Quick answer
Most NZ kitchen warranties cover cabinetry, hinges and benchtops against manufacturing faults, but exclude poor installation, normal wear and water damage. A single supply-and-install contract, like MTN Kitchens runs in Auckland, makes one party accountable for both product and workmanship.
Key points
- A kitchen has three or four separate warranties (cabinetry, hardware, benchtop, appliances) that rarely share a start date or length, and disputes live in the gaps between them.
- Product warranties cover the goods only, not the labour to pull a unit out and refit it, which is usually most of the cost of a callback.
- The Consumer Guarantees Act and Building Act sit over the paper, but the CGA can be contracted out of on developer and commercial jobs, so your real protection is the contract and the company behind it.
- Splitting supply from install to chase a cheaper fitter is the single biggest cause of unowned defects during the builder's defects period.
- On volume work, the warranty that earns its keep is one number to ring and the same crew coming back, not the longest number on paper.
Four warranties, one number to call.
Nobody reads the warranty until a door drops eighteen months into a tenancy. A benchtop joint lifts over the dishwasher. A soft-close hinge starts sagging and the door catches the next one along. For a homeowner that is one annoying Saturday. For a developer who put the same kitchen into 40 terraced units in Flat Bush, it is a run of callbacks landing right in the middle of your defects period, with the trade who fitted them already three jobs down the road. Sorting out what is actually covered before you sign the supply contract is the cheap part. Finding out afterwards is the expensive one.
There is no single kitchen warranty in New Zealand. You get a stack of separate cover from different parties, all running for different lengths, and every dispute we have ever seen sits in a gap between two of them. On top of that stack sits the Consumer Guarantees Act and the Building Act, which override a lot of the fine print whether the supplier likes it or not. Here is how the whole thing works, where the gaps open up, and the questions worth nailing down before you commit, especially on volume work where one specification gets repeated across dozens of dwellings.
Three or four warranties, not one
A standard kitchen carries at least three separate warranties that almost never share a start date or a length. The cabinetry and the joinery build is covered by whoever made it, against faulty materials and workmanship. The hardware is its own thing again. Blum and Hettich hinges and runners often carry far longer manufacturer cover than the cabinets they are screwed into, sometimes a lifetime mechanical guarantee on the runner itself. Benchtops are separate, and the terms swing hard depending on whether you specced laminate, engineered stone or a natural stone. If appliances are in the deal, they sit under brand cover entirely and have nothing to do with the joiner.
So when a supplier tells you the kitchen comes with a warranty, you have learnt almost nothing. Get it broken out by component, each with a start date and a claim path. Who do you ring, what do they need from you, and how fast do they turn up. A single sheet that says twelve months on everything is a red flag, not a reassurance, because it means somebody has flattened four different sets of terms into a number that suits them.
| Component | Who stands behind it | Typical length | The catch |
|---|---|---|---|
| Cabinetry and carcass | The joiner who built it | Several years | Voided by water ingress and third-party install faults |
| Hardware (hinges, runners) | Brand (Blum, Hettich) | Long, sometimes mechanical lifetime | Mechanical failure only, not abuse or misadjustment |
| Laminate benchtop | Fabricator or sheet maker | Straightforward, shorter | No cover for knife marks, heat or water sitting on joins |
| Engineered stone benchtop | Stone brand or fabricator | A decade or more | Conditional on approved fabricator, sealing and care |
| Appliances | Appliance brand | Brand terms, varies | Nothing to do with the joiner; chase the brand |
On a subdivision those start dates matter twice over, because they have to line up against your own Building Act defects obligations to the eventual owner or body corporate on a unit-title development. If your supplier's cover starts the day the carcasses leave their workshop, and those units sit shrink-wrapped in a container for four months waiting on the build, you have quietly burned a third of the warranty before a single drawer has been opened.
What is covered and what is not
A real manufacturing warranty covers defects in materials and workmanship under normal use. Delamination that was not caused by water sitting on a raw edge. A hinge that fails on its own. A carcass built out of square. A 2-pac door that crazes or yellows when it had no business doing so. Those are the maker's problem and they should fix them without a fight.
