Every question, every answer, every source

If your home insurance claim has been declined in New Zealand, the strongest challenge is usually built around the insurer’s stated reason for declining, evidence of what caused the damage, and the exact wording of your policy.

Before lodging a complaint or asking the insurer to reconsider, gather evidence that addresses the reason for the decline directly. You do not necessarily need to prove everything yourself, but you should build a clear, documented case.

1. The evidence to gather first

Evidence checklist

0 of 8

The insurer’s written decisionThe decline letter, the specific policy clauses relied on, the reasons for declining, and any reports or evidence the insurer says support its decision.

Your complete insurance policyThe policy wording that applied on the date of the damage, including exclusions, definitions, excesses, endorsements and any special conditions.

Photos and videos of the damageOriginal files showing the damage, affected rooms or structures, surrounding areas and any visible signs of the cause. Keep dates and metadata where possible.

An independent expert reportWhere relevant, a report from a suitably qualified builder, engineer, roofer, plumber or other specialist explaining the likely cause, when it occurred, and whether it is consistent with an insured event.

A timeline of eventsWhen the damage was first noticed, what happened before and after, when you notified the insurer, inspections, repairs, and all communications.

Repair and mitigation recordsQuotes, invoices, receipts, emergency repair records, drying or remediation reports, and evidence of steps taken to prevent further damage.

Evidence of the property’s condition before the eventPrevious inspection reports, maintenance records, dated photographs, purchase or building reports, and records of earlier leaks or repairs.

2. Match the evidence to the reason for declining

The most useful evidence depends on what the insurer says happened.

Reason for decline	Evidence that may help
Gradual damage or wear and tear	Independent building report distinguishing long-term deterioration from a specific event, plus dated photos and maintenance records.
Storm, flood or other weather damage	Weather records, photos taken immediately after the event, roof or drainage inspections, and an expert opinion on causation.
Leaking pipe or water damage	Plumber’s report, leak detection results, moisture readings, photographs and repair records.
Pre-existing damage	Pre-purchase inspection reports, earlier photos, maintenance records and evidence establishing when the damage first appeared.
Exclusion in the policy	The exact policy wording, evidence about the actual cause of damage, and an explanation of why the exclusion may not apply.
Incomplete or allegedly inaccurate information	Your original application, renewal documents, emails and other records showing what you disclosed and when.
Disagreement over repair costs	Itemised quotes, an independent scope of works, invoices and a breakdown of the disputed amounts.

New Zealand Consumer Protection specifically recommends thinking creatively about proof: where receipts are missing, photographs, bank statements and repair documents may help establish a loss. It also advises unhappy claimants to complain to their insurer and request another assessor review the decision. Insurance

3. Build a clear case for reconsideration

Create a short document with three columns:

• Insurer’s position: Quote the precise reason for the decline and the policy clause.
• Your evidence: Identify the photograph, expert report, email or other document that addresses that point.
• Why it matters: Explain how the evidence challenges the insurer’s factual conclusion or interpretation of the policy.

Keep the original files, back up your records and retain proof of when you sent each document. Avoid undertaking destructive repairs or discarding damaged materials before documenting them, where it is safe and practical to preserve them. Do not delay urgent repairs needed to protect the home.

4. Know where to escalate in New Zealand

1. Make a formal complaint to the insurer. State that you dispute the decline, explain why, attach supporting evidence and specify the outcome you want. Ask for a written response and a review by someone not responsible for the original decision, where possible.
2. Use the insurer’s independent dispute resolution scheme if needed. New Zealand financial service providers belong to an approved scheme. Depending on the insurer, this may be the Insurance & Financial Services Ombudsman (IFSO) Scheme or another scheme. These services can provide free, independent assistance.

3. If the claim relates to a natural disaster, contact the New Zealand Claims Resolution Service. It offers homeowners support with disputes, including access to mediation and technical or legal assistance in appropriate cases. Resolving disputes and claimsDisputes and consumer protection

Check any applicable complaint deadlines and policy time limits promptly, particularly if the damage occurred some time ago.

Let’s narrow this down to your claim

The single most useful detail is why the insurer declined your claim. That will determine which evidence is likely to make the biggest difference.

What reason did the insurer give? For example, gradual damage, pre-existing damage, storm damage, a policy exclusion, or something else? If you share the wording from the decline letter (with personal details removed), I can help identify the strongest evidence to gather and the points to challenge.
