Where can I find trustworthy information about how house insurers handle complaints?
In New Zealand, the most trustworthy places to find information about how house insurers handle complaints are the Insurance Council of New Zealand (ICNZ), the Financial Markets Authority (FMA), and the independent insurance dispute resolution schemes.
If you want to compare insurers, look for published complaints statistics and information about how complaints are investigated, rather than relying solely on customer reviews.
Best sources to start with
- Insurance Council of New Zealand (ICNZ)
Best for comparing insurers
Read the complaints data and Fair Insurance Code guidance
ICNZ publishes complaints data by insurer, including house and contents insurance complaints referred to independent dispute resolution schemes.
Its published 2024 data includes the number of complaints closed, how many were decided in the customer's favour, and how many favoured the insurer or resulted in a partial or agreed outcome. It also provides guidance on the complaint process. How to Make an Insurance Complaint (NZ)
Important: These figures cover complaints reaching external dispute resolution, not every complaint made directly to an insurer.
- Financial Markets Authority (FMA)
Read the FMA's insurance guidance
The FMA is New Zealand's financial markets regulator. Its guidance explains insurers' obligations to treat customers fairly, the role of fair conduct programmes, and how to escalate complaints.
This is a strong source for understanding the standards insurers are expected to meet, rather than simply reading customer experiences. InsuranceDisputes and consumer protection
- Insurance & Financial Services Ombudsman (IFSO) Scheme
IFSO independently handles eligible complaints about insurers and other financial service providers that belong to its scheme. Its decisions and case studies can help you understand how disputes are assessed in practice.
This is particularly useful if you want to learn how disputes about claim decisions, repairs, exclusions or settlement amounts may be resolved. Check that your insurer belongs to this scheme. Insurance & Financial Services Ombudsman SchemeResolving disputes and claims
- Consumer Protection — New Zealand Government
Read the guide to making a complaint about a financial service provider
This explains the complaint process, where to find your insurer's dispute resolution scheme, and what options are available if your insurer does not resolve the issue. Making a complaint about your financial service provider
How to compare house insurers fairly
If you're researching insurers before buying a policy, or assessing how well an insurer handles complaints, I recommend comparing these five things:
- Complaints relative to claims: A large insurer may receive more complaints simply because it handles many more claims.
- Outcomes: Look at the number of complaints upheld for customers, not just the total number of complaints.
- Internal resolution: Find out how quickly the insurer acknowledges complaints, investigates them and communicates decisions.
- Independent dispute resolution: Check whether customers can escalate unresolved disputes to an independent scheme.
- The type of complaint: A dispute about a declined house claim may tell you more about claims handling than a complaint about customer service.
ICNZ itself cautions that complaint totals need to be considered alongside each insurer's claims volume. Also, externally investigated complaints represent only a subset of all complaints. How to Make an Insurance Complaint (NZ)
My recommendation: Start with ICNZ's complaints data, then use the FMA's guidance to understand the standards insurers should meet. Together, these provide a useful starting point based on published evidence rather than anecdotal reviews.
