Your insurance premium

Many factors can impact the amount of premium that we charge, including what you’re insuring, the policy you choose, and how we calculate premiums from time to time. We understand that premiums, and changes to them, can be confusing so we’ve put together some of the factors that can influence the premiums you pay.

What impacts home and/or contents insurance premiums?

When insuring your home and/or contents, we ask several questions to help you determine the cover you need and the associated premium. Some of the key pieces of information that impact your premium are listed below.

Location

Some places in New Zealand are considered riskier than others. As more data about New Zealand’s landscape and the likelihood of weather-related or natural hazard events becomes available, we’re adapting and updating the way we price our policies by using third-party data to help estimate the probability and impact of natural hazard events. This means that customers in areas at higher risk of weather events and natural hazards could pay higher premiums, and vice versa. In general, coastal towns and cities are more at risk from storm inundation and tsunami, whereas other areas might be more at risk of landslide, flood, earthquakes, or volcanic activity.

Certain areas with higher reported instances of theft and/or vandalism can also have an impact on premiums.

Cover type (contents)

The type of policy you choose directly impacts your level of cover in a claim and therefore your premium. For example, our Limited Contents Insurance protects your contents against burglary, fire, storm, flood or natural disaster but doesn’t cover accidental damage and loss, whereas our Contents Insurance is our most comprehensive cover and covers your contents if they’re lost or damaged by a sudden, unforeseen and accidental event.

Paying by instalments

We've observed a link between payment frequency and the likelihood of making a claim. As a result, payment frequency is one of the rating factors used to determine your premium. This means your payment choice affects your premium, and you'll pay less if you choose to pay annually.

Customising your policy

Updating your policy to suit your needs can impact your premium. For example, increasing adjustable event limits (contents and limited contents insurance) and/or adding on optional benefits increases your cover and therefore increases your premium.

Sum insured

The sum insured is the most you can claim for any one event unless otherwise stated in your relevant policy document. It’s important to keep it up-to-date and ensure it will sufficiently cover the rebuild of your home and/or replacement of your contents.

Building materials (home)

The materials used to build a home will affect the premium charged, in particular, the roof and wall materials as these are what protects a home and your contents from outside elements.

Year of construction (home)

The year your property was built could influence your premium. For example, certain types of construction methods and materials have been shown to impact the likelihood of a claim occurring.

Excess

Your excess is the amount you pay when you make a claim. There are different excess options available, in case you need to make a claim. Generally, the higher the excess, the lower the premium and vice versa.

Alarm (contents)

If you’ve told us whether you have an alarm installed at your home, this will be used as a rating factor when calculating your premium and will be noted on your policy schedule.

What impacts car insurance premiums?

When insuring your car, we ask several questions to help you select the cover you need and the associated premium. Some of the key pieces of information that impact your premium are listed below.

Cover type

The type of policy you choose directly impacts your level of cover in a claim and therefore impacts your premium. For example, Comprehensive Car Insurance covers damage to your car, as well as damage you might cause to someone else's car or property so is more expensive than Third Party Car Insurance which only covers damage you might cause to someone else's car or property.

Type of car and how you use it

The type of car you own can have a significant impact on your premium, because the cost and availability of replacement parts can vary based on a vehicle’s make, model and age. In addition, if you use your car for business use, your premium may be higher because of the increased amount of driving compared to typical private usage.

Paying by instalments

We've observed a link between payment frequency and the likelihood of making a claim. As a result, payment frequency is one of the rating factors used to determine your premium. This means your payment choice affects your premium, and you'll pay less if you choose to pay annually.

Location

Areas with higher reported incidences of theft and vandalism could see higher premiums, and more populated areas mean more traffic and an increased likelihood of damage occurring. This is monitored by analysing our claims data.

Drivers

A driver’s age and experience can affect their likelihood of having an accident or claim. For example, we generally see more experienced drivers have fewer accidents. This is monitored by analysing our claims data.

Agreed value

The amount your car is insured for affects your premium. Your agreed value will usually be adjusted every year at renewal to account for any changes in line with the market.

Finance

We’ve observed a link between finance owing on vehicles and the likelihood of making a claim. As a result, finance owing on your car is a rating factor which impacts your premium.

Excess

Your excess is the amount you pay when you make a claim. There are different excess options available, in case you need to make a claim. Generally, the higher the excess, the lower the premium and vice versa.

What influences AA Insurance premiums?

The amount of premium we charge customers can be influenced by several factors, some of which are external to what you’re insuring. This means that each year your premium can change, even if your personal circumstances haven’t.

Claims

A premium may change if we receive more claims than planned for or these cost more than expected (for example, the cost of materials or parts increases). We also try to anticipate our future claims costs based on data from our past claims experience. In addition, we use third party data to try to predict what claims may cost us for certain types of damage e.g. severe weather events such as storms and floods.

Pricing

Premiums can be impacted by changes in our pricing practice, rating factors and how we calculate premium from time to time. For example, depending on where you’re based in New Zealand, the premium you pay can be influenced by a range of factors, including your location and the likelihood of a weather-related or natural hazard claim which may include storm, flood or earthquake.

Reinsurance

Part of the premium we collect from our customers goes towards paying our own insurance premium to reinsurance providers. This is additional cover we purchase to protect us against exposure to large scale events such as storms, floods and earthquakes. This helps us maintain our ability to pay claims. As the cost of our reinsurance changes, so too could your insurance premium.

Expenses and profit

Like any business, we have expenses and operating costs that enable us to service our customers. We invest in the technology and products that we believe will enhance our customer experience. We also need to make a profit to ensure we can continue running our business year after year, and this can vary significantly depending on large scale events.

Taxes and levies

Any applicable taxes and levies are applied including GST, Natural Hazards Insurance and Fire and Emergency levies, which we collect on behalf of the government. From 1 July 2024, the Fire and Emergency levy increased. Please visit our levies page for more information.

Concerned about the cost of your insurance?

Here are some ways to save on your premium.

Check your contents sum insured – use the online calculator on our website (provided by ‘Sum Insured Pty Ltd’) to check everything is up-to-date and that the cover you have would be enough to replace all your contents if you lost everything. For example, if you have downsized since setting up your policy, you may be paying for more cover than necessary. It’s also important your sum insured is updated when you buy new stuff or upgrade your belongings (especially expensive items like a new TV or sofa) so you’re not caught short in the event you need to claim. Often, the extra bit of cover you could need might not significantly increase your premium.

Review your excess – depending on what you think is manageable for your budget, you may want to review your excess. There are different excess options available, in case you need to make a claim, and generally the larger the excess, the smaller the premium. Remember, you’ll need to pay this amount if you make a claim so it should still be affordable. You should also take into account any additional excesses that may apply.

Check your home sum insured – use our online calculator to check it’s up-to-date and will sufficiently cover the rebuild of your home. For more information, check out our sum insured page.  

Consider how you pay – you can choose to pay your premium annually or spread the cost by fortnightly or monthly direct debit. You’ll pay less if you pay one annual lump sum.

Review your benefits – you’ll find your optional benefits listed on your policy schedule or on the Policy Summary page in your My AA Insurance account. For example;

  • If you could use another vehicle while yours is being repaired and wouldn’t need us to provide a rental car, you may wish to remove the optional rental cover benefit from your Comprehensive Car Insurance Policy. Removing this benefit saves $50 (Inc. GST) per year.

  • You may decide you no longer want or need the optional excess-free glass cover benefit for your Home Insurance Policy. Removing this benefit saves $69 (Inc. GST) per year.
