NZ Car Insurance Claim Denied? Here’s How to Win with IFSO (2026 Guide)

By InsurspyPublished 4 February 2026

Introduction

A declined car-insurance claim is not necessarily the final answer. In New Zealand, the practical starting point is to identify the exact policy clause, the facts the insurer relied on, and the evidence that supports or challenges those facts. You should then make a formal complaint to the insurer before considering its external dispute-resolution scheme.

This guide reflects the position as at 17 August 2026. It is general information, not legal or personalised insurance advice. In our editorial review, we recommend reading the current policy wording and schedule that applied on the date of loss, rather than relying on general descriptions of cover.

Start with the decline reason, not assumptions

Ask the insurer to give its decision and reasons in writing. Match its explanation against the policy wording, including the insuring clause, exclusions, conditions, definitions and endorsements. A claim can be refused because the loss falls outside the cover purchased, but a refusal should be assessed on the actual wording and circumstances.

Current consumer guidance identifies a range of issues that may lead an insurer to question or refuse a motor claim. They include an unsafe vehicle, alcohol or drugs, a licence-condition breach, an unnamed driver, business use of a private car, non-disclosure of convictions, modifications, incorrect main-driver information, previous accidents or claims, and inadequate care of the vehicle. None of these labels alone establishes an automatic outcome in every case.

Issue raised by the insurer	What to check	Useful evidence
Non-disclosure or incorrect information	What question was asked, your answer, application records, and whether the alleged statement was substantially incorrect and material.	Proposal/application, emails, call notes, renewal documents and driving or claims records.
Licence, WOF or vehicle condition	The exact exclusion, the vehicle condition, and whether the alleged circumstance caused or contributed to the loss.	Licence status, WOF and service records, photographs, assessor reports and crash evidence.
Business or delivery use	The policy definition of permitted use and what the vehicle was being used for at the time.	Policy schedule, work arrangements, trip records and communications with the insurer.
Care, security or theft	The policy's security and reasonable-care requirements, and the facts immediately before the theft or damage.	Police report, keys information, photographs, CCTV if available and witness details.
Amount offered or repair decision	The insurer's valuation, repair scope, excess and any expert reports.	Quotes, invoices, independent reports and a clear calculation of the amount in dispute.

Common dispute areas: how to assess them carefully

Disclosure and incorrect statements

As at this guide's date, the Insurance Law Reform Act 1977 remains relevant to non-life insurance. It provides that an insurance contract cannot be avoided solely because of a statement unless the statement was substantially incorrect and material. Materiality turns on whether it would have influenced a prudent insurer's premium or decision to take or continue the risk on substantially the same terms.

That does not mean every omission is harmless, nor does it mean an insurer can simply rely on a minor discrepancy. Preserve the original questions and your answers. If the insurer says a fact would have changed its underwriting decision, ask it to explain the basis for that position.

WOF, licence conditions and causation

A WOF or licence issue may give an insurer a policy-based reason to investigate a claim, particularly where vehicle safety or licence conditions are relevant. It is not accurate to describe either issue as a universal statutory exclusion from insurance.

Section 11 of the Insurance Law Reform Act 1977 may be important for a qualifying increased-risk exclusion. Where it applies, the insured must prove on the balance of probabilities that the excluded event or circumstance did not cause or contribute to the loss. A published motor-insurance case involving a suspended driver illustrates that this can be highly fact-specific: the exclusion could not be relied on where the suspension did not cause or contribute to the accident. It is an example, not a promise of cover in a WOF, licence or driver-exclusion dispute.

There is no general rule in the cited guidance that guarantees cover because a WOF was only recently expired. Check the wording, condition of the vehicle, causation evidence and whether section 11 may apply.

Private vehicles used for work

Using a private vehicle for deliveries, trade work or another business purpose can create a coverage issue. Consumer guidance says work vehicles need business insurance and private-car cover may not respond to work-use damage. Check the permitted-use definition in your own policy and tell the insurer how the car is used; do not assume a private policy includes every side activity.

