How much does a 40 m² concrete driveway cost in NZ?
Roughly $3,600–$6,400 for a plain broom finish, or $6,000–$11,200 for exposed aggregate or stamped concrete, GST included. Those figures cover supply and lay on a flat, accessible site. Site costs such as spoil removal, extra hardfill and the vehicle crossing are quoted on top.
How much is concrete per square metre in NZ?
For a finished driveway in Auckland, expect $90–$160/m² for a plain broom finish, $150–$250/m² for exposed aggregate and $150–$280/m² for stamped or patterned concrete, all GST inclusive. Raw ready-mix supply is a different figure again, at around $160–$250 per cubic metre plus GST.
Are concrete driveway prices plus GST or including GST?
Both are used, which is why quotes are so hard to compare. Trade quotes are usually written plus GST and consumer guides usually quote inclusive. Multiply a plus-GST figure by 1.15 to compare it against an inclusive one. Every price in this article includes GST.
Is exposed aggregate more expensive than plain concrete?
Yes. Exposed aggregate runs about $150–$250/m² against $90–$160/m² for a plain broom finish, GST included. The extra pays for the decorative stone, the wash-off or polish, the additional labour on the day, and sealing. Stone choice moves the number more than the size of the driveway does.
How thick should a concrete driveway be in NZ?
The NZ Master Concrete Placers Association code sets a 100 mm minimum for a domestic driveway on a compacted 100 mm base, in 20 MPa or stronger concrete. If a truck, horse float or heavy campervan will use it, you want a designed slab of 125–150 mm, and that thickness should be itemised in your quote.
Do I need approval for a concrete driveway in Auckland?
For the vehicle crossing between the kerb and your boundary, yes. Auckland Transport approves it and written approval is required before work starts. Auckland Council administers the Auckland Unitary Plan, whose Chapter E27 covers vehicle access, and Council handles any resource or building consent. They are two separate processes.
How much should I allow on top of the quoted rate?
Add about 10% as contingency for ground conditions nobody can see until excavation starts. On top of that, budget separately for spoil removal, any extra hardfill, drainage, and the vehicle crossing if you are altering one, since none of those sit inside a per-square-metre rate.
