Yes, a building inspector can generally access a property without the vendor being physically present — but this needs to be arranged properly beforehand. In New Zealand, pre-purchase building inspections are a standard part of the property buying process, and the logistics of access are usually sorted out between the real estate agent, the vendor, and the buyer.
How Access Is Typically Arranged
In practice, the vendor's real estate agent is the key person who organises access to the property. When a buyer commissions a building inspection, the agent will usually arrange a time that suits all parties and either attend themselves or provide the inspector with a key or access code. The vendor does not need to be on-site for this to happen — they simply need to have given their consent through the agent.
This is a very common arrangement in NZ. Vendors are often happy to allow access without being present, as it keeps the sale process moving smoothly.
Does the Vendor Have to Agree?
Yes — the vendor must give permission for any inspection to take place. A building inspector (or anyone else) cannot enter a private property without the owner's consent. This is a basic legal principle in New Zealand. If the vendor refuses access, the buyer may need to negotiate this as part of the sale conditions, or reconsider whether to proceed.
Most standard sale and purchase agreements in NZ include a building inspection condition, which effectively means the vendor has agreed to allow reasonable access for an inspection as part of accepting the offer. If you're unsure about your specific agreement, check with your solicitor.
What About Tenanted Properties?
If the property is tenanted, the situation is a little more complex. Under the Residential Tenancies Act, tenants have the right to quiet enjoyment of their home. The landlord (vendor) must give the tenant proper notice before allowing anyone to enter — typically at least 48 hours' written notice for an inspection. The tenant does not have to vacate, but they also cannot unreasonably refuse entry once proper notice has been given.

What the Inspector Can and Cannot Do
A pre-purchase building inspector will carry out a visual inspection of the property — they are not authorised to open walls, lift fixed flooring, or carry out invasive testing unless specifically agreed. Their job is to assess what is reasonably visible and accessible on the day.
If the vendor or agent has restricted access to certain areas (for example, a locked garage or a room that isn't accessible), the inspector should note this in their report. A good inspector will clearly document any areas they were unable to assess.
Choosing a Qualified Inspector
In New Zealand, building inspectors are not currently required by law to hold a specific licence, though this is an area that has been under discussion. However, many reputable inspectors are Licensed Building Practitioners (LBPs) or members of professional bodies such as the New Zealand Institute of Building Inspectors (NZIBI) or similar recognised organisations. Choosing someone with recognised qualifications gives you greater confidence in the quality of their report.
You can check LBP status at Licensed Building Practitioners. For guidance on what a good building report should cover, BRANZ and MBIE Building Performance are useful references.
What Should Be in the Inspection Agreement?
Before the inspection goes ahead, make sure you have a written agreement with your inspector that covers:
- Scope of the inspection — what areas and systems will be assessed
- Access arrangements — who will provide access and when
- Limitations — any areas that may not be accessible
- Report format and timeframe — when you'll receive the written report
- Insurance — confirm the inspector holds professional indemnity insurance
Tips for Buyers
- Arrange the inspection as soon as your offer is accepted, to stay within your due diligence timeframe.
- Try to attend the inspection yourself if possible — being on-site lets you ask questions and get a feel for any issues firsthand.
- If the agent is providing access, confirm the time and arrangements in writing.
- Ask your inspector whether they've had full access to all areas, and check their report for any noted limitations.
When to Call a Professional
If you have concerns about the structural integrity, weathertightness, or compliance of a property, a qualified building inspector is your first port of call. For issues that may involve specific systems — such as plumbing, electrical, or gas — you may also want specialists to assess those areas separately. Restricted work in those trades must be carried out by licensed professionals registered with the Electrical Workers Registration Board or the Plumbers Gasfitters & Drainlayers Board.
