Supplying Your Own Kitchen Appliances: What to Check
The oven is on special, the fridge you want is in stock, and the retailer will deliver next week. Before you pay, know this: supplying your own kitchen appliances is legal, it's common, and the renovation company should be happy to install them, but the order you make decisions in matters more than the price you pay.
Here's the short answer. Choose your appliances before anyone draws the cabinets, give your designer the model numbers and installation manuals, have them delivered and checked before fit-off week, and put in writing who is responsible for the appliance and who is responsible for installing it. Get those four things right and buying your own is one of the easiest parts of a kitchen renovation. Get them wrong and you can end up with a 900mm cooktop over a 600mm oven cavity, a dishwasher door that hits the island, or a faulty fridge nobody thinks is their problem.
We're Superior Renovations, and when clients ask whether they can supply their own fixtures and fittings, our answer is yes. This guide covers what we check when they do, why, and which New Zealand rules decide who stands behind what.
Where the Saving Sits When You Buy Your Own
Our guide to which kitchen jobs NZ law lets you do yourself sorts the work into two piles: carpentry, finishes and a short electrical list that a capable homeowner can take on, and plumbing, gas and structural work that stays with licensed people. Buying the products sits outside both piles. Choosing and paying for an oven isn't building work, gasfitting or plumbing, so there's no licence involved.
That's why homeowners gravitate to it. It feels like the one saving with no catch. The catch is real, though. It's just not a legal one.
What you gain
You get full control of brand, model and timing. If a retailer has a sale, a trade-in offer or a bundle deal, you can take it. If you've owned a particular brand of dishwasher for fifteen years and trust it, you don't have to argue for it. Some people just like the research.
What you take on
You take on sizing, delivery, inspection and the fault conversation if something arrives broken or fails early. Don't assume the retail price beats what the renovation company would have paid. Our own FAQ is upfront that most clients end up using our supplier network, because we get trade pricing, we manage delivery, and sorting out a faulty product is easier when there's a direct supplier relationship.
Get both prices before you decide. Sometimes the promotion wins. Sometimes it doesn't.
For a lot of Auckland households it's still worth doing. The rest of this guide is about doing it without creating a problem three weeks into the job.
Choose the Appliances Before Anyone Draws a Cabinet
This is the rule that matters most, and it's the easiest one to break. Appliances set the dimensions of the kitchen, not the other way round. Oven cavities, cooktop cut-outs, integrated fridge housings, dishwasher panels and rangehood canopies are all sized off the specific model. Change the model after the cabinets are drawn and something gets redrawn, remade or cut on site.
When you come in for a design consultation, we ask you to bring any specific appliances you want, with model numbers. That's not paperwork for its own sake. It's what lets the designer size the carcasses correctly the first time.
The worst version of this is when someone buys a beautiful freestanding cooker after we've drawn a kitchen around a 600mm wall oven. Nothing's wrong with either appliance, they just don't belong in the same kitchen. I'd rather have your model numbers on day one, even if you change your mind twice, than find out at install.

The installation manual is the real specification
Every built-in appliance ships with an installation manual that sets its cut-out size, clearances and ventilation requirements. Download the manual before you buy, not after it arrives. Most manufacturers publish them on their websites. Your designer and your trades work to that document, and if it conflicts with a generic rule of thumb, the manual wins. Our kitchen planning measurements guide covers the standard widths, walkway clearances and cooktop-to-rangehood distances we start from, and it repeats the same caveat: always check the appliance manual.
Integrated models lock the cabinetry
A fully integrated dishwasher or fridge takes a cabinet door on its front, so the cabinetmaker needs the exact door-mounting and hinge details for that model. Pick an integrated model and you've made a joinery decision as well as an appliance decision. The Scandi-style kitchen on our Mellons Bay full-home renovation has a concealed dishwasher behind a cabinet front, next to hidden bins and pull-out condiment drawers. A layout like that is drawn around the dishwasher's mounting details, not adjusted to fit them later.
If you're getting several quotes, send every company the same appliance list. Little Giant Interiors on comparing kitchen quotes line by line makes the point well: appliances usually sit outside the cabinetry quote, and a quote built around one oven can't be fairly compared with a quote built around another.
Power, gas and water are sized off the model too
An induction cooktop, a wall oven and a plumbed fridge each have their own supply requirements, and those come from the spec sheet. Your electrician, plumber and gasfitter need the model details before the first-fix visit, while the walls are still open. That's also where the legal line from our DIY guide comes back in: you can choose the cooktop, but connecting it to gas, adding a new circuit or plumbing a new fridge position is licensed work. That holds whether the hob runs on reticulated gas or on LPG bottles outside a Titirangi kitchen wall. Moving the sink or adding a plumbing fixture can also bring a building consent into play, so if your appliance choice changes the layout, check with Auckland Council or a Licensed Building Practitioner before you commit.
