When hiring a building inspector in New Zealand, checking their insurance is just as important as checking their qualifications. A reputable inspector should carry at least professional indemnity insurance and public liability insurance — without these, you could be left out of pocket if something goes wrong with their report or during the inspection itself.
Why Insurance Matters for Building Inspections
A pre-purchase building inspection report is often the basis for major financial decisions — sometimes involving hundreds of thousands of dollars. If an inspector misses a significant defect, such as hidden weathertightness issues or structural problems, and you suffer a financial loss as a result, you need to know there is a way to recover that loss. Insurance is the mechanism that makes that possible.
Without adequate insurance, even a well-intentioned inspector may be unable to compensate you if their report turns out to be negligent or inaccurate.
The Two Key Types of Insurance
Professional Indemnity Insurance (PI)
Professional indemnity insurance (sometimes called errors and omissions insurance) covers claims arising from professional mistakes, negligence, or failure to provide the standard of service expected. For a building inspector, this means:
- Missing a significant defect that was reasonably discoverable during a visual inspection
- Providing incorrect or misleading advice in the written report
- Failing to flag a potential compliance issue
PI insurance is the most critical cover for a building inspector. Always ask for confirmation that it is current and find out the level of cover — a minimum of $1 million per claim is generally considered reasonable, though higher cover may be appropriate for high-value properties.
Public Liability Insurance
Public liability insurance covers third-party property damage or personal injury that occurs during the course of the inspector's work. For example, if the inspector accidentally damages a roof tile while accessing the roof, or a ladder falls and damages a fence, public liability cover protects both you and the inspector.
A minimum of $1 million in public liability cover is a common benchmark, though many reputable inspectors carry $2 million or more.
Other Insurance Worth Asking About
While PI and public liability are the essentials, some inspectors may also carry:
- Business interruption insurance — less relevant to you as a client, but signals a professional operation
- Tools and equipment insurance — covers their inspection equipment
- Statutory liability insurance — covers unintentional breaches of NZ statutes
These are not mandatory for you to require, but their presence can indicate a well-run business.
What to Ask Before Hiring an Inspector
Before engaging a building inspector, ask these questions directly:
| Question | Why It Matters |
|---|---|
| Do you hold current professional indemnity insurance? | Protects you if the report is negligent |
| What is your level of PI cover per claim? | Ensures cover is adequate for your property value |
| Do you hold public liability insurance? | Covers accidental damage during the inspection |
| Can you provide a certificate of currency? | Verifies the policy is active, not lapsed |
| Are there any exclusions relevant to this inspection? | Some policies exclude certain property types or defects |
A reputable inspector will have no hesitation providing a certificate of currency — a document from their insurer confirming the policy is active. Be cautious of anyone who is vague or reluctant about this.
Qualifications and Licensing in NZ
It is worth noting that building inspection is not a strictly licensed trade in New Zealand in the same way that electrical or plumbing work is. However, many inspectors hold qualifications such as being a Licensed Building Practitioner (LBP), a registered architect, or a member of a professional body such as the New Zealand Institute of Building Surveyors (NZIBS). Membership of such bodies often requires members to maintain professional indemnity insurance as a condition of membership — so checking credentials and insurance go hand in hand.
For context on building standards and compliance in NZ, MBIE Building Performance is the key government authority, and BRANZ provides technical research and guidance that underpins good inspection practice.
Red Flags to Watch Out For
- Inspector cannot or will not confirm their insurance details
- Very low-cost inspection with no mention of insurance
- No written contract or terms of engagement
- Report disclaimer that attempts to limit all liability entirely (some limitation is normal, but blanket exclusions are a concern)
- No professional memberships or verifiable qualifications
When to Call a Professional
If you are buying a property — particularly an older home, a leaky building era property (roughly 1990s–2000s construction), or a complex dwelling — always engage a qualified, insured building inspector before signing a sale and purchase agreement. This is not a step to skip or cut costs on. A thorough inspection by an insured professional can save you from a very costly mistake.
