contained granny flat with kitchen, bathroom, and separate entry on a leaky-era home in Glen Eden sits near the top. Both are “garage conversions in Auckland.” Both technically inside that $40K–$180K spread. Both cost vastly different amounts.

The headline range alone doesn’t tell you which one you are.

That’s where the calculator earns its keep. Instead of giving you a number that covers everyone, it asks the specific questions that move your number — type of room, size of garage, whether you need plumbing, the condition of what’s already there — and gives you a tailored estimate based on what those choices actually cost in Auckland right now.

It takes about a minute. Results land in your inbox.

What Goes Into the Estimate

The calculator works through the same variables we use when we’re pricing a real project. None of it’s guesswork — every input maps to a cost driver we’ve seen on completed Superior Renovations jobs.

Built from data across hundreds of Auckland renovations completed since 2018 — including garage conversions, granny flat builds, sleepouts, and minor dwelling additions.

Type of conversion. This is the single biggest driver. A dry-room conversion — bedroom, study, gym — sits at $40,000–$60,000. Add a bathroom and you’re at $80,000–$110,000. Full granny flat with kitchen, bathroom, and separate entry runs $120,000–$180,000. The jump isn’t linear — wet areas need plumbing, drainage connections, waterproofing, ventilation, and higher-spec fixtures.

Size of the garage. Single garages typically run 18–22m². Double garages 36–40m². A double conversion costs more in absolute terms but the per-m² rate often comes down because fixed costs (consent fees, design, structural assessment) spread across more floor area.

Foundation and floor condition. Most Auckland garages were built with a concrete slab that wasn’t designed for habitable use — no damp-proof membrane, no insulation underneath. Bringing the floor up to habitable standard means either insulating over the existing slab (loses ceiling height) or breaking out and re-pouring (adds $8,000–$15,000). Volcanic clay sections in Mt Eden or Mt Albert can complicate this further.

Insulation and weathertightness. H1 insulation requirements changed in 2023. Walls, ceiling, and floor all need to hit current R-values. Garages built before 2008 will typically need full re-insulation. Add windows and the spec gets stricter again.

Plumbing and electrical. Running new water, waste, and drainage to a detached garage is more expensive than to an attached one — sometimes $5,000–$12,000 just for the connections. Electrical needs to be brought up to current Standards and usually means a new sub-board.

Finish level. Standard GIB and vinyl, or feature timber lining and engineered flooring? Premium finishes add $10,000–$25,000 on most conversions.

What You Get in Your Inbox

A couple of minutes after you submit, you’ll receive an email with a project-specific estimate. Here’s what’s in it:

A low-to-high range based on the inputs you provided. Not a single point estimate — because no honest builder gives you one before a site visit. The range shows you where your project realistically sits.

A breakdown of the main cost categories — structural, finishes, professional fees, consents, services — so you can see where the money goes and where the biggest swings are.

Notes on what the estimate doesn’t include. Typically GST, resource consent (if triggered), development contributions for new dwellings, and any unforeseen ground or structural issues that only become visible once construction starts. We’d rather flag the limits than pretend they don’t exist.

It’s not a quote. Quotes need site visits, drawings, and detailed scope. The estimate is the layer before that — the number that tells you whether your project sits in a budget you can work with, or whether you need to rescope before going further.

If the number looks workable, the next step is usually a feasibility consultation, where we walk through your specific garage, what you’re trying to achieve, and what’s realistic on your section. That’s a separate conversation — and one you can book after you’ve seen the estimate, not before.

The Three Variables That Move Your Number the Most

If you’ve used the calculator and want to understand what drove your result, these three factors do most of the heavy lifting.

1. Whether you’re adding plumbing — 30–40% of the total. The single biggest jump in cost is the leap from dry-room conversion to wet-room conversion. Adding a bathroom alone takes a $50K project to $90K-plus. Adding a kitchenette on top pushes another $20K–$35K. If the goal is just usable floor space, a dry-room conversion gives you the best return per dollar. If you’re going self-contained, expect the budget to roughly double.

