Car insurance premiums have been climbing steadily across NZ - driven by rising parts costs, extreme weather events, and increasing theft. The good news? There are real, practical ways to pay less without gutting your cover. Here's how.
Your excess is the amount you pay out of pocket when you make a claim. It's one of the simplest levers you can pull to reduce your premium - and one of the most misunderstood.
Here's how it works: the higher the excess you're willing to pay, the lower your premium. That's because you're taking on more of the risk yourself, which means the insurer takes on less. Bumping your excess from $400 to $750, for example, could shave a noticeable chunk off your annual premium.
But there's a catch. You need to actually be able to afford that excess if you need to make a claim. There's no point saving $150 a year on your premium if a $1,000 excess would leave you scrambling to find the money after an accident. The sweet spot is an excess that's high enough to bring your premium down meaningfully, but low enough that you could pay it tomorrow without stress.
Most NZ insurers let you choose a voluntary excess on top of their standard excess. Some - like Tower and AA Insurance - offer online tools where you can slide the excess up and down and see the premium change in real time. It's worth playing with these to find the balance that works for you.
Our guide to insurance excess explains how excess works in more detail, including the difference between standard, voluntary, and special excesses (like the young driver excess that catches a lot of families off guard).
One of the most common ways Kiwis overpay for car insurance is by having more cover than they actually need. It sounds counterintuitive, but paying for full cover on a low-value car can be a poor deal.
Think about it this way. If your car is worth $3,000 and you're paying $900 a year for a policy with a $500 excess, the most you'd ever receive from a total loss is $2,500. After two years of premiums, you've already paid more than the car is worth. In this situation, third party fire and theft - or even third party only - may suit you better.
On the other hand, if you're driving a $30,000 car that you're still paying off, full cover isn't optional - it's essential. Your finance company will almost certainly require it, and the potential loss is far too large to absorb yourself.
The Sorted.org.nz car insurance guide breaks down when each level of cover tends to make sense. As a rough guide, many drivers find that once a car's value drops below $5,000 to $6,000, the sums start to favour stepping down from full cover.
Also keep in mind that your car's value drops every year. A policy that made perfect sense when you bought the car three years ago might not stack up today. Revisit your cover level at each renewal - not just the price.
Your no-claims bonus (NCB) - sometimes called a no-claims discount - is one of the biggest factors in how much you pay. It rewards you for not making claims, and the discounts can be substantial.
Most NZ insurers offer increasing discounts for each claim-free year, typically starting around 5% after one year and building up to 60% or more after five or six years. That's a massive chunk off your premium - and it's money you lose the moment you make a claim.
This is why it's sometimes worth thinking twice before claiming for minor damage. If a repair would cost $600 and your excess is $400, you'd only get $200 from your insurer - but making that claim could cost you your entire NCB. Over the next few years, the lost discount could add up to far more than the $200 you claimed.
Several insurers offer NCB protection as an add-on. This lets you make one claim (sometimes two) without losing your bonus. AMI and Tower both offer versions of this. Whether it's worth the extra cost depends on your situation, but for drivers with a large built-up discount, it can be a smart way to protect years of careful driving.
Good driving habits also affect your premium beyond just the NCB. A clean licence with no demerit points, no at-fault accidents, and no traffic convictions all signal to insurers that you're a lower risk. Waka Kotahi (NZTA) keeps your driving record, and insurers do ask about it.
The Canstar car insurance ratings pages have useful breakdowns of how different insurers handle NCB structures.
Typical NCB discount levels with NZ car insurers
Where you park your car and how you secure it have a direct effect on your premium. Insurers care about theft and damage risk, and anything you can do to reduce those risks can bring your costs down.
Parking in a locked garage overnight is one of the most effective things you can do. Insurers see a garaged car as significantly less likely to be stolen, vandalised, or damaged by weather. If you have a garage and you're not already telling your insurer about it, you could be missing out on savings. Even a carport or off-street driveway is typically rated better than parking on the street.
Vehicle security devices also make a difference. A factory-fitted immobiliser is standard on most modern cars, but if your vehicle has an aftermarket alarm, a steering lock, or a GPS tracker, it's worth mentioning when you get your estimates. Some insurers - including AA Insurance - factor security features into their pricing.
Where you live matters too. Urban areas with higher crime rates attract higher premiums. You can't change your address just to save on insurance, obviously - but if you've recently moved to a lower-risk area, make sure your insurer knows. Your address is a key rating factor.