What it will not cover is the daily-wear stuff and the someone-else stuff: chips and scratches, knife marks on a laminate top, water getting in around a sink that was sealed badly by another trade, movement as the building settles, heat damage from a pot straight off the element, and any fault that traces back to the install. That last one is where supply-only arrangements fall over. The joiner who supplied flat-pack or finished units points at the installer; the installer points at the product. The defect is real, the developer is wearing it, and nobody will put their name to the fix. That single gap is the best argument for keeping supply and install on one contract. It is the same reason many builders weigh up why they outsource kitchens in the first place rather than fitting bought-in units with their own chippie.
The exclusions that catch people out
Read the void clauses, because that is where the real boundaries sit, not the headline number. The usual suspects: misuse, lack of normal maintenance, exposure to standing water or steam, modifications by another trade, and the big one on stone tops, sealing and care. Some engineered stone warranties are conditional on the slab being handled and installed by an approved fabricator. Hand the top to a cheaper benchtop subbie to shave a few hundred dollars and you can void the cover on the most expensive component in the room.
- Cabinetry and carcass: defects in materials and the build, under normal household use
- Doors and finishes: delamination, 2-pac crazing or peeling, melteca lifting at the edges where it was not caused by water
- Hardware: hinges, runners and lift systems failing mechanically on their own
- Benchtops: manufacturing defects, but with care, sealing and fabricator conditions attached, especially on stone
- Not covered anywhere: wear and tear, impact damage, heat, water ingress, third-party modifications, and faults caused by a separate installer
The law sitting over the top of the paper
A written warranty is a promise from the supplier. It is not the only protection you have, and on residential work it is often not the strongest one. The Consumer Guarantees Act says goods and services have to be fit for purpose and of acceptable quality, and that runs underneath any warranty document. A supplier cannot write a clause that signs the CGA away on a consumer job. So even when the paper warranty has expired, a kitchen that fails well before a reasonable person would expect it to can still be the supplier's problem.
The catch is that the CGA gets murky on commercial and developer contracts, where the parties can agree to contract out of it in writing. That is exactly why developers and commercial fit-out clients should not lean on consumer law as their backstop. Your protection on a 30-unit job is the contract you sign and the company standing behind it, not a statute written for the family buying one kitchen.
The Building Act adds the other layer. The implied warranties under the Act, and the 12-month defects period most build contracts carry, mean the head builder is on the hook to the eventual owner regardless of what the kitchen subbie's warranty says. If your kitchen supplier's cover is shorter or narrower than your obligation to the buyer, that gap does not disappear. You just inherit it. Code Compliance Certificate sign-off does not close it either, because CCC is about the building consent being met, not about whether a drawer front falls off in year two. This is also where the kitchen overlaps with broader commercial kitchen compliance in NZ if your fit-out is anything other than residential.
Why one contract for supply and install changes the maths
A product warranty covers the goods and nothing else. It does not pay the labour to pull the unit out, the make-good around it, or the damage if something lets go over a finished floor. That is the work, and the work is most of the cost. Replacing a failed engineered stone top is not just a new slab; it is a templater back on site, the old top broken out, a plumber to disconnect and reconnect, and a sparky if the cooktop sits in it. The slab might be the cheap part of that callback.
When the same business builds the kitchen and installs it, the line of responsibility is clean. If it fails inside the warranty period and it is genuinely a defect, the same outfit comes back and fixes product and labour. No quote, no argument about whose fault it was, no three weeks of emails between a joiner in one suburb and a fitter in another while the tenant cooks around a propped-up door.
On a 40-unit job, the warranty that earns its keep is not the longest one on paper. It is having one number to ring when a door drops, and knowing the same crew that fitted it turns up to sort it. We have been doing it that way for 23 years. - MTN Kitchens, East Tamaki
That is the only way we run it. Kitchens are built in our own East Tamaki workshop and installed by our own crews, who are Site Safe qualified. No handoff to a third-party fitter on site means no seam for a defect to disappear into. One contract, one invoice, one party answering for both halves of the job. We work as the head-contractor kitchen supplier to Spencer Henshaw on exactly that basis, and it is the reason the relationship has lasted.
