Summary
  • If your car insurance is coming up for renewal, the quote you've received for the next 12 months may seem expensive. Cheaper car insurance is more than likely if you're prepared to get a few online quotes.
  • And to make sure you don't over-insure (and overpay) for car insurance, it's essential to know the value of your car.
  • Our car insurance calculator, which you can find after steps 1-3, is a proven (and easy) three-step process to get the best deal.

Step 1 - Know how car insurance is calculated

Car insurance costs depend on your unique circumstances. The final price you see is influenced by many factors, including your driving history, car, where you live, your age and your gender. Insurers use this information and all of their data to predict the risk of you making a claim. The bigger the risk, the higher the cost of car insurance (and vice versa). 

Significant risk factors include:
  1. Young drivers (who don't have much driving history and, for many reasons, are statistically more likely to make a car insurance claim than older drivers)
  2. Modified or unusual vehicles (as high-performance usually means a higher chance of accidents and/or expensive parts for repairs)
  3. Where the car is stored - a locked garage is the safest, whereas on-the-road in an area with a high crime is the riskiest for an insurer. Car insurance usually costs more when the car's location is less secure.

Step 2 - Know the value of your car

To make sure you're covered correctly, knowing the value of your car is essential. There's no sense in buying too much insurance – it's a waste of money. But if you don't buy enough insurance, you could be on the hook for the difference between what your insurance pays and the cost of damages, which could be financially destructive.

Getting a reliable car valuation can be problematic. Our Car Valuations tool uses leading market data and is free to use.

Step 3 - Compare car insurance

Once you know the value of your car and understand the risk factors, the best thing to do is compare car insurance quotes. Generally, most insurers offer the same level of cover (see our AMI vs AA Insurance vs Cove vs State vs Tower vs Trade Me Insurance comparison of policies). 

Our guide to car insurance outlines everything you need to know when getting quotes from major insurers (AMI, Tower, State, AA etc.). Our car insurance directory lists 38 car insurers in New Zealand, some of which provide online quotes.

Know this:
  1. Driving safely and not making claims makes you popular with car insurers. If you have claimed in the last 1-3 years, you will need to disclose this.
  2. Before buying any car insurance policy, make sure you know what it covers - price is important, but sufficient cover is essential. Our video explains what a 'good' insurance policy should have and optional add-on features you may want to consider:

What is pushing your estimate up or down:
    Know this This is an estimate to help you sense-check a renewal, not a quote. Insurers price on far more data than we can capture here (your exact address, car make and model, kilometres driven and more), so your real price can sit outside this range.
    Our view The only way to know your actual cost is to compare. Getting two or three quotes is free and often the fastest way to cut what you pay. Start with our top three insurers - Cove, AA Insurance and Tower. To compare the market more widely, see our car insurance comparison guide. If your car is worth under $2,000, it is also worth weighing up third party cover as a cheaper alternative.

    • This calculator is for experimentation and general guidance only. It is built to give you a feel for what comprehensive car insurance might cost, not to tell you what you will actually pay. The figures it produces are estimates based on broad assumptions, and they are not a quote, an offer of insurance, or a guarantee of the price any insurer will charge you.
    • The estimate cannot account for the factors that most influence your real premium. These include the make, model and age of your car and its theft and repair risk, your exact address, how far you drive each year, your full driving and claims history, the specific policy and add-ons you choose, your excess, and any multi-policy or loyalty discounts. Because of this, your actual premium could be materially higher or lower than the range shown here.

Before taking out any policy, read the relevant policy wording so you understand what is and is not covered.
    • MoneyHub may receive a commission if you take out a policy with some of the insurers we link to. This never affects the estimates this calculator produces, the order in which results appear, or our editorial views. You can read more in our advertising and editorial policies.
    ​Compare Car Insurance Quotes With Our Top Three Insurers – Cove, AA Insurance and Tower
    Our comprehensive car insurance research has identified Cove Insurance, AA Insurance and Tower Insurance as leading options based on price and policy cover. 

    Important:
    • Cove Insurance was cheapest in 5 of 7 models where savings were significant and has become very popular with MoneyHub readers. Cove saves you with a free month of cover (up to $100), plus up to 10% off for multiple cars and up to 10% off for annual payments. 
    • AA Insurance, one of New Zealand's most trusted motoring names, backs every repair with a Lifetime Repair Guarantee for as long as you own the car, covers key theft excess-free, and prices consistently in the competitive middle of the market - a major insurer's claims reputation without the big-brand premium.
    • Tower Insurance offers the most comprehensive policy of the insurers we compared, with the widest range of benefits, always excess-free key replacement whether your keys are lost or stolen, and optional breakdown cover that typically costs less than a standalone AA Membership.

    Comprehensive vs Third Party Cover

    By comparing quotes, you can see what cover is right for you. For example, if your car is valued below $2,000 and you have sufficient savings and are looking to upgrade, a third party policy could be a cost-effective option. Our guide to third party car insurance helps compare options.
