10 Things to Check Before Hiring a Building Surveyor in New Zealand

A property can look reassuring at an open home and still leave important questions unanswered. Before you book a surveyor, decide what you need to understand: the condition before buying, workmanship before handover, a recurring leak, or a more complex building problem.

This guide is for homeowners and buyers choosing a building surveyor or property inspector. Boundary and subdivision work is a different discipline: LINZ explains that cadastral surveys require a licensed cadastral surveyor or someone working under their direction.

1. Check the individual’s qualifications and current membership

Ask who will actually inspect the property, then check that person’s qualifications and membership. A company logo alone does not tell you who is doing the work. Settled.govt.nz notes that New Zealand has no licensing regime for property inspectors, making those checks particularly useful.

Use the NZIBS registered-surveyor directory and, where relevant, RICS Find a Member. Membership is a useful credential to verify alongside relevant experience and scope; it is not a guarantee that every defect will be found.

At Castlebridge Surveys, Nick Roberts is a Chartered Building Surveyor, FRICS — Fellow of the Royal Institution of Chartered Surveyors — and a registered NZIBS member. His Castlebridge listing appears in the NZIBS directory. Read more about Nick’s qualifications and background. RICS explains the FRICS designation and fellowship on its own website.

Ask: “Who will inspect my property, and where can I verify their professional membership?”

2. Look for experience with your type of property

Choose experience that matches the building and the question. An older villa, a recently completed townhouse and an apartment in a larger complex deserve different conversations before the scope is agreed.

NZIBS’s guidance for home buyers recommends relevant training and experience in pre-purchase inspections, including understanding weathertightness risks, deterioration and visible defects. Ask the surveyor to explain their approach to a property like yours without requesting confidential client information.

Nick has more than 20 years of construction experience across the UK and New Zealand. Castlebridge’s work includes existing homes, new construction inspections, and commercial-building and multi-unit apartment due diligence.

Ask: “What relevant experience do you have with this building’s age, construction and the concerns I’ve raised?”

3. Confirm whose interests the surveyor represents

Commission advice for your own decision, and ask about any connection with the seller, agent, builder or proposed repair contractor. A recommendation can be helpful, but it should not replace your own checks.

HOBANZ recommends an inspector independent of the seller and real estate agent. Separately, Settled.govt.nz cautions against relying on a report commissioned by someone else: the inspector’s contract may be with that person, rather than you.

If an existing report is available, ask the author whether you can rely on it and on what terms. Do not assume that receiving a PDF makes you the client.

Castlebridge provides independent building inspections. When you enquire, explain who is involved and how you intend to use the advice.

Ask: “Will I be the named client, and are there any relationships or interests I should know about?”

4. Request evidence of appropriate insurance

Ask for current evidence of professional indemnity insurance and an explanation of the cover relevant to the proposed work. Public liability cover is also worth discussing. A headline insurance figure is only the start of the conversation.

Settled.govt.nz recommends choosing an inspector with professional indemnity insurance. HOBANZ also advises checking the adequacy and exclusions of professional indemnity and public liability policies.

Ask how the policy relates to your engagement, and read the liability terms in the proposal. Insurance does not mean every defect, loss or claim is covered. For a substantial purchase or unusual risk, take advice on anything in the terms you do not understand.

Ask: “Can you provide current insurance evidence and explain any relevant exclusions or liability limits?”

5. Agree the inspection scope and reporting standard in writing

Make sure the proposal describes what is included, what is excluded and what you will receive. “Building report” is not a sufficiently detailed scope on its own.

Settled.govt.nz recommends a comprehensive residential inspection report meeting NZS 4306:2005. Ask your proposed inspector which standard applies and how it is reflected in the engagement. A specialist defect investigation or commercial assessment needs its own appropriate scope.

For a home inspection, clarify whether the work includes accessible roof and subfloor spaces, outbuildings, decks, visible drainage and moisture assessment. Ask separately about document review, specialist testing or anything else you expect.

Castlebridge’s pre-purchase inspection service explains the visible areas Nick assesses. Agree the final scope for your actual property before booking.

