In New Zealand, most professional building inspectors aim to deliver your written report within 24 to 48 hours of completing the on-site inspection. Some inspectors will turn it around the same day, while more complex properties — or inspectors with a heavy workload — may take up to three or four working days. It's always worth confirming the expected turnaround time before you book.
Why the Timing Matters
For homebuyers, timing is everything. Building inspection reports are commonly ordered during the due diligence period of a property purchase, and many sale and purchase agreements in NZ allow only a short window — often five to ten working days — for the buyer to review reports and raise concerns. Receiving your report promptly gives you time to:
- Read and understand the findings carefully
- Get quotes from tradespeople for any remedial work
- Negotiate with the vendor if significant issues are found
- Make an informed decision about whether to proceed
If your report arrives late and your due diligence period is tight, you may feel pressured to make decisions without enough information. That's a situation worth avoiding.
What's a Reasonable Turnaround?
As a general guide:
| Inspection Type | Typical Report Turnaround |
|---|---|
| Standard pre-purchase inspection | 24–48 hours |
| Large or complex property | 2–4 working days |
| New build Code Compliance inspection | Same day to 48 hours |
| Weathertight / moisture investigation | 2–5 working days |
These are approximate timeframes only — always confirm with your specific inspector at the time of booking.
What Should the Report Include?
A thorough written building inspection report should cover:
- Structural elements — foundations, framing, roof structure
- Exterior cladding and weathertightness — a key concern in NZ given our leaky building history
- Roof condition — materials, flashings, gutters and downpipes
- Interior — walls, ceilings, floors, doors and windows
- Plumbing and drainage (visual inspection only — not a licensed plumber's assessment)
- Electrical (visual inspection only — not a licensed electrician's assessment)
- Moisture readings where relevant
- Photographs of defects or areas of concern
- A summary of findings, often categorised by urgency
Note that a building inspector's report is a visual, non-invasive assessment. It does not replace specialist reports from licensed plumbers, electricians, or structural engineers where those are warranted.
Verbal Briefing on the Day
Many inspectors will give you a verbal summary at the end of the inspection while you're still on site. This is a great opportunity to ask questions and get a feel for the key issues. However, the written report is the official document — verbal comments alone are not sufficient for making major financial decisions or for any legal purposes.
What If Your Report Is Taking Too Long?
If you haven't received your report within the timeframe your inspector quoted, it's perfectly reasonable to follow up with a polite phone call or email. Delays can happen, but given the time-sensitive nature of property transactions, a good inspector will communicate proactively if they're running behind.
If you're consistently struggling to get a response, that may be a sign to reconsider using that inspector in future.
Choosing a Qualified Inspector
In New Zealand, building inspection is not a licensed trade in the same way that electrical or plumbing work is — there is currently no mandatory licensing regime for pre-purchase building inspectors. However, reputable inspectors will typically:
- Hold a qualification in building, construction, or a related trade
- Be a member of a professional body such as the New Zealand Institute of Building Surveyors (NZIBS) or similar
- Hold professional indemnity and public liability insurance
- Work to a recognised standard or methodology
Always ask about qualifications, insurance, and experience before booking. You can find qualified local building inspectors on tradedirectory.co.nz.

When to Call a Professional
If your building inspection report flags concerns around:
- Electrical systems — have a registered electrician (check EWRB) carry out a proper assessment
- Plumbing or drainage — engage a licensed plumber or drainlayer (check PGDB)
- Structural issues — consult a structural engineer
- Weathertightness or leaky building concerns — consider a specialist weathertight investigation
These are areas where a building inspector's visual report is a starting point, not a final word. Licensed tradespeople and engineers can provide the detailed assessments needed for remediation decisions.
For any building work that follows, check whether a building consent is required through your local council. MBIE Building Performance has guidance on Schedule 1 exemptions, but always confirm with your council before starting work.
