Local rules for foundation work

Foundation work in New Zealand falls under the building rules. The building regulator lists a Foundations licence for Licensed Building Practitioners (LBPs), and an LBP with a foundation licence can do restricted building work in the construction and alteration of foundations. Before you sign, ask the builder whether they hold the Foundations licence, and ask for the licence number.

Season and curing

November is spring. Summer from December to February gives dry days for digging and pouring, while winter from June to August brings rain, cold and wet ground, which slows the curing of concrete. Book pours for the warmer months where you can, and confirm the weather window in the request.

Units, quotes and extra costs

Slab prices are per square metre and underpinning is per job. Give the area in square metres and the thickness of the slab in millimetres. Some quotes add GST on top, so ask for the total. Site preparation and soil conditions also change the price, and the search results name them as the main factors alongside slab thickness.

What to put in your request

Name the work needed, the dimensions or volume, the soil and the plot, and whether concrete reinforcement is needed. Add the site address, the deadline and your budget. A photo of the site and the access route helps sellers judge how much machinery the job needs.

Describe the work once in the BlaBlaPrice chat. The AI reads the request, asks for missing details and looks through sellers' websites in New Zealand, then shows the prices and businesses it found. Sellers registered on BlaBlaPrice reply in the chat with their own offer, and your contact details stay hidden until you choose to share them.

Questions and answers

How much does a concrete slab cost in New Zealand?

Sellers' websites list slab foundations at about NZ$100 to NZ$200 per square metre, and budget estimates from NZ$50 to NZ$70 per square metre. Prices depend on site preparation and slab thickness.

Does a foundation builder need a licence?

Foundation work is covered by the Foundations licence for Licensed Building Practitioners, so ask whether the builder holds it before you hire them.

Is GST included in concrete prices?

Some quotes add GST on top, for example a shed concrete floor at about NZ$110 per square metre plus GST. Ask for the total.

Is winter a bad time for a pour?

Winter, from June to August, is cold and wet, which slows curing. Spring or summer suits a pour better.
