Questions
How accurate is the estimate?
It is a planning range built from NZ unit rates (per metre, per m², per room) for a typical residential job, replaced by real Connect quote rates as they come in. Site access, ground, materials and season move the real price, so post the job for actual quotes.
Does the price include GST and materials?
Yes. Every figure is incl. GST and covers supply and labour for what the "Includes" line says. Anything in "Not included" is priced separately.
Is this a quote?
No. It is an estimate to help you budget and describe the job. Post it on Connect, free, and vetted local tradies will quote the actual job.
Why a range, not one number?
Two tradies rarely price the same job the same way. Low, typical and high show where most jobs land, so a quote in that range is normal and one well outside it is worth asking about.
