Comprehensive vs third party car insurance in New Zealand

What does each level of car insurance cover?

All three levels pay for damage you cause to other people's vehicles and property. Third party only stops there. Third party fire and theft adds your own car being stolen or damaged by fire. Comprehensive adds accidental damage to your own car, including in a crash you caused.

Every insurer on this site uses the same three names, so the names are worth taking literally. “Third party” means somebody else — their car, their fence, their shopfront. Tower's own page puts the base level as plainly as anyone:

“Third party cover: This option pays for damage you cause to other people's car and property, but not your own.”

Add fire and theft and you have the middle level. Trade Me Insurance describes that one this way:

“Third Party Fire & Theft: Pays for damage you cause to other people's cars and property, but not your own. You're also covered for loss through fire or theft.”

Comprehensive adds the thing neither third party level does: accidental damage to your own car, including in a crash you caused.

Do I need comprehensive car insurance?

If the car were written off tomorrow and there were no payout, could you replace it? That is the whole comprehensive decision, and nobody else can answer it for you. It is not really an insurance question: it is a question about your own savings and what losing the car would cost you in the weeks afterwards.

The reason people find this hard is that it is not really an insurance question. It is a question about your own savings and what losing the car would cost you in the weeks afterwards. [The questionnaire](/which-cover) asks it, and five other questions, and shows you which levels answer which worry — without asking for your name, your email or your registration.

When is the choice already made for me?

Three situations take it out of your hands. A car on finance, where the lender commonly requires comprehensive for the life of the loan. A car used for work, where a private policy may not respond at all. And an insurer that sells one level only — Cove states all its car policies are comprehensive.

• The car is on finance. Lenders commonly require comprehensive cover for the life of the loan, and often require the lender to be recorded as an interested party on the policy. That requirement lives in your loan agreement. Read it there.
• The car is used for work. Private car policies commonly exclude carrying goods or passengers for hire or reward. If the car does courier work, deliveries or ride-share, the level of cover is not the first question — whether a private policy responds at all is.
• One insurer only sells one level. Cove states on its own page: “At this time all Cove car insurance policies are for comprehensive cover.” So the choice of level and the choice of insurer are not always independent.

What does choosing comprehensive not settle?

Three things, and they are where claims actually go wrong. Whether the car is insured for an agreed value or its market value, which decides what a write-off pays. The excess, and every additional excess stacked on it. And who is allowed to drive the car before cover is affected.

Choosing comprehensive settles one thing and leaves three open:

1. [Agreed value or market value](/guides/agreed-value-vs-market-value). Both exist in this market. It decides what gets paid when the car is written off.
2. [The excess, and every additional excess](/guides/car-insurance-excess-explained). One wording read for this site names six kinds of additional excess that can sit on top of the standard one.
3. Who is allowed to drive it. Some policies cover anyone with your permission; others cover only the people named on the schedule; one excludes drivers under 21 outright.