Reading the Labels: What the Energy Rating Label Covers and What It Doesn't
When you shop for yourself, the labels on the appliance are most of the independent information you'll get. They're useful, but only for the products they cover.
Which appliances carry an Energy Rating Label
The Energy Efficiency (Energy Using Products) Regulations 2002, which EECA administers, require an Energy Rating Label on household fridges, freezers and fridge-freezers, clothes washers, clothes dryers, dishwashers, heat pumps, televisions and computer monitors when they're offered for sale. Ovens, cooktops and rangehoods aren't on that list, so for the three appliances that define most kitchens, there's no star rating to compare. You're relying on the spec sheet, reviews and the retailer's advice.
For the appliances that are labelled, EECA's guidance is to compare stars between products of the same size and type, and to use the annual energy figure to estimate running cost. Its worked example: an appliance using 180 kWh a year at 30c per kWh costs roughly $54 a year to run. The dishwasher figure is based on 365 uses a year, so if you run yours every second day, roughly halve it. Dishwashers and clothes washers also carry a Water Efficiency Label.
Display models and online listings
EECA notes that a retailer's website may not show the label itself, but the star rating and energy consumption should be in the product specifications. If a floor model has no label, ask. Second-hand appliances don't have to carry one at all.
Tapware has its own labels and its own trap
Taps and showerheads carry WELS water-efficiency stars. The bigger issue for owner-supplied tapware is pressure. A mixer designed for mains pressure can deliver a weak trickle on a low-pressure system, and some older character homes, a Grey Lynn villa with its original cylinder for example, are still low-pressure or unequal-pressure. We cover pressure, WELS stars and the low-lead rules in detail in our guide to choosing bathroom tapware that suits your water pressure. Ask your plumber to confirm the system before you buy.
Who Stands Behind What When You Buy It Yourself
This is the part the retailer brochures and most builder websites skip. When you supply the appliance and someone else installs it, there are two separate things that could go wrong, and New Zealand law treats them differently. This is a general explanation, not legal advice. For a specific dispute, talk to Consumer NZ, a community law centre or a lawyer.
The appliance: the retailer, then the manufacturer
Under section 6 of the Consumer Guarantees Act 1993, goods supplied to a consumer come with a guarantee of acceptable quality. Section 7 defines that as fit for their common purposes, acceptable in appearance and finish, free from minor defects, safe and durable, judged against things like the price and what was said about them. If the oven you bought is faulty, your claim runs against the retailer who sold it, and the Act can also give you rights against the manufacturer. Under section 18 you can require the supplier to fix a failure that can be remedied within a reasonable time. Those rights sit with you as the buyer, not with your builder.
The installation: the installer
The same Act guarantees that services supplied to a consumer are carried out with reasonable care and skill (section 28). For residential building work, the Building Act 2004 adds implied warranties in section 362I, including that the work will be carried out in a proper and competent manner and with reasonable care and skill. Section 362I(2) says those warranties apply despite anything to the contrary in the contract, so they can't be signed away.
There's also a 12-month window. Under section 362Q, you can notify the building contractor of a defect within 12 months of completion and they must remedy it within a reasonable time. Section 362S, though, says the contractor isn't liable for a defect to the extent it's caused by an act or omission, including accidental damage, by someone who isn't the contractor, a subcontractor or a person they're responsible for. Damage that happens while an appliance is in your hands may sit outside the installer's warranty, and a fault in the appliance itself is a matter for the retailer.
Why the split has to be written down
Section 362I(1)(b) warrants that building products "to be supplied for use in the building work" will be suitable for their purpose. The Act doesn't spell out how that applies when the owner supplied the product, and you don't want to find out in a dispute. So agree it at quoting stage and put it in the contract, in plain words: which items you're supplying, who takes delivery, who checks them, and that the installer is responsible for installing to the manufacturer's instructions.
We're open about our side. Superior Renovations provides a 12-month workmanship warranty and passes on the trade and product warranties at handover. Our published FAQ also says plainly that we can't warranty work completed by others. Installing your appliance is our work. The appliance itself is covered by your purchase.
From Checkout to Fit-Off: Delivery, Storage and Install Week
Once the appliance is paid for, the risk moves to timing and handling.
Deliver before fit-off week, not during it
Have your appliances on site before the week they're due to go in. Our kitchen renovation stages guide suggests at least a week before fit-off, and tells people not to assume courier timelines will cooperate. A missing oven on install day doesn't just delay the oven. The electrician's connection visit, the benchtop cut-out check and the final clean all move with it.