2. Condition of the existing structure — 15–30% of the total. Garages weren’t built to habitable standard. A garage with a sound slab, intact roof, good wall framing, and proximity to existing services converts faster and cheaper. A 1970s leaky-era garage with rotting bottom plates, asbestos cladding, or a cracked slab can swallow $20K–$40K in remediation before the conversion proper even starts. Worth getting a builder to assess before committing to a budget.

3. Labour and trade coordination — 35–45% of the total. Auckland trade rates currently sit at $90–$120 per hour depending on the trade. A typical 25m² conversion needs 350–600 trade hours across builder, electrician, plumber, gibstopper, and tiler. The reason fixed-price quotes look higher than charge-up isn’t margin — it’s the risk premium for guaranteeing the number. Charge-up budgets routinely blow by 15–25% on conversions because of unexpected condition issues behind the gib.

Knowing which of these three is the biggest factor on your garage tells you where to focus when you’re trying to bring the number down — or where to brace yourself if it has to stay where it is.

Convert the Garage, or Demolish and Build New?

This question matters more in 2026 than it did a year ago.

In January 2026, the government introduced the Schedule 1A Small Stand-alone Dwelling (granny flats) exemption — new dwellings up to 70m² can now be built without a building consent if they’re designed and constructed by licensed professionals and meet specific conditions. That’s a structural shift in the economics of adding a second dwelling to your property.

Here’s the awkward bit: the exemption applies to building new — not to converting existing structures. A garage conversion still triggers building consent because it changes the use of an existing building, involves structural alterations, and almost always involves plumbing and electrical work.

Which means homeowners now have a genuine choice:

Convert the existing garage. Cheaper if the garage is in good condition. Faster start. Keeps the existing footprint. Consent required. $40K–$180K depending on scope.

Demolish the garage and build a new 70m² SSAD-exempt dwelling. Higher upfront cost — roughly $200K–$280K for a turnkey dwelling. But no building consent. No consent processing delays. More floor area. Standalone status. The numbers can work out closer than they look once you factor in the consent fees and design timelines avoided.

The break-even point depends heavily on the condition of the existing garage. If it’s structurally sound with good services nearby, convert. If it’s rotten, undersized, or full of asbestos, the new-build pathway can be the cleaner answer.

The calculator gives you the conversion estimate. If you want to weigh that against a new-build SSAD option, that’s worth a feasibility conversation before you commit to either path.

Why a Calculator Beats a Generic “Per m²” Number

Most online recladding cost ranges fall into one of two camps. You’ll either see $150–$450 per square metre (the light-scope number — cladding swap on a sound home) or $1,750–$2,500 per square metre (the full-scope number — cladding plus timber remediation, joinery, insulation, the lot). Both numbers are real. They describe completely different jobs.

The reason recladding pricing is confusing isn’t that builders are hiding the number. It’s that recladding means different things depending on what your home actually needs.

A timber-framed Howick home with sound framing getting fibre cement weatherboards swapped in is a $40,000–$90,000 job. A 1990s Auckland monolithic home with hidden moisture damage, decayed framing, and joinery that needs replacing is a $250,000–$400,000+ job. Same word, very different reality.

The calculator’s job is to figure out which job you have. It asks the questions that move the number — home size, cladding type, scope — and gives you a tailored range instead of a generic one.

It takes about a minute. Results land in your inbox.

What Goes Into the Estimate

The calculator works through the same variables we use when we’re pricing a real reclad. None of it’s guesswork — every input maps to a cost driver we’ve seen on completed Superior Renovations recladding jobs.

Home size in square metres. The starting point. Be honest about your full floor area, including upper levels if you’re two-storey — the recladding cost scales with the exterior wall area, which is roughly proportional to floor area.

Current cladding type. Timber weatherboard, monolithic plaster (direct-fix), brick veneer, fibre cement — each comes off differently and reveals different conditions underneath. Monolithic homes from the late 1990s and early 2000s are the most likely to need full remediation, which pushes the budget up materially.

