Car insurance isn’t legally required in New Zealand — but driving without cover is a significant financial risk. If you cause an accident and damage someone else’s vehicle or property, you’re personally liable for those costs. A single at-fault collision can easily cost $10,000–$50,000 in third-party damage.
If your car is worth over $5,000, comprehensive insurance is almost always worthwhile. If your car is worth less than $3,000, third party only may be sufficient. Comprehensive cover runs $600–$1,500/year for most drivers. AA Insurance, AMI, and State are the most popular NZ providers — but Youi and Trade Me Insurance are worth comparing for competitive pricing.
The Three Types of Car Insurance in NZ
1. Comprehensive
Covers damage to your own vehicle and damage you cause to others’ property.
- Your car damaged in an accident (including your fault)
- Fire, flood, storm, hail damage
- Theft or attempted theft
- Windscreen damage (often included or at low excess)
- Third-party liability
Cost: ~$600–$1,500/year for a standard car and driver profile
2. Third Party, Fire and Theft
Covers damage to others’ property plus fire and theft of your own vehicle. Does not cover your own car in a collision.
Cost: ~$350–$600/year
3. Third Party Only
Covers only damage you cause to other people’s vehicles and property. No cover for your own vehicle.
Cost: ~$200–$400/year
Which Type Should You Choose?
| Car Value | Recommended Cover |
|---|---|
| Under $2,000 | Third party only — repair cost likely exceeds car value |
| $2,000–$5,000 | Third party fire & theft, or check comprehensive cost |
| $5,000–$15,000 | Comprehensive — strongly recommended |
| Over $15,000 | Comprehensive — essential |
| Financed (on loan) | Comprehensive — usually required by lender |
What Affects Your Premium
| Factor | Impact |
|---|---|
| Driver age | Under 25 pay significantly more (2–3× average) |
| Claims history | Any claims in past 3–5 years increase cost |
| Car make/model | Sports cars, imports, high-powered vehicles cost more |
| Car value | Higher insured value = higher premium |
| Location | Urban areas (especially Auckland) cost more |
| Excess chosen | Higher excess → lower premium |
| Use type | Business use often costs more than private use |
| Parking | Garaged vs street-parked affects theft risk |
Agreed Value vs Market Value
- Agreed value: You and the insurer agree upfront what the car is worth. If written off, you get that agreed amount. More certainty — slightly higher premium.
- Market value: Insurer pays what the car is worth at the time of the claim. If your car has depreciated, the payout may be less than you expect.
For newer or high-value cars, agreed value is usually recommended.
NZ Car Insurance Providers Compared
| Provider | Strengths | Watch Out For |
|---|---|---|
| AA Insurance | Strong claims service, AA member discounts, well-known | Can be pricier than some competitors |
| AMI | Good value, established brand | Part of IAG group |
| State | Competitive online pricing, easy online management | Part of IAG group |
| Youi | Personalised pricing, may be cheaper for low-risk profiles | Detailed application required |
| Tower | Tech-focused, online management | Smaller scale than AA/IAG |
| Trade Me Insurance | Often cheapest option | Less known claims service |
Note: AA Insurance, AMI, and State share IAG as parent company. They can price differently — always compare all three.
Tips to Reduce Your Premium
- Increase your excess. Going from $300 to $750 excess can reduce premium by 15–30%.
- Bundle with contents or home insurance. Most insurers offer 5–15% discount.
- Choose market value instead of agreed value if the car is older.
- Ask about loyalty discounts — many insurers reward multiple years claim-free.
- Be accurate about use. If you mainly use the car for private driving, don’t list it as business use.
- Add a named driver restriction. Excluding under-25 drivers from the policy can reduce cost if applicable.
- Compare quotes online. Premiums vary widely for the same profile — comparison sites or direct quotes from 3–4 insurers is time well spent.
Young Drivers — What to Know
Drivers under 25 face significantly higher premiums. Options:
- Look at being named on a parent’s policy (check the implications for the named driver excess)
- Youi sometimes offers competitive pricing for young drivers with clean records
- A dashcam may reduce the excess in some disputes
- Consider a higher-excess, lower-premium policy and self-fund minor claims
What Happens After an Accident
- Move vehicles to safety if possible
- Exchange details (name, phone, registration, insurer) with all parties
- Take photos of damage, road conditions, and positions
- Notify your insurer promptly — most have 24-hour claims lines
- Don’t admit fault at the scene — this can affect your claim
