Quick answer
Settle one thing before you spec a cabinet: which wall the sink, waste and rangehood duct stay on. In a Point Chevalier bungalow the rear wall is the one your extension demolishes, so any service hung on it gets ripped out in five years. Put them on a wall that exists in both plans, usually a side wall near the existing gully trap. Then buy standard-module carcasses you can re-front rather than replace, and keep the island free of plumbing so it can be unbolted and moved. The benchtop you buy twice regardless. Done that way, stage two is a re-front and a new top, not a skip.
Key points
- The rear wall of a Point Chevalier bungalow is the wall your extension knocks out, so a sink or duct on it is money on a five-year timer.
- MBIE's guidance treats shifting a gully trap a short distance to serve a sink moved to an adjacent wall as a minor alteration to drains.
- Past ten metres a branch drain picks up venting under Building Code clause G13, so the sink's wall quietly decides your consent path.
- Melteca carcasses and doors come off the same panel, so boxes bored on the 32mm system take new fronts without being replaced.
- The benchtop is templated to the installed cabinets and never survives a layout change, so laminate stage one and save the stone.
The wall you keep decides what you buy twice.
A 1920s California bungalow off Point Chevalier Road. Kitchen at the back, sink under the window looking at the lawn, no dishwasher, a pantry that used to be a porch. Two kids, and a plan: fix the kitchen now, open the back of the house up in five years once the mortgage lets them breathe. They ring three suppliers. All three price a kitchen for the house as it stands today, because that is the house they can measure. That is the mistake, and it costs them a second kitchen.
Point Chevalier sits on a peninsula five kilometres west of the city centre, north of State Highway 16, and its housing is predominantly 1920s California bungalows and 1930s and 1940s houses, with Waterview immediately south much the same. That means one floor plan repeated street after street: rooms off a hall, kitchen at the rear, one drain run out the back, and a rear wall that is the obvious thing to remove. The same logic runs through the bungalow belt in Mount Eden and Sandringham. What follows assumes the extension is real and needs consent, which a rear addition almost certainly will. Confirm anything regulatory with Auckland Council and an LBP.
The wall that decides everything
Draw two plans: the one you are building now, and a rough one of the house you want in five years. A pencil sketch showing where the new rear wall lands is enough. Put one over the other. Any wall in the same place on both is a survivor. Everything else is a demolition zone with a kitchen bolted to it.
In a Point Chevalier bungalow the survivors are usually the boundary-side wall and the wall onto the hall. The rear wall is not one. Removing it is the entire point of the extension. So the wall with the window in it, the wall your sink has sat under since the trams ran to Coyle Park, is the one wall you must not put services on. You lose the view over the sink for five years, and stage one looks like a compromise. It is one. A deliberate one, and the difference between one kitchen and two.
Where the drain already is
Services do not move for free, and in Auckland's older stock they do not move quietly. A 1920s bungalow was drained to a gully trap outside the kitchen wall, and everything downstream of it was laid once, ninety-odd years ago, and left alone since. That trap is the most important fixed point in your staged plan, and almost nobody looks at it before choosing a layout. The rules are more generous than most expect. Schedule 1 of the Building Act exempts minor alteration to drains for a dwelling, and MBIE's own worked example is close to this job: a plumber relocates the kitchen sink to an adjacent wall, and the gully trap shifts a short distance to take the discharge from the repositioned waste pipe. A separate exemption covers alteration to existing sanitary plumbing, provided the fixture count does not increase and no specified system is affected. Both need an authorised person under the Plumbers, Gasfitters, and Drainlayers Act 2006.
The generosity runs out fast. The same guidance gives an example of a branch drain extended by sixteen metres and says consent is required, because past ten metres the drain comes under venting requirements in clause G13, foul water. Adding a fixture that was not there before needs consent, and repositioning your connection into a network utility operator's drain needs consent, full stop. So "adjacent wall, gully trap moves a bit" is cheap and exempt. "Sink out to the island" is a longer run, possibly a vent, and a conversation with council.
