A kitchen renovation is one of the bigger financial decisions you’ll make as a homeowner. Done well, it adds real value to your property and makes daily life genuinely better. Done poorly – or without a clear understanding of costs upfront – it can blow out fast.
This guide covers what kitchen renovations actually cost in New Zealand right now, what drives those costs up or down, and how to make sure your budget is realistic before work starts. Whether you’re in Ashburton, Mid Canterbury, or across Central Otago, the same principles apply.
The honest answer is: it depends on what you’re actually doing. “Kitchen renovation” covers everything from a flat pack install with new benchtops right through to a fully custom kitchen with engineered stone, new plumbing configuration, and premium appliances.
Here’s a realistic breakdown of what you’re likely to spend at each level:
| Kitchen type | Typical cost range | What’s typically included |
| Flat pack install (labour only) | $1,500 – $4,500 | You supply the kitchen, installer fits it. Standard size, no demo. |
| Flat pack – supply & install | $8,000 – $18,000 | Flat pack kitchen supplied and installed. Cost varies by brand and size. |
| Mid-range complete replacement | $18,000 – $35,000 | Remove old kitchen, supply and install new cabinetry, benchtop, and hardware. |
| Premium / semi-custom | $35,000 – $60,000+ | Higher-spec materials, custom layouts, stone benchtops, premium appliances. |
These figures are for the kitchen itself – cabinetry, benchtops, hardware, and installation labour. They don’t include electrical or plumbing work, consent (if required), or appliances unless stated. Those costs add to the total.
The most common job for homeowners in Ashburton and Mid Canterbury falls in the flat pack supply-and-install or mid-range complete replacement range – roughly $10,000 to $35,000 depending on the size and specification.

The single biggest variable is whether you’re keeping the existing kitchen layout or changing it. Moving plumbing or shifting where the sink, dishwasher, or appliances sit involves a licensed plumber, and potentially an electrician – that adds cost.
Other factors that affect price:
If your layout stays the same and you’re replacing like-for-like, costs are easier to contain. If you’re reconfiguring the space, budget more room for trades and coordination.

For most homeowners, yes – provided the spend is proportionate to the property value. As a general rule of thumb, kitchen renovation spend of around 5–10% of your home’s value tends to deliver the best return, particularly if you’re planning to sell within a few years.
A well-executed kitchen renovation in Ashburton or Mid Canterbury can make a meaningful difference to a property’s appeal and sale price, particularly in the current market where buyers are scrutinising condition carefully. Quality kitchens stand out – and a dated, poorly functioning kitchen can be a genuine deterrent.
If you’re renovating to live in rather than sell, the calculus is different. Comfort, functionality, and how the kitchen fits your daily routine matter more than resale optimisation.
You can, but it comes with real risk if you don’t have the trade experience. Flat pack kitchens look straightforward – the instructions are designed for DIY – but getting cabinetry level, plumb, and properly secured in a real house (with real floor variations, wall angles, and structural considerations) is harder than it looks.
Common DIY mistakes include cabinets that aren’t properly fixed to studs, doors and drawers that don’t align correctly, benchtop joins that aren’t watertight, and kickboards that don’t sit flush. These aren’t just aesthetic problems – some create safety or durability issues over time.
If you’re not trade-qualified, the cost of fixing a poor DIY installation often ends up higher than hiring a professional in the first place. A qualified kitchen installer brings the tools, the technique, and the experience to get it right first time.
Installation-only pricing (where you supply the kitchen and the installer fits it) typically runs from $1,500 to $4,500 for a standard flat pack kitchen in NZ. This assumes a straightforward layout with no demo, and a kitchen that’s been measured and ordered correctly.
More complex jobs – those involving demolition of an existing kitchen, non-standard layouts, coordination with plumbing and electrical trades, or larger kitchen sizes – will sit higher. A full project management approach, where the installer coordinates all trades, is worth the premium for most homeowners who don’t want to manage the process themselves.
At Fitted Joinery Installation, pricing is clear and agreed upfront. No inflated quotes, no surprise variations – just transparent pricing for quality installation across Ashburton, Mid Canterbury, and Central Otago.
In most cases, a standard kitchen renovation – replacing cabinetry and benchtops in the same position – does not require a building consent. You’re not changing the structure of the building.
However, consent may be required if you’re moving load-bearing walls, changing the configuration of plumbing beyond what’s considered minor work, or making other changes that affect the building’s structure or weathertightness. Your local council (for Ashburton, that’s Ashburton District Council) is the definitive authority on what requires consent in your specific situation.
A qualified installer can advise on what’s likely to be straightforward versus what might trigger a consent requirement before any work begins.
A flat pack kitchen installation – where the kitchen has already been ordered and delivered – typically takes two to four days on site for a standard-sized kitchen. That assumes the space is prepped, the plumber and electrician have done their rough-in work, and there are no significant complications.
A full kitchen replacement, including demolition, prep, installation, and final trades sign-off, more commonly runs one to two weeks depending on the scope and how trades are sequenced. Kitchens that involve consent, structural work, or significant reconfiguration can take longer.
Good project management makes a significant difference to how smoothly this goes. Getting trades sequenced correctly – plumber, installer, electrician, in the right order – avoids delays and keeps costs on track.
