New Zealand car insurance comes in three main tiers. Understanding the difference helps you choose the right level for your vehicle and budget — and avoid being underinsured when you need to claim.
The Three Types of Car Insurance in NZ
1. Comprehensive
Comprehensive car insurance is the broadest cover available. It covers:
- Damage to your own vehicle — from accidents, regardless of fault
- Third-party property damage — damage you cause to other people’s vehicles or property
- Fire — if your car catches fire
- Theft — if your car is stolen
- Weather events — hail, flood, storm damage
- Accidental damage — including hit and run where the other party can’t be found
Comprehensive insurance is the most expensive option but provides the fullest protection.
2. Third-Party, Fire & Theft
This mid-tier option covers:
- Third-party property damage — damage you cause to other vehicles or property
- Fire — if your car catches fire
- Theft — if your car is stolen
It does not cover accidental damage to your own vehicle.
This option suits older vehicles where the repair cost might exceed the car’s value — but where you still want protection against catastrophic fire or theft loss.
3. Third-Party Only
The most basic option:
- Third-party property damage only — damage you cause to other people’s vehicles or property
No cover for your own vehicle at all. Best suited for older, lower-value cars where the owner can absorb the risk of losing the vehicle but wants protection against a large third-party claim (e.g., hitting an expensive car).
What’s NOT Covered by Any NZ Car Insurance
- Personal injury — covered by ACC regardless of fault; no car insurance covers personal injury in NZ
- Mechanical breakdown — wear and tear, mechanical failure
- Intentional damage by the driver
Which Cover Level Is Right for You?
Choose Comprehensive if:
- Your car is worth more than $10,000–$15,000
- You couldn’t easily afford to replace or repair your car after an accident
- Your car is financed — most lenders require comprehensive insurance
- You drive frequently or in high-traffic areas
- You’re a newer driver with higher accident risk
Choose Third-Party, Fire & Theft if:
- Your car is worth $3,000–$10,000 and you can absorb a partial loss
- Comprehensive premiums would cost more than the car’s depreciation each year
- You still want protection against catastrophic loss (theft, fire)
Choose Third-Party Only if:
- Your car is worth less than $3,000–$5,000
- You can financially absorb losing the vehicle entirely
- You primarily need protection against damaging an expensive vehicle in a car park or on the road
Market Value vs Agreed Value
Within comprehensive insurance, you’ll choose between:
Market value: The insurer pays what your car was worth on the open market at the time of the loss. Can be lower than you expect, particularly for depreciated vehicles.
Agreed value: You and the insurer agree on a fixed value at the start of the policy. This is what’s paid if the car is written off. More predictable, slightly more expensive.
Agreed value is generally preferable — especially if you’ve maintained or modified your vehicle and its market value is hard to determine.
No Claims Discount (NCD)
Most NZ comprehensive car insurers offer a no-claims discount — a reduction in your premium for each year without a claim. Building up NCD over multiple years can significantly reduce premiums.
Making a small claim can reduce your NCD and increase future premiums — sometimes costing more over 3–5 years than just paying the repair cost yourself.
