Wait, That’s Not Covered? 7 Standard Car Insurance Exclusions in NZ (2026 Guide)

Introduction

“Comprehensive” car insurance is broad protection, not a promise that every loss will be paid. In our editorial review, the most important distinction is between what a cover type generally insures and the conditions, exclusions and driver details that apply to a particular policy.

As at 17 August 2026, Consumer Protection NZ notes that insurers may question or refuse claims involving matters such as unsafe vehicles, alcohol or drugs, licence-condition breaches, named-driver restrictions, undisclosed information, inadequate care and private vehicles used for business. The outcome is never automatic: the wording, schedule, evidence and facts matter.

ACC may help with eligible personal injuries caused by accidents, but it is not a vehicle-repair scheme. For protection for the car and damage it causes to other property, compare the policy documents behind the car insurance options, not simply the cover label or premium.

Cover type is only the starting point

These are general descriptions, not a coverage guarantee. Benefits, exclusions, driver eligibility and excesses can differ between insurers, product versions and your policy schedule.

7 common exclusions and claim-decline risks

1. Driving outside licence conditions or driver restrictions

A claim can be at risk if the driver breaches a licence condition, or if the policy has named-driver restrictions and the driver is not eligible. Do not assume that a friend, flatmate or family member has the same cover as the policyholder simply because they had permission to use the car.

A licence breach does not automatically decide every claim. An FSCL case study explains that section 11 of the Insurance Law Reform Act 1977 may prevent reliance on an exclusion if the insured proves, on the balance of probabilities, that the breach did not cause or contribute to the loss. This is a fact-specific issue, not personalised legal advice.

2. Alcohol, drugs and related conduct

Alcohol- and drug-related exclusions are common, but their tests are wording-specific. For example, State’s current policy wording identifies circumstances including a driver being over the legal alcohol limit, refusing a legally required breath or blood test, being impaired by alcohol or drugs, or unlawfully leaving the scene.

Evidence matters. In an FSCL alcohol-exclusion case, suspicion and BAC estimates alone were insufficient to establish impairment. That does not mean cover will apply in every disputed case; it means an insurer must apply its wording to the available evidence.

3. Intentional, reckless or prohibited driving

Private car insurance is designed for accidental events, not deliberate damage or reckless conduct. Current insurer wording can exclude intentional or reckless acts, and private-use policies may also exclude track, race or similar use. Check the exact definitions in your own policy before attending a track event or using the vehicle in a high-risk activity.

4. An unsafe or unroadworthy vehicle

An expired WoF is not, by itself, the whole insurance test. Vehicle condition can nevertheless be central where a defect or unsafe use contributed to the incident. For example, State’s current unsafe/unroadworthy exclusion includes tests about whether the condition or use contributed to the incident and whether the driver should have known it could result in a claim.

Keep up with maintenance and act on known safety issues. Read the unroadworthy-vehicle clause rather than relying on a broad assumption that a current WoF alone resolves every insurance question.

5. Undisclosed modifications or material information

Tell the insurer about modifications and relevant changes, including changes to the main driver, previous claims or convictions where asked. Undisclosed modifications can affect whether the vehicle or modification is covered and can affect a claim.

Consumer Protection NZ says customers should provide complete, honest, up-to-date and relevant information when applying, renewing, claiming and when circumstances change. Cancellation from the policy start is limited to omitted information that was material and would have affected the insurer’s underwriting decision or premium. Do not assume every omission has the same consequence.

6. Wear, corrosion and mechanical breakdown

Ordinary wear, rust or corrosion, gradual deterioration, and certain mechanical, electrical or electronic breakdowns are commonly outside standard car cover. The treatment of resulting accident damage can depend on the wording. Comprehensive insurance is therefore not the same as a maintenance plan or a blanket engine-failure guarantee.

7. Using a private car for undeclared business or income-producing work

Private-car cover may not extend to delivery, courier work, ride-share, taxis, fare-paying passengers or other income-producing use. AMI’s guidance, for example, distinguishes private social, recreational, domestic and commuting use from delivery, courier, ride-share, fare-paying passenger, some business and track/race use.

Confirm the exact use with the insurer before starting the activity. Depending on the insurer and use, the solution may be an endorsement to a private policy or commercial cover.

Reasonable care is an ongoing policy condition

Many policies require reasonable care to prevent loss. Leaving a vehicle unlocked or leaving keys accessible can put a theft claim at risk, but the decision remains dependent on the policy and facts. Practical precautions are straightforward: secure the vehicle, take the keys, keep it maintained and report changes in how it is used.

What to check before you buy or renew

What to Do Next

1. Read your current policy schedule alongside the full wording, especially the exclusions and “your responsibilities” sections.
2. Ask the insurer to confirm any non-standard driver, modification or business-use situation in writing.
3. Keep information current at renewal and when your circumstances change.
4. If a claim is declined and you do not understand why, ask for the relevant policy clause and reasons. Consider independent consumer or dispute-resolution support where appropriate.

In our research, section 11 of the Insurance Law Reform Act 1977 can still be relevant to certain disputes in 2026. The broader Contracts of Insurance Act 2024 reforms should not be treated as the operative general motor-insurance law at this date; uncommenced provisions are due no later than 15 November 2027 unless brought into force earlier.

This guide provides general information only, not legal, financial or insurance advice. Your own policy wording, schedule and circumstances control.