A worked example: 24 townhouses in Flat Bush
Take a real shape of job. A developer is building 24 two-storey townhouses across a staged subdivision in Flat Bush, unit-titled, sold off the plans, with a 10-year master build guarantee and the standard 12-month builder's defects period on top. The kitchens are identical: melteca carcasses, 2-pac doors in a single colour, a 20mm engineered stone benchtop, Blum hardware, a scullery in the larger plans. The developer wants one kitchen spec across all 24 so the show home and the last unit match.
Sequencing the warranty against the build
The mistake here is letting all 24 kitchens get measured, built and delivered in one hit to lock a price, then sit in storage while the build runs through three stages over eight or nine months. By the time the last block is lined, the stage-one kitchens have chewed eight or nine months off a warranty nobody has used yet. We sequence the opposite way. Built to the locked drawings, but delivered and installed stage by stage as each block reaches lock-up, so the warranty clock starts close to when the owner actually takes the keys. The price is held across the whole run; the install follows the construction programme. Getting that right is mostly a matter of kitchen lead times and your construction programme rather than warranty paperwork.
Where the money moves
On a job like this the kitchen line is typically somewhere in the low-to-mid five figures per unit plus GST for the cabinetry and a stone top, before appliances, and the levers are obvious once you see them. Dropping from engineered stone to a high-pressure laminate benchtop takes a meaningful chunk out of each unit and multiplies hard across 24. Moving from 2-pac to a quality melteca door front is the next biggest lever. Cutting the scullery, simplifying the hardware, standardising cabinet sizes so there is less custom cutting, all of it adds up over a volume run. If you are weighing those benchtop options, the trade-offs are laid out properly in laminate vs stone benchtops: cost vs value. The danger is chasing the per-unit saving by splitting supply from install to grab a cheaper fitter, because that is the move that opens the warranty gap you will pay for during the defects period.
Twelve months in, a runner fails in unit nine. One call. The same crew that fitted it comes back, swaps the runner under the hardware warranty, and is gone the same morning. No three-way standoff, no labour quote, no chasing a fitter who has moved on to a job in Drury. That is the whole point of the structure, and it is invisible right up until the day you need it. Good soft-close and drawer detailing reduces those callbacks in the first place, which is the cheaper end of the same problem.
A claim you split, or one you don't make.
Laminate, engineered stone and natural stone: the warranty isn't the same
Benchtop cover is the part people assume is uniform and it is the part that varies most. Laminate is the workhorse on rentals and volume residential. The warranty is straightforward and the failures are predictable: edge lift where water has been allowed to sit, and swelling on a substrate that got wet. Keep water off the joins and a laminate top earns its keep for years, but no warranty on earth covers a knife mark or a hot pot.
Engineered stone carries longer headline warranties, often a decade or more, but they come loaded with conditions: approved fabricator, correct sealing where required, no abuse with heat. Natural stone is its own animal again, because it is a natural product. Variation in colour and veining is a feature, not a defect, and the warranty will say so in plain terms. Etching from an acid spill on a marble top is on you, not the supplier. The honest version of this conversation, which is the one worth having before you spec, is that the longer warranty on stone is real but conditional, and the conditions are where claims get knocked back.
What goes wrong
The failures we get called to fix almost never come down to a bad cabinet. They come down to how the deal was structured. Supply-only is the headline offender. A developer buys finished units cheap from one outfit and has the builder's chippie hang them to save on install. Six months later a door is binding and a join has opened, and nobody owns it. The joiner says it was fitted wrong; the builder says the product was off. Both might even be a little bit right. The developer pays to fix it twice over while everyone protects their own position.
The second one is timing. Kitchens delivered too early and stored badly on a wet site, then installed before the slab and the linings have dried out, so the carcasses take up moisture they were never meant to see. The warranty excludes water damage, the supplier is technically right, and you are still wearing it. The third is the flattened warranty: a single number with no breakdown, no transfer clause, and no named response time, which means when you sell the units the cover does not follow the title and your buyer has nothing.
