What major exclusions should I understand before deciding between NZ car policies?
When comparing New Zealand car insurance policies, the exclusions are often where the biggest differences appear. A cheaper premium may come with narrower cover, so check the policy wording rather than relying only on labels like “comprehensive”. Consumer Protection
Key exclusions to understand:
Mechanical failure and wear and tear
- Standard car insurance usually covers sudden accidental damage, not an engine failure, worn clutch, failing gearbox, rust, corrosion, or gradual deterioration. Separate mechanical breakdown cover (if offered) is a different product. Canstar
Driver restrictions
- Claims may be affected if the person driving is not listed or permitted under the policy, does not hold the correct licence, or breaches licence conditions. Check rules around young drivers, restricted licences, and occasional drivers. Consumer Protection
Alcohol, drugs, and unsafe driving
- Policies commonly exclude claims where the driver is impaired by alcohol or drugs, driving dangerously, racing, or using the vehicle for illegal purposes. ICNZ | Insurance Council of New Zealand
Business or commercial use
- A private-use policy may not cover using your car for activities such as paid passenger transport, deliveries, or other business purposes unless you have told the insurer and the policy allows it. Consumer Protection
Unnotified modifications
- Suspension changes, performance upgrades, cosmetic modifications, or other alterations may need to be disclosed. Failure to tell the insurer can affect a claim. Consumer Protection
Unroadworthy vehicles
- Damage may not be covered if the vehicle was unsafe to drive or did not meet required standards, especially where the condition contributed to the loss. Consumer Protection
Pre-existing damage
- Damage that existed before the policy started is generally excluded. ICNZ | Insurance Council of New Zealand
Tyres and normal running costs
- Tyre damage from ordinary wear, punctures, or deterioration is often excluded unless it forms part of a wider insured accident. ICNZ | Insurance Council of New Zealand
Incorrect fuel
- Putting the wrong fuel in the vehicle is commonly excluded or only covered if the policy specifically provides a benefit for it. ICNZ | Insurance Council of New Zealand
Losses beyond the vehicle damage
- Many policies do not cover things like loss of income, loss of vehicle value after repairs, or other indirect financial losses unless specifically included. NZI Site
Contents and personal belongings
- Items left inside the car may have limited cover or no cover under a motor policy, depending on the insurer and policy. ICNZ | Insurance Council of New Zealand
Before choosing a policy, compare:
- Excess amounts (including young-driver or unnamed-driver excesses).
- Agreed value vs market value payout basis. Consumer Protection
- Named driver rules.
- Repairer choice and whether genuine parts are used.
- Optional extras such as windscreen cover, roadside assistance, rental car cover, or new-car replacement.
The most important exclusions are usually the ones that match how you actually use your car: who drives it, whether it is used for work, where it is parked, and whether it has any modifications. Consumer Protection