For those concerned about the catalytic converter theft trend that's been hitting NZ hard, there are aftermarket cages and shields available that make theft more difficult. While these won't necessarily lower your premium directly, they reduce the chance of a claim - which protects your no-claims bonus and keeps your premiums stable over time. NZ Police have published guidance on protecting your vehicle from theft.
Here's something most people don't realise: staying with the same insurer year after year often costs you more, not less. It's called the loyalty tax, and it's a well-documented pattern across the NZ insurance market.
Insurers frequently offer their best pricing to new customers. Meanwhile, existing customers get their renewal notice with a price increase and just... pay it. The Consumer NZ team have highlighted this pattern repeatedly, and the ICNZ has acknowledged the issue.
The fix is simple: compare every year at renewal time. It takes 10 to 15 minutes to get estimates from several insurers, and the savings can be hundreds of dollars annually. On Compare.org.nz, you can get estimates from multiple insurers in one go, which takes the legwork out of the process.
Even if you end up staying with your current insurer, having competing estimates in hand gives you something to work with. Some insurers will match or beat a competitor's price if you call and ask. It won't always work, but it costs nothing to try.
Set a calendar reminder for two to three weeks before your renewal date. That gives you enough time to compare, consider your options, and make a switch if it makes sense - without any gaps in your cover.
Follow these steps every year when your renewal comes in
Set a reminder two to three weeks before your policy renews. This gives you time to compare without rushing or accidentally letting your cover lapse.
Check your current policy details - cover level, excess, agreed or market value, and any extras. Make sure it still matches your needs and your car's current value.
Use Compare.org.nz to get estimates from several insurers at once. Then visit individual insurer sites for actual quotes if any look promising.
Don't just compare on price. Match the cover type, excess, and key features (courtesy car, windscreen, roadside assist) to get a fair comparison.
If a competitor offers better value, switch before your renewal. Or call your current insurer with the competing price and see if they'll match it. Either way, you win.
Beyond the big moves, there are several smaller tactics that can chip away at your premium. None of them are game-changers on their own, but stack a few together and the savings add up.
Bundle your policies. Most NZ insurers offer multi-policy discounts if you hold more than one type of insurance with them - car plus contents, for example, or car plus house. The discount typically ranges from 5% to 15%. AMI, Tower, and AA Insurance all offer some form of multi-policy pricing.
Pay annually instead of monthly. Monthly payments are convenient, but they almost always cost more over the year. Insurers typically charge a loading of around 5% to 10% for the privilege of paying monthly. If you can swing the annual lump sum, it's worth doing.
Only insure what you need to. Are you paying for roadside assistance through your insurer and your AA membership? Do you have windscreen cover you've never used on a car that's barely worth the excess? Trim the extras you don't need.
Keep your details up to date. If you've moved to a safer area, reduced your annual kilometres, or your car now lives in a garage, tell your insurer. Any change that reduces your risk profile could reduce your premium.
Consider a restricted driver policy. Some insurers offer lower premiums if you limit who can drive the car to named drivers over a certain age. If you're the only one driving your vehicle, this can be a straightforward saving.
The Sorted.org.nz insurance hub has more tips on getting better value from all types of insurance, not just car.
If you're under 25 or recently got your licence, you already know car insurance isn't cheap for you. Younger drivers pay more because, statistically, they're involved in more accidents. It's not personal - it's just how the risk maths works. But there are still ways to keep costs under control.
Be a named driver on a parent's policy. If you're driving a family car, being added as a named driver to a parent's policy is almost always cheaper than taking out your own standalone policy. There will likely be a young driver excess on top of the standard excess (often $500 to $750 extra), but the overall premium will be lower than going it alone.
Choose your car carefully. The car you drive has a huge impact on your premium. A small, older, low-powered hatchback is going to cost far less to insure than a turbocharged import. Insurers look at the car's value, engine size, performance, safety rating, and theft risk. If you're buying your first car with insurance costs in mind, stick to something modest.
Build your no-claims history as early as possible. Every claim-free year builds your bonus and brings your premium down. Starting to build that history at 17 or 18 means you'll have a decent discount by the time you're in your mid-twenties. Avoid claiming for minor dings if you can cover them yourself.
Consider telematics or usage-based insurance. Some NZ insurers are starting to offer policies where your premium is influenced by how you actually drive - things like braking patterns, speed, and when you drive. If you're a careful driver, this can work in your favour even if your age works against you.
Take a defensive driving course. While not every insurer offers a direct discount for it, courses approved by Waka Kotahi (NZTA) can help reduce your demerit points and demonstrate responsible driving behaviour. Some insurers do ask about driver training, so it's worth mentioning.
