My car has aftermarket wheels and a different stereo. Are those covered if they're stolen or damaged?
Yes, your aftermarket wheels and different stereo may be covered by your car insurance in New Zealand if they're stolen or damaged. However, it depends on your insurer, your type of cover, and whether you've declared the modifications when required.
The important thing to know is that covering your car doesn't automatically guarantee that every aftermarket part will be fully covered.
1. Are your aftermarket wheels and stereo covered?
Here's how cover generally works in New Zealand.
| Situation | Are your wheels and stereo covered? |
|---|---|
| Your car is stolen with the wheels and stereo fitted | Potentially, depending on your policy and the agreed cover. |
| Someone steals your wheels while your car is parked | Potentially, if your policy covers theft of accessories or parts. |
| Someone breaks into your car and steals the stereo | Potentially, subject to your policy's theft provisions. |
| Your wheels are damaged in an accident | Potentially, particularly under comprehensive insurance. |
| Your stereo is damaged in an accident | Potentially, subject to your policy's terms. |
| You have third-party-only insurance | Generally, your own wheels and stereo won't be covered for theft or accidental damage. |
For example, AA Insurance's policy wording specifically includes aftermarket wheels and fitted entertainment systems in its definition of vehicle accessories. However, the applicable policy terms determine whether a particular claim is covered. AA Insurance
2. Do you need to tell your insurer about the modifications?
Yes, it's best to tell your insurer about both the wheels and the stereo.
Insurers differ in how they treat aftermarket parts.
- Some insurers: Require you to declare all modifications, including aftermarket wheels and stereo equipment.
- Other insurers: Only require you to declare specific modifications listed in your policy.
- Some policies: Cover accessories automatically, but you may need to include their value in your vehicle's insured value.
For example, AMI advises customers to disclose modifications such as alloy wheels and aftermarket stereo equipment. Other insurers, including BNZ's car insurance provider, distinguish between modifications that must be declared and accessories that do not require separate notification. AMI Site
If you've already installed these items, contact your insurer and ask them to confirm your cover in writing.
3. Will the insurer pay the full replacement cost?
Not necessarily.
The amount you receive may depend on:
- Your sum insured: Does the insured value of your car account for the additional value of the wheels and stereo?
- Your policy's terms: Does it cover aftermarket accessories, and are any limits applicable?
- Your excess: You may need to pay an excess when making a claim.
- Replacement arrangements: Your insurer might offer an equivalent replacement rather than the exact brand or model you originally purchased.
New Zealand's Consumer Protection guidance recommends checking your policy to understand what is covered and how the insurer calculates a claim payment. Consumer Protection
It's worth keeping receipts, installation invoices and photographs of your wheels and stereo to help establish their value if you need to claim.
4. Let's check what applies to your car
I can help you narrow this down based on your actual insurance arrangements.
Which insurance company are you with, and what type of cover do you have?
For example, you might have AMI comprehensive, AA comprehensive, State comprehensive, or third-party fire and theft.
If you tell me your insurer and cover type, I can look into its specific rules for aftermarket wheels and stereos, including whether you need to declare them and what happens if they're stolen or damaged.
