Pre-purchase building inspectors in New Zealand: prices and how to choose
Building inspectors check a house before you buy it and write a report on its condition, from minor maintenance to serious defects like leaks, rot or structural damage. The standard pre-purchase inspection in New Zealand follows NZS 4306, the residential property inspection standard. It is a visual inspection, so it cannot see behind finished walls, floors or ceilings.

How to choose a building inspector
- Confirm the inspection and report will follow NZS 4306, and ask for a sample report.
- Ask to see proof of professional indemnity insurance and what it covers.
- Ask about their qualifications, and whether they belong to the Building Officials Institute of New Zealand or the NZ Institute of Building Inspectors.
- Ask whether moisture readings, the roof space and the subfloor are included in the price.
- Book your own inspection rather than relying on a report the seller paid for.
- For each problem found, ask how urgent it is, then get a builder to price the repairs.
Red flags
- A report with no photos, or problems listed with no explanation.
- No professional indemnity insurance, or unwillingness to show it.
- Links to the selling agent, or relying on a vendor-supplied report.
- Very cheap reports that skip the roof space, subfloor or moisture readings.
Frequently asked questions
How much does a building inspection cost in NZ?
Usually about $450 to $600 plus GST for a standard house, rising with the number of bedrooms. One Christchurch inspector charges $475 plus GST for a one-bedroom home and $599 plus GST for six or more bedrooms. Larger or more complex homes in the main cities can cost $800 or more.
What does a pre-purchase inspection check?
The roof, exterior cladding, interior, subfloor and roof space, with moisture readings, looking for issues like leaks, rot, borer, damp, structural damage and faulty plumbing or wiring. It does not check whether past work had a building consent. Check the council records or a LIM for that.
Can I use the report the seller provides?
Get your own. The seller is the inspector's client, so you are unlikely to have any comeback if their report misses something.
What warning signs should I look for?
Plaster-style monolithic cladding from the 1980s to mid-2000s, black plastic plumbing from the late 1970s and early 1980s, and asbestos materials in homes built from the mid-1940s to the mid-1980s.
Can I add a healthy homes report?
Many inspectors offer one as an add-on. Two Christchurch inspectors charge $175 plus GST for a healthy homes compliance report alongside a building report.