Target cladding material. Going to fibre cement (James Hardie Linea, for example) at around $150–$250/m² is the most common choice in 2026. Cedar or premium weatherboard sits at $250–$350/m². Metal longrun, brick veneer, or schist can push past $400/m² installed.

Scope of remediation. This is the big swing factor. A like-for-like swap on a sound home is one thing. A reclad that includes full timber remediation, all new joinery, insulation upgrade to current H1 standards, and interior reinstatement is another job entirely — and usually 4–6× the cost per square metre.

Access and site conditions. Scaffolding around a two-storey home on a tight section in Grey Lynn costs more than a single-storey on a flat site in Flat Bush. Shrink-wrapping (weather protection during the build) is essential for Auckland weather and adds to the scaffold spend.

You don’t need to know exact specs going in. The calculator gives you a sensible default for each input — your job is to tell it what you’re roughly planning.

What You Get in Your Inbox

A couple of minutes after you submit, you’ll receive an email with a project-specific estimate. Here’s what’s in it:

A low-to-high range based on your inputs. Not a single point estimate — because no honest builder gives you one before site visit and weathertightness assessment. The range shows where your project realistically sits given what you’ve told us.

A breakdown of the main cost categories — cladding materials, labour, scaffolding and weather protection, professional fees (architectural, engineering, consent), and an allowance for remediation if relevant. Helps you see where the biggest swings are.

Notes on what the estimate doesn’t include. Typically GST, interior finishes if your scope extends inside, and any unforeseen structural or moisture damage that only becomes visible once the cladding is off. We’d rather flag the limits than pretend they don’t exist.

It’s not a quote. Recladding quotes need a weathertightness assessment, design drawings, and a detailed schedule of works. The estimate is the layer before that — the number that tells you whether your project sits in a budget you can work with, or whether you need to rescope before going further.

If the number looks workable, the next step is usually a feasibility assessment, where we walk through your specific property, what you’re trying to achieve, and what’s realistic on your home. That’s a separate conversation — and one you can book after you’ve seen the estimate.

The Three Variables That Move Your Number the Most

If you’ve used the calculator and want to understand what drove your result, these three factors do most of the heavy lifting on recladding budgets.

1. Scope — light reclad vs. full remediation. Single biggest factor by a long way. A like-for-like cladding swap on a sound timber-framed home runs $150–$450/m² and usually lands between $40,000–$90,000 total. A full leaky-home reclad with timber remediation, new joinery, insulation, and interior reinstatement runs $1,750–$2,500/m² and lands between $250,000–$400,000+ for a typical 180m² home. Same home, vastly different jobs. The calculator’s main work is figuring out which one you’re looking at.

2. Cladding material chosen. Fibre cement is the most common 2026 choice — durable, fits the drained cavity requirement under E2/AS1, comes in at the bottom of the material cost range ($150–$250/m² installed). Premium options like cedar weatherboard ($250–$350/m²), brick veneer ($350–$500/m²), or metal longrun for coastal sites all push the per-m² rate up. Material choice alone can swing a 180m² project by $30,000–$50,000.

3. Building consent and professional fees. Almost every reclad triggers building consent, and many trigger a fresh weathertightness review under E2/AS1. Architectural and engineering fees typically run $8,000–$15,000 for a standard reclad, $15,000–$25,000 for a complex one. Council fees add $3,000–$8,000. None of this scales with home size in a clean way, so smaller homes get hit harder on a per-m² basis.

Knowing which of these three is the biggest factor on your project tells you where the budget can flex — and where it can’t.

A Note on Building Consent

Almost every recladding project in Auckland needs building consent. The rule isn’t whether you’re swapping a small section — it’s whether the work affects weathertightness, fire safety, or structural integrity. Recladding usually affects all three, which is why Building Performance and Auckland Council treat it as consented work.

The exception: a true like-for-like replacement (same material, same fixing method, same building envelope) may not need consent. That’s rare in practice — most reclads change the cladding system, add a cavity, or upgrade insulation, all of which trigger consent.

The calculator includes a typical consent fee range in the estimate, but for accuracy on your specific project, your designer or LBP builder will give you the exact figure after they’ve assessed scope.