Ask: “Which standard and scope are you proposing, and what work would require a separate engagement?”

6. Check how access restrictions and hidden defects are handled

Look for a surveyor who explains the limits clearly. A visual inspection cannot see through finished walls or guarantee the condition of concealed materials.

BRANZ’s pre-purchase inspection guidance describes the importance of agreeing scope and limitations, recording inaccessible areas, and identifying when further investigation is needed. It also explains that a report using only non-invasive equipment cannot guarantee weathertightness.

Before the visit, discuss keys, roof-space hatches, subfloor access and any known restrictions with the inspector and the person arranging entry. Ask how an uninspected area will be identified in the report and whether a return visit would be necessary.

Ask: “If an important area cannot be accessed, how will you report that and advise me on the next step?”

7. Ask specifically about weathertightness and moisture

Raise leak concerns when you book, rather than assuming every inspection includes a detailed investigation. Tell the surveyor about staining, recurring dampness, previous repairs or known cladding concerns.

MBIE advises engaging an experienced expert with weathertightness expertise when a property shows potential signs of leaking. It also highlights the importance of considering the wider complex when assessing an apartment or townhouse for weathertightness.

Ask what the proposed moisture assessment can establish and what would trigger further work. Castlebridge’s weathertightness risk and moisture testing service explains the difference between surface readings and invasive testing. Invasive work needs a separately agreed scope and the owner’s permission.

Ask: “Is the proposed assessment sufficient for these concerns, or should we agree a specialist investigation?”

8. Review a sample report and the follow-up process

Ask for an anonymised sample before deciding. Read it as if it concerned your own home: can you understand the findings, their significance and what you should do next?

NZIBS’s home-buyer guidance describes clearly explained reporting, visible defects, significant maintenance and guidance on further investigation. A long document is not automatically a useful one. Look for a report that helps you separate an observation from an unanswered question.

Check whether you can discuss the findings with the person who inspected. Castlebridge’s pre-purchase service includes a personal discussion of the report’s priorities. If you want repair-cost advice, ask whether that is included and what its limitations would be.

Ask: “Can I see a sample report, and will the inspecting surveyor explain the findings to me?”

9. Confirm the fee, availability and reporting deadline

Compare written proposals for the same work. Ask for the total fee, whether GST is included, any travel charges and what would cause an additional charge. Then confirm both the inspection date and the report delivery date.

Give the surveyor your actual decision deadline at the first enquiry. Allow time to read the report, ask questions and arrange any further assessment. Discuss the wording and timing of purchase conditions with your lawyer or conveyancer; a surveyor’s booking does not change your contract deadline.

Castlebridge primarily serves Auckland and Waikato, including Hamilton. Other locations are considered by arrangement and subject to availability, with any travel fees discussed upfront. Send Nick the address and your deadline to check the proposed scope, fee and availability.

Ask: “What is the total agreed fee, and when will I have the written report and an opportunity to discuss it?”

10. Choose someone who knows when another specialist is needed

A useful surveyor will identify questions outside the agreed scope or their expertise. Ask how they distinguish a visible concern from a diagnosis that needs additional evidence.

For a purchase, keep legal advice alongside the building assessment. Settled.govt.nz recommends assembling a professional support team and notes that an engineer may also be needed, depending on the property.

For an existing home with a persistent defect, explain what you need the advice for: planning repairs, understanding remediation proposals or supporting a dispute. Castlebridge’s building surveying consultancy covers these more focused enquiries and explains when further investigation or another specialist may be appropriate.

Ask: “If the findings raise a structural, legal or specialist concern, how will you identify the next advice I need?”

A simple checklist before you book

Keep these details together when comparing proposals:

Discuss your property with Castlebridge Surveys

Start with the property address, listing link if available, known concerns and your decision deadline. For an existing home purchase, explore pre-purchase inspections. For handover, see new construction inspections. For leaks or a more complex problem, discuss moisture testing or surveying consultancy.

Contact Nick Roberts to discuss the scope that fits your property. The aim is a clear understanding of what will be assessed, what the advice will establish and what remains to be investigated.