Buy boxes you can re-front
In a well-made kitchen the door is not part of the cabinet. It is hung off it. Melteca, the Laminex NZ melamine panel most of Auckland's cabinetry is built from, is a decorative overlay pressed onto Superfine particleboard or Lakepine MDF, double-faced and pre-finished, supplied from 9 to 30mm. Your carcass is Melteca. Your doors are Melteca. Same board, different decor. Laminex's own data sheet puts Melteca at the Building Code's B2.3.1(c) durability threshold, the five-year one for elements easy to get at and replace, and adds a ten-year limited warranty on top.
What makes a box re-frontable is boring, in both senses. Cabinets built to the 32mm system index their hardware to a row of 5mm holes at 32mm centres, and concealed hinges sit in a 35mm cup. If your carcasses are standard modules on standard boring, a new set of fronts is a measured order and a screwdriver, which is the whole argument for re-fronting rather than replacing. If your joiner built one-off boxes with hinges wherever they landed, the fronts are bespoke twice. Ask for the fronts as a separate line: a supplier who can price them separately is building modular boxes.
| Element | If you plan ahead | If you don't | Deciding detail |
|---|---|---|---|
| Cabinet carcasses | Re-fronted, boxes stay | Skipped | Standard modules, 32mm boring |
| Doors and drawer fronts | Replaced (intended) | Replaced (forced) | Priced as a separate line |
| Benchtop | Replaced (planned) | Replaced (forced) | Templated to the boxes |
| Sink, waste, gully trap | Untouched | Re-drained | Sink on a wall in both plans |
| Rangehood and duct | Untouched | Re-ducted through a new roof | Duct exits a wall that stays |
| Island | Unbolted and moved | Demolished | Whether services run into it |
| Appliances | Move | Move | Nothing is fixed to the building |
The island is a trap, not a feature
Everyone wants the island. In a staged Point Chevalier kitchen it is the most expensive way to lock yourself in. An island with a sink or hob in it is a plumbed, wired, ducted, half-structural object: waste means going under the floor, and extraction means ducting through a ceiling and roof you are about to remove. Those are services on the wrong wall, except the wall is the floor. An island with nothing in it is furniture: unbolt it, slide it, re-top it. Yours will land somewhere else in a bigger room, so size it as a free-standing piece from the start. Push the extraction onto the survivor wall too: a ducted rangehood on an external wall that stays is a short run and a wall cap, where a ducted island hood is a hole in a roof with a five-year life on it.
The benchtop is the honest write-off
Not everything survives. The benchtop cannot: it is templated to the cabinets you have, because the fabricator measures the installed boxes rather than the drawing, so the moment the layout changes, so does the top. Take the write-off deliberately. Laminate on stage one and stone on stage two is not a compromise, it is the correct sequencing: laminate is materially cheaper, wears perfectly well over five years, and frees money for the boxes and hardware you keep. Laminex's own limitations rule Melteca out for sink bench tops anyway, which is rather the point: the top is a separate purchase with separate rules.
On engineered stone, be careful who you take advice from. It is legal in New Zealand: Australia banned it in July 2024 and New Zealand did not follow, MBIE consulted on options including licensing and a possible ban, and WorkSafe publishes guidance under the general duties of the Health and Safety at Work Act 2015. The risk is a fabrication and dust-control problem in the workshop, not a problem with the slab in your kitchen, and anyone telling you it is banned here has copied Australian content. The position could change, which is one more reason not to commit today.
Nine times out of ten the second kitchen isn't a kitchen job at all. It's a drainlayer, a sparky and a roofer undoing the first one. Get the services on the right wall and I'm just hanging doors.
Plan stage two and you re-front, not rebuild.
What goes wrong
The extension never happens. This is the big one. Rates move, a job changes, a baby arrives, and five years become nine and then never. Stage one cannot be a bad kitchen you are tolerating until the rescue arrives. It has to be one you would be content with for ten years: layout decisions made for the future, quality decisions made for the present.
