New Zealand has no compulsory third-party car insurance — only compulsory ACC levies (which cover injury, not vehicle damage). That means if an uninsured driver hits you, you have limited legal recourse for vehicle damage. Choosing the right insurer and cover level is a genuine financial decision.
Best overall: AA Insurance (strong claims reputation, wide coverage). Cheapest: Trade Me Insurance or Youi (varies by profile — get quotes from both). Best for young drivers: Youi (rated on behaviour, not just age). Best for older low-value cars: third-party only from AMI, State, or Trade Me Insurance (~$200–$400/year).
NZ Car Insurance Types
| Type | What it covers | Typical annual cost |
|---|---|---|
| Comprehensive | Your car (accident, theft, fire, weather), third-party vehicles and property | $600–$1,500 |
| Third party, fire & theft | Your car if stolen or fire-damaged; third-party damage | $350–$700 |
| Third party only | Third-party vehicles and property only (not your own car) | $200–$400 |
Key NZ context: ACC covers any injury in a road accident. Car insurance covers the vehicle damage — your car and others'.

AA Insurance — Best Overall
Verdict: Best for reliability and claims confidence. Strong claims culture.
AA Insurance is a joint venture between the New Zealand Automobile Association and IAG. It’s consistently rated well for claims handling and has the AA brand’s consumer trust behind it. AA members get a discount on premiums.
Strengths
- Strong claims reputation — consistently positive customer feedback
- AA member discount (~5–10%)
- Wide coverage options and add-ons
- 24/7 claims line
- Agreed value option available
Weaknesses
- Not the cheapest option (you pay for claims service quality)
- IAG-owned (not NZ-owned)
- No specific young driver programme
Best for: People who prioritise claims experience over price. Families with multiple vehicles (bundling discounts).
AMI Insurance — Established and Competitive
Verdict: Solid mid-range option. Good for multi-policy bundling with home/contents.
AMI has been in NZ since 1926. Owned by IAG. Known for reliability and competitive bundling discounts when you hold home, contents, and car together.
Strengths
- Strong bundling discounts (up to 15% for multiple policies)
- Long NZ history and recognisable brand
- Good for regional NZ customers
- Competitive base rates
Weaknesses
- Digital experience less modern than Youi or Trade Me
- Not the cheapest for standalone car insurance
Best for: Homeowners who want to bundle home, contents, and car with one insurer.
State Insurance — Competitive and Established
Verdict: Reliable, competitive pricing, long NZ history.
State Insurance has operated in NZ since 1905. Also owned by IAG. Very similar to AMI in product offering — good value, especially for bundling. Check both AMI and State quotes as pricing can vary by profile.
Strengths
- Competitive pricing for many profiles
- Long NZ history (established 1905)
- Good coverage options
- Multi-policy discounts
Weaknesses
- IAG-owned (same parent as AMI and AA Insurance)
- Less differentiated from AMI
Best for: Budget-conscious buyers who want an established brand.
Youi — Best for Lower-Risk Drivers
Verdict: Personalised rating model rewards good drivers. Best for those who don’t fit standard risk profiles.
Youi uses a more detailed questionnaire to assess risk personally rather than relying purely on age/gender brackets. This means low-mileage drivers, drivers with no claims history, and older drivers in safe suburbs often get significantly cheaper quotes.
Strengths
- Personalised risk rating — low-risk drivers often pay less
- Good digital experience
- Competitive pricing for clean-record drivers
- Active in telematics-style usage-based underwriting
Weaknesses
- Can be more expensive for high-risk profiles
- South African-owned (OUTsurance Group)
- Less established NZ brand history
Best for: Drivers with clean records and lower annual mileage. Worth getting a Youi quote alongside AA Insurance.
Tower Insurance — NZ-Listed, Competitive
Verdict: NZ-managed insurer with competitive pricing. Worth including in your comparison.
Tower is listed on both the NZX and ASX. It’s one of the few insurers with genuine NZ management and ownership interest. Competitive pricing and a straightforward product range.
Strengths
- NZ-listed (NZX/ASX)
- Competitive pricing
- Straightforward claims process
- Risk-based pricing model (similar to Youi)
Weaknesses
- Smaller company than IAG-backed competitors
- Less brand recognition
Best for: Those who prefer NZ-managed companies. Often competitive for Christchurch and natural disaster risk areas.
Trade Me Insurance — Online-First, Often Cheapest
Verdict: Frequently the cheapest for equivalent cover. Best for online buyers who don’t need branch access.
Trade Me Insurance is underwritten by IAG but distributed online only. Lower overhead costs translate to lower premiums for many profiles. Best compared directly against others.
Strengths
- Often the cheapest comprehensive quote in online comparisons
- Backed by IAG (same claims infrastructure as AA/AMI/State)
- Simple online purchase and management
- Easy to compare via Trade Me platform
Weaknesses
- Online-only (no branch or phone-first service)
- Less personalised customer service
- Same underlying insurer as AA/AMI/State (IAG) — just cheaper distribution
Best for: Budget-conscious buyers comfortable with online-only service. Get a Trade Me quote alongside AA — the gap is often 15–25%.
Best Car Insurance by Profile (2026)
| Your profile | Recommended insurer | Why |
|---|---|---|
| Best overall | AA Insurance | Claims reputation, strong coverage |
| Cheapest comprehensive | Trade Me Insurance or Youi | Get quotes from both |
| Young driver (under 25) | Youi | Personalised rating can undercut age-penalised pricing |
| Multi-policy bundling | AMI or State | Best bundling discounts for home + contents + car |
| Older/low-value car | Third party — AMI, State or Trade Me | Comprehensive not worth it once car value drops below ~$5k |
| NZ-managed preference | Tower | NZX-listed, NZ management |
| High-risk profile | AA Insurance or State | Broader underwriting appetite |
How to Reduce Your Car Insurance Premium
- Increase your excess — a $1,000 excess vs $400 can save 15–25% annually
- Agreed value vs market value — market value is cheaper but pays less at claim
- Multi-policy discount — bundle home/contents/car with one insurer
- No-claims discount — maintain a clean record; most insurers reward it
- Garage your car — reduces theft and weather risk
- Lower annual mileage — some insurers (Youi) discount for low-mileage drivers
- Named drivers only — excluding unnamed young drivers reduces premium
When Is Third-Party-Only Enough?
Comprehensive insurance is not cost-effective for every car. A rough guide:
| Car value | Recommended cover | Reasoning |
|---|---|---|
| Under $3,000 | Third party only | Premium may exceed payout |
| $3,000–$8,000 | Third party fire & theft | Theft protection without full comp cost |
| $8,000–$15,000 | Comprehensive or TPFT | Weigh annual premium against car value |
| Over $15,000 | Comprehensive | Replacement cost justifies premium |
How to Get the Best Quote
- Get quotes from at least 3 providers directly online
- Always compare AA Insurance, Trade Me Insurance, and Youi — they represent the pricing range
- Check excess options at each level — the premium difference is often significant
- Ask about multi-policy discounts if you also need home or contents insurance
