Car insurance renewal: a practical stay-or-switch checklist
In New Zealand, the best way to decide whether to renew your car insurance is to compare the total cost, cover, excess and claims experience — not just the premium.
My rule of thumb: give your current insurer a chance to compete, but don't stay purely out of habit. A cheaper policy can be a false economy if it leaves you with a large bill after an accident.
1. Your stay-or-switch checklist
Renewal review
0 of 9 checked
Compare the real annual costCheck the renewal premium, instalment fees, policy fees and any discounts. Compare the full 12-month cost, not just the weekly or monthly payment.
Match the level of coverCompare comprehensive, third-party fire and theft, or third-party-only cover on a like-for-like basis.
Check the excessCompare standard excesses and any additional excesses for young, inexperienced or unnamed drivers, and glass claims.
Check how your car is valuedLook at agreed value versus market value, the insured amount, and how a total loss would be settled.
Read the exclusionsCheck cover for theft, natural events, flooding, storms, modifications, accessories, business use and other drivers.
Review useful extrasCompare windscreen cover, roadside assistance, hire-car cover, new-for-old replacement and choice of repairer.
Consider the claims experienceCheck excess waivers, repair guarantees, claims support and any conditions that could complicate a claim.
Check your circumstancesUpdate drivers, annual kilometres, parking location, vehicle use, finance and any modifications.
Ask your current insurer to review the priceGet a competing quote and ask whether your insurer can improve the renewal offer or adjust your cover.
2. When should you stay or switch?
Stay with your insurer if…
- The premium is competitive for equivalent cover.
- Your excess, vehicle value and benefits still suit you.
- You trust the insurer's claims and repair process.
- A competing quote saves very little once differences in cover are accounted for.
Consider switching if…
- Another insurer offers comparable cover for meaningfully less.
- Your renewal premium has risen without a clear benefit.
- The alternative has a lower excess or better benefits at a similar price.
- Your current policy has exclusions, service issues or limitations that matter to you.

3. Compare the money, not just the premium
Use this quick calculation to assess a competing quote.
Enter annual figures in NZ dollars.

Estimated first-year saving from switching
$250
The alternative is cheaper before accounting for differences in cover and excess.
Remember: the alternative excess is $250 higher, so you'd need to be comfortable paying more if you claim.

4. New Zealand-specific checks before switching
- Vehicle value: Confirm whether the policy uses agreed or market value and whether the renewal value is still appropriate. Car insuranceCar Insurance Renewal Checklist
- Drivers and vehicle use: Make sure young or restricted-licence drivers, commuting, business use and modifications are accurately disclosed.
- Excess affordability: Choose an excess you could comfortably pay after an accident.
- Policy overlap: Arrange the new policy to start when the old cover ends, and obtain confirmation before cancelling the existing policy.
- Payment terms: Check whether monthly payments include additional fees and what happens to outstanding premiums if the car is written off. Car insuranceCar insurance: How to make a claim

5. The simplest next step
Get your renewal notice and two competing quotes. Compare the same cover level, vehicle value, excess and drivers, then ask your current insurer whether it can improve its offer.
If you share your renewal premium, car's approximate year and value, and whether you have comprehensive or third-party cover, I can help you work out what a reasonable stay-or-switch decision looks like for your situation.