Vehicle security and care

A theft claim may be jeopardised if the insurer says reasonable care was not taken, for example where a vehicle was left unsecured with keys available. The outcome depends on the wording and evidence. Avoid characterising this as an automatic policy voiding event; instead, establish exactly what occurred and which condition the insurer says was breached.

Make a focused internal complaint

Before escalating externally, send a written formal complaint to the insurer's complaints team. State that you dispute the claim decision, identify the decision date and claim number, and set out the outcome you seek. Attach a short timeline and the documents that matter. Keep copies of every email, letter, photograph, report and call record.

For a formal complaint under the Fair Insurance Code, the insurer should acknowledge the complaint within five business days and respond within 10 business days. If it cannot resolve the complaint within two months, it should advise you of your external dispute-resolution rights.

Request the complete reasoning: ask for the relied-on clauses, relevant facts, reports and valuation or repair calculations.
Respond to each point: distinguish facts you accept from facts you dispute, and explain why your evidence matters.
Ask for a review: request review through the insurer's formal complaints process, not merely another claims call.
Set out a practical remedy: for example, reconsideration, payment, a repair reassessment, a corrected record or a written explanation.
Track dates: retain proof of when the formal complaint was sent and every response received.

When we compare policy information, we also encourage motorists to check whether future cover matches their actual use, drivers and vehicle details. Our car insurance guide can help with questions to ask when reviewing cover, but it cannot determine an existing claim.

When IFSO may be able to help

Do not assume IFSO is the automatic route. First ask the insurer which approved dispute-resolution scheme it belongs to. IFSO can consider eligible complaints about an IFSO participant, including alleged breaches of contract, statutory obligations, industry codes or relevant industry practice. It cannot consider a complaint by an uninsured third party about that insurer's claim.

For an eligible IFSO matter, you must first complain to the participant. You may take the complaint to IFSO if the insurer has not advised that deadlock has been reached within two months, or if you receive a written deadlock decision that you reject. Following written deadlock, the ordinary filing deadline is three months. IFSO may extend this by up to nine months in exceptional circumstances. Its general outside limit is six years from when you became aware of the relevant facts or events.

The service is free for customers. IFSO can use alternative dispute resolution or a decision process and considers what is fair and reasonable in the circumstances, taking account of applicable law, natural justice, relevant industry practice and applicable codes. Its current direct-compensation limit is up to $500,000 plus GST where applicable, with up to $10,000 plus GST in special compensation, as well as interest where applicable. It may also require records to be corrected or changed where possible.

IFSO may issue an assessment, recommendation or award. An award becomes binding on both parties only if the complainant agrees in writing to accept it in full and final settlement. If you reject an IFSO outcome, alternative court action may be available, but IFSO must stop considering the complaint once court action is taken. Consider independent legal advice before choosing a court route or accepting a full-and-final settlement.

Current legal position in 2026

The Contracts of Insurance Act 2024 has been enacted, but it is not in force on 17 August 2026. Its commencement is scheduled for 15 November 2027. For a 2026 motor claim, do not assume that the Act's future reasonable-care disclosure duty or proportionate-remedies framework already applies.

The Fair Trading Act may also be relevant where an insurance sale or advertisement involved misleading or deceptive conduct, false claims, or omission of important information that created a false impression. However, it does not automatically decide whether a particular accident, theft or damage is covered under the policy. Keep the insurance-contract dispute and any concern about advertising or sales representations clearly separated in your complaint.

Insurance Claims Register: check the record, not a "blacklist" label

The Insurance Claims Register is used by participating insurers to help detect and prevent fraud, including non-disclosure and duplicate claims. It is not a universal insurance-decline blacklist, and a register entry does not by itself determine your future ability to obtain cover. You may request access to information held about you and seek a warranted correction. If the register is part of your dispute, identify the precise entry you say is inaccurate and provide documents supporting the correction.

Practical Takeaway

Act promptly, stay factual and use the formal process. Obtain the written decline reasons; compare them with the policy and your evidence; lodge a written internal complaint; and ask which dispute-resolution scheme applies. If the insurer is an IFSO participant and the matter is eligible, watch the two-month, three-month and six-year time limits carefully. A declined claim can be stressful, but a clear evidence-led complaint is more useful than broad accusations.
