Concreting Prices New Zealand

Concreting in New Zealand ranges from NZ$35 per m² for basic services like plain slabs to NZ$750 for major projects like retaining walls. Prices include GST. Site preparation and access conditions affect final pricing.

The most common finishes are plain (broom-finished) concrete, exposed aggregate with decorative stones, coloured concrete using oxide pigments, and stamped or stencilled concrete that mimics stone, slate, or tile patterns. Each finish has different cost, durability, and aesthetic characteristics.

Well-laid concrete typically lasts 25–50 years or more. Longevity depends on the quality of the mix, proper sub-base preparation, adequate curing, and regular sealing (every 2–5 years for decorative finishes). Driveways and high-traffic areas may need resealing more frequently.

Most standard residential concreting (slabs, driveways, paths) does not require a permit. However, you may need approval for: driveways that cross public land, retaining walls above a certain height (varies by region), work affecting drainage, and any structural concrete like house slabs. Always check with your local council or authority before starting work.
