ChatGPT · New Zealand
We have one good family car and one old runabout. Could we insure them differently to keep the cost down?
Yes — in New Zealand, insuring your good family car comprehensively and putting your old runabout on cheaper third-party cover is often a sensible way to reduce your insurance costs. You don't need to insure both cars to the same level.
The key is to protect the car that would be expensive to replace, while avoiding paying for cover on the old car that might not be worth much. New Zealand's Consumer Protection guidance specifically recommends considering third-party or third-party, fire and theft cover for lower-value vehicles. Car insuranceCar insurance buying guide
How I'd insure the two cars
1. Good family car
Keep comprehensive
Keep comprehensive insurance if replacing the car would be a significant financial burden. It generally covers accidental damage to your own car, theft and damage you cause to other people's property, subject to policy terms.
If this is the car you rely on every day for work, school and family trips, the extra protection is usually worthwhile.
2. Old runabout
Consider third-party only
If the car is worth relatively little and you could afford to replace it yourself, third-party-only insurance is worth pricing up.
It protects you against liability for damage you cause to other people's vehicles or property, but doesn't pay to repair or replace your own car after an accident.
You could instead choose third-party, fire and theft for the runabout if you'd like protection if it's stolen or catches fire. It usually costs more than third-party-only cover. Car ownership and insuranceAA Third Party Car Insurance Quote Online
Other ways to bring the premiums down
- Increase the excess on the family car if you have enough savings to cover it after an accident. A higher excess can lower the premium.
- Limit named drivers where appropriate. Some insurers offer lower premiums when younger drivers are excluded.
- Tell the insurer how the runabout is used. If it does low mileage or is only used occasionally, ask whether that changes the price or available cover.
- Compare at least three insurers. Get quotes for the same cover levels and excesses, and ask whether combining car, house and contents insurance earns a discount.
- Review optional extras. Check whether you need roadside assistance, rental-car cover or other add-ons on both policies. Car insuranceInsuranceCar insurance buying guide
Let's work out what might suit you
If you tell me a little about the two cars, I can help you decide which cover is likely to offer the best value.

Estimates are fine — you don't need exact valuations.
One important consideration: if you couldn't comfortably afford to replace the runabout tomorrow, don't automatically drop all cover for damage to your own car. The cheapest policy isn't always the best-value policy.