- Splitting supply and install to chase a cheaper fitter, then losing the install half of any claim
- Nobody asked when the clock starts, so it started the day the units left the workshop
- No transfer clause, so the warranty does not pass to the homeowner or body corporate at sale
- Mixed specs across a development because nobody locked the drawings before the first unit went in
- Using a non-approved fabricator on stone tops and voiding the most expensive warranty in the room
- No named callback response time, so 'warranted' means nothing when a tenant is waiting
Questions to ask before you sign
Before you commit to a kitchen supplier on a volume job, get these answered in writing. Woolly answers now reliably predict woolly support during the defects period. If a supplier cannot give you a clean breakdown, that tells you how the callbacks will go. The same discipline that keeps a warranty honest is what keeps the kitchen spec consistent across 30-plus units in the first place.
- How long is the cabinetry and workmanship warranty, and exactly what voids it?
- Is the install warranted as well as the product, and is the installer insured and Site Safe qualified?
- What are the separate benchtop and hardware terms, and who handles those claims?
- Does cover start at supply, at install, or at practical completion?
- Is the warranty transferable to the homeowner or body corporate, and does it survive sale?
- What is the callback response time during the build defects period?
- On repeat work, how do you hold the same specification across every unit?
That last question matters more than it looks. A warranty is easier to honour, and callbacks are rarer, when every kitchen is built to the same drawings and the same tolerances instead of being improvised dwelling by dwelling on a wet site in Papakura. Consistency is not a luxury on a volume job; it is what keeps the defects period quiet.
The claim you never make
The best warranty outcome is the one that never gets used, and that comes from the build, not the paperwork. Volume kitchens built to one locked specification in a controlled workshop simply fail less than kitchens thrown together ad hoc across a site. Square carcasses, consistent edge sealing, the same hardware torqued the same way, benchtops templated to drawings rather than measured off a rough wall in the rain. The defects that trigger claims mostly come from variation, and a workshop kills variation. It is the same logic behind how kitchens are quality-checked at every stage before they ever leave the floor.
Over 23 years we have installed more than 2,000 kitchens, and at 10-plus a week we run to the construction programme so units land when the build is ready, with the same 2-pac or melteca finish, the same hardware and the same benchtop in every dwelling. A single install crew finishes a kitchen in five to seven days. Trade and wholesale pricing, with no showroom markup, keeps that consistency affordable across the whole project rather than just the show home in Hobsonville Point. The warranty is the safety net. The workshop is what keeps you off it.
Frequently asked questions
How long should a kitchen warranty last in NZ?
There is no legal minimum on the warranty document, which is why they vary so much: cabinetry runs several years, hardware from the major brands often longer, and stone benchtops a decade or more with conditions attached. The length matters less than what it covers and whether the install is in it, and the Consumer Guarantees Act sits underneath all of it for residential buyers.
Does a kitchen warranty transfer to the next owner?
Only if the document says so, and plenty do not. On a development this is the clause that bites you, because the cover needs to pass to each new owner or the body corporate at settlement, so get transferability in writing before you sign rather than after the first callback.
Is a supply-only kitchen cheaper than supply and install?
On the invoice, sometimes; across the life of the job, rarely, once you count the callbacks. The saving from a cheaper separate fitter is invisible until the first defect, when the install half of any claim has no owner, whereas supply-and-install on one contract means one party answers for product and labour together.
Who is liable if a kitchen fails during the builder's defects period?
The head builder carries the obligation to the owner under the build contract and the Building Act, whatever the kitchen subbie's warranty says. If the supplier's cover is shorter or narrower than that obligation, the builder or developer absorbs the difference, which is why you want the install warranted to match or beat your defects exposure.
Does Code Compliance Certificate sign-off mean the kitchen is warranted?
No. CCC confirms the building work met the building consent and says nothing about whether a hinge fails in year two or a benchtop join lifts. The kitchen warranty and the install responsibility are entirely separate from CCC, and treating the certificate as cover is a common and expensive misread on subdivision work.