The extension happens differently. The architect pushes the new rear wall two metres past your sketch, or puts an opening through the survivor wall you were counting on. Your sketch is a bet, so when the extension is designed, take the drawings back to your supplier before the builder starts. This is also why a site measure and a plan measure are not the same thing. Nobody site-measures a wall that has not been built.
Nobody wrote it down. In five years the joiner is a different joiner and the only person who remembers the plan is you. Get the as-built cabinet schedule, the decor codes, and the hardware brand and model in writing at handover. Assume the colour may be gone by then: five years is long enough for a Melteca decor to leave the range.
What to ask before you sign
- Which wall are the sink and waste on, and does that wall appear on my extension sketch?
- Have you looked at where the existing gully trap is, or are we picking a layout and finding out later?
- Are the carcasses standard modules on 32mm boring, or one-off boxes at odd widths?
- Can you price the doors and drawer fronts as a separate line?
- Is the island plumbed, and what would it take for it not to be?
- Where does the rangehood duct exit, and does that wall stay?
- Do I get an as-built cabinet schedule with decor codes?
Frequently asked questions
Do I need building consent to renovate a kitchen in Point Chevalier?
A like-for-like replacement in the same space, sink staying put, usually does not need building consent. Move the sink and you engage the Schedule 1 rules on sanitary plumbing and drains, which are exempt only within limits: the fixture count cannot increase, no specified system can be affected, and a drain alteration has to stay minor. Removing a load-bearing wall needs consent regardless. Confirm your job with Auckland Council and an LBP.
Can I really reuse kitchen cabinets after five years, or is that wishful thinking?
You can, provided the boxes were built for it. Standard-width modules bored on the 32mm system with 35mm hinge cups take a new set of fronts as a measured order. Melteca carcasses meet the Building Code's B2.3.1(c) durability requirement, the five-year one for elements easy to access and replace, and Laminex carries a ten-year limited warranty, so a five-year hold sits well inside its intended life. The wishful thinking is expecting one-off boxes to re-front cheaply: those fronts are bespoke twice.
Should I just put a cheap kitchen in now and a good one in after the extension?
No, and this is the most common way the staged plan fails. Cheap-now-good-later assumes the extension happens on schedule, and most slip or never happen, leaving you with a deliberately bad kitchen indefinitely. Staging is about putting services on a wall that survives and buying boxes you can re-front, not about downgrading the specification.
Will my Melteca colour still be available when I come to re-front?
Possibly not, and it is safer to assume it will not. Decor ranges change over five years, so a re-front that depends on matching a surviving panel is a risk worth designing out. Keep the Melteca you are retaining out of sight, as carcass interiors and shelving, or plan for the new fronts to contrast deliberately so a two-tone result reads as intentional.
Wouldn't it be cheaper to wait and do the extension and the kitchen together?
If you can genuinely afford it now then yes, one kitchen is cheaper than one and a bit. The honest answer depends on how real the five years are. Living with a failing kitchen for half a decade to save a re-front is a bad trade, particularly with kids in the house. If the extension is funded and eighteen months away, wait; if it is a five-year aspiration, renovate now.
Send us the plan you have and the one you want
MTN Kitchens has manufactured out of our own East Tamaki workshop for 23 years, across more than 2,000 kitchens, and we turn out ten-plus a week. We supply and install under one contract and one invoice, so nobody argues about whether a problem belongs to the cabinetmaker or the installer. No showroom, which is why the pricing is trade pricing. A kitchen installs over five to seven days, and we are Site Safe qualified, which is how head contractors like Spencer Henshaw put work through us.
Send us the scope, a few photos of what you have now, and your sketch of the extension, however rough. We can price off a rough scope and sharpen it once there are drawings, and we will have a trade-priced number back inside 24 hours, plus GST. More usefully, we will tell you which wall we would put the sink on and why, before you have spent anything. That conversation decides whether you buy one kitchen or two.