Let the project manager know the delivery date at the planning stage. That's what our FAQ asks for, so we can schedule around it.
Open the boxes when they arrive
Check every appliance against the order: model number, colour, finish, and any dents or scratches. A fault found on delivery day is a simple conversation with the retailer. The same fault found six weeks later, after the appliance has been sitting beside a live building site, is a harder one. Keep the receipts, manuals and warranty cards together, because you'll hand them to the trades and then keep them for the life of the kitchen.
Store them somewhere clean and dry
A renovation produces dust, and a kitchen strip-out usually happens in the middle of the house. The garage is the usual answer, well away from where tradespeople are cutting. Leave the packaging on until install. Agree in writing who's responsible for items stored on site, because that's exactly the kind of gap section 362S leaves open.
Watch for discontinued models
Appliance ranges turn over. If you choose a model at design stage and don't buy it until months later, check it's still available before the cabinets go into production. If it has been replaced, get the new model's manual to the designer straight away. A similar-looking replacement can have a different cut-out.
What it does to the budget
Our published figure for a mid-range Auckland kitchen renovation is $26,000–$35,000 plus GST for a 10–12m² kitchen with custom cabinets, stone benchtops and quality appliances. Appliances are inside that band, so if you're supplying your own, the quote should take them out. Compare like with like: our price without appliances plus your retail price, against our price with them. You can run your kitchen through our cost calculator first to see where your scope lands before you start shopping.
The Bathroom Version: Tapware, Toilets and Vanities
The same logic applies in the bathroom, with one change: nearly everything you might buy connects to water. You can buy the mixer, the toilet suite and the vanity yourself. Fitting them is sanitary plumbing, and that stays with a licensed plumber. Our guide to the bathroom side of the DIY rules sets out exactly where that line falls.
With bathrooms, the thing I check first is whether what you've bought will actually work in your house. The pressure, the waste position, whether the vanity drawers clear the trap. I'd love to see it before it's bought. If it's already bought, bring the spec sheet and we'll design around it.

Wall-hung toilets and in-wall cisterns need their frame in the wall at framing stage, so the model has to be fixed well before tiling. Shower mixers with an in-wall body are the same. Anything that goes inside the wall has to be on site before the wall is closed, which is much earlier than most people expect.
If you'd rather see products side by side before deciding, you can browse and compare options in person at our showroom at 16B Link Drive, Wairau Valley, and our design team can talk you through what suits your house.
Supplying Your Own Kitchen Appliances: The Checklist
- Pick the appliances before cabinet design starts. Bring model numbers to the first consultation.
- Download every installation manual and send it to the designer.
- Send the same appliance list to every company quoting.
- Get a like-for-like price: the quote with appliances, and the quote without plus your retail price.
- Give model details to the electrician, plumber and gasfitter before first fix.
- Write the split into the contract: what you supply, who receives it, who installs it.
- Deliver at least a week before fit-off. Open and check everything on arrival.
- Store it clean, dry and away from the work area. Agree who's responsible while it's on site.
- Keep receipts, manuals and warranty cards together.
Frequently Asked Questions
Can I supply my own appliances for a kitchen renovation in NZ?
Yes. Buying appliances isn't regulated work, so there's no licence involved, and Superior Renovations will install owner-supplied items at the right stage. Choose them before the cabinets are designed, give the designer the model numbers, and tell the project manager the delivery date. Connecting gas, new circuits and new plumbing positions still needs licensed trades.
Who do I claim against if an oven I bought myself is faulty?
The retailer that sold it. Under the Consumer Guarantees Act 1993, goods must be of acceptable quality, and your right to have a fault fixed sits with the supplier, with possible rights against the manufacturer too. The installer is responsible for installing it with reasonable care and skill, which is a separate question from whether the appliance itself works.
Do ovens and cooktops have an Energy Rating Label in New Zealand?
No. EECA's labelling requirement covers fridges and freezers, dishwashers, clothes washers and dryers, heat pumps, televisions and computer monitors. Ovens, cooktops and rangehoods aren't on the list, so compare them using the manufacturer's specifications. Dishwashers carry both an Energy Rating Label and a Water Efficiency Label.
When should my own appliances be delivered during a renovation?
At least a week before fit-off, and earlier for anything that goes inside a wall, such as an in-wall cistern frame or shower mixer body. Open each box on arrival and check the model and condition. Store appliances somewhere clean and dry, away from the work area, until install day.
Buying your own appliances works well when the decisions happen in the right order: model first, cabinets second, delivery before install, and the responsibilities written down. If you'd like help getting that sequence right, book a free consultation and bring your appliance list with model numbers.
