How do I compare options for a car that standard insurers may not cover?
If you have a car that standard insurers may not cover, the best approach in New Zealand is to compare specialist insurance providers, the exact cover offered, and the conditions they impose — not just the premiums.
Cars that can be difficult to insure include heavily modified vehicles, imports, high-performance or classic cars, vehicles with previous damage or unusual repair histories, and cars used for motorsport or other specialist purposes.
The key is to find a policy that explicitly accepts your particular vehicle and intended use, rather than buying a cheap policy that may not cover it when you need to claim.
1. Compare your insurance options
| Option | Best suited to | What to check |
|---|---|---|
| Standard comprehensive insurance | Cars that meet mainstream underwriting rules | Whether modifications, imports or previous damage are accepted |
| Specialist or modified-car insurance | Performance cars, modified vehicles and unusual builds | Agreed value, modification declarations and specialist repair conditions |
| Classic or collector-car insurance | Older, collectible or limited-use vehicles | Mileage limits, storage requirements and restrictions on daily use |
| Third-party, fire and theft | Cars where comprehensive cover is unavailable or too expensive | Theft, fire, liability and exclusions for your vehicle type |
| Third-party property damage | Owners mainly concerned about damage they cause to other people's property | Your own vehicle's repair or replacement costs are generally not covered |
These categories can overlap. A specialist insurer may offer comprehensive cover, while some mainstream insurers may accept certain modified or imported cars after assessment.

3. Compare the details that determine whether a policy is worthwhile
When you receive quotes, compare these points side by side.
| What to compare | Why it matters |
|---|---|
| Acceptance in writing | Confirm the insurer accepts the exact make, model, year, modifications and intended use. |
| Agreed value vs market value | An agreed value can be especially useful for a modified or collectible car, provided the accepted value includes the relevant modifications. |
| Excess | Check the standard excess and any additional excesses for young drivers, theft or particular circumstances. |
| Repair arrangements | Find out whether you can choose your own specialist repairer and whether rare parts are covered. |
| Usage restrictions | Check daily driving, annual mileage, track days, storage and security requirements. |
| Exclusions | Read exclusions relating to modifications, mechanical failure, racing, previous damage and roadworthiness. |
| Total cost | Compare the annual premium plus realistic excesses and any mandatory security or storage costs. |
New Zealand's Consumer Protection guidance stresses that modifications and other relevant details must be disclosed. Incorrect or incomplete information can jeopardise a claim. Car insuranceMotor Insurance: What You Need to Know
4. Get comparable quotes
Give each provider the same information:
- Registration, make, model and year.
- Import status and modification details, including engine, suspension and wheels.
- Estimated value, supported by photographs, receipts or a valuation where appropriate.
- Main driver, driving history and intended annual mileage.
- Whether the car is a daily driver, weekend car, project or track vehicle.
- Previous insurance refusals, cancellations or claims, where applicable.
Ask each provider to quote for the same level of cover and vehicle value. Get the exclusions and accepted modifications confirmed in the policy schedule or other written documentation before relying on the cover.
