What's the difference between third-party and comprehensive car insurance in NZ?
In New Zealand, the main difference is whether your insurance covers damage to your own car as well as damage you cause to other people's property.
- Third-party insurance is cheaper and covers damage you cause to other people's cars or property.
- Comprehensive insurance covers damage to other people's property and damage to your own car, subject to your policy's terms and exclusions. Car insuranceMotor Insurance: What You Need to Know

There's also a middle option
Third-party, fire and theft gives you third-party protection plus cover for your own car if it is stolen or damaged by fire. It generally doesn't cover ordinary accidental damage to your car, such as a collision you cause. Car insuranceMotor Vehicle, Bike and Car Insurance
Which one should you choose?
- Third party: Worth considering if your car is older or has a low replacement value, and you could afford to repair or replace it yourself if it were damaged or written off.
- Comprehensive: Worth considering if replacing your car would be a financial burden, you have a newer or more valuable vehicle, or you want broader protection against unexpected damage.
- Third-party, fire and theft: A possible compromise if you're comfortable paying for your own accident repairs but want some protection against theft and fire.
One important point: comprehensive insurance doesn't mean everything is automatically covered. Check the excess (the amount you pay towards an accepted claim), exclusions, windscreen cover and whether your car is insured for agreed value or market value. Car insurance buying guideCar insurance
