What it costs
What it costs to build a house in New Zealand
In Q1 2026 the average consented new dwelling worked out at $3,229 per square metre, excluding land. A 200m² house at that rate is about $645,800 of building work — which is not the same thing as what you will actually pay.
Cost per square metre, by region
All six figures are the same period, so they compare like with like. They are the value owners put on the building work when they applied for consent, divided by the floor area — so they exclude land, and they are an average across everything from a small townhouse to an architectural one-off.

Why your quote will be higher
The per-square-metre figure covers the building. It does not cover most of what turns a section into a house you can live in. These are the lines that catch people out, and none of them are in the number above.
- Land. The single biggest cost in most of the country, and entirely absent from the figure above.
- Site works. Earthworks, retaining, drainage, driveway. Wildly variable — a flat section and a sloping one are different projects.
- Council development contributions. Charged per new dwelling by the territorial authority. Thousands, and it varies by council.
- Consent and inspection fees. Building consent, resource consent if you need one, and inspections through the build.
- Service connections. Power, water, wastewater, fibre. Rural sites can be an order of magnitude more.
- Landscaping, fencing, driveway finish. Usually excluded from a build contract and usually needed before you can move in.
- Contingency. Nobody plans for it and almost everybody uses it.
