# S-P04-M-03: What should I check if my flatmate sometimes drives my insured car? Collected 11 October 2026 [Car insurance study](https://nzbrands.ai/research/insurance/car-insurance) ## ChatGPT Answer ID: 74c53d64-3f00-4140-bfb8-c5600e757935 If your flatmate sometimes drives your insured car in New Zealand, the main thing to check is whether your car insurance covers them as an occasional driver, and whether any extra excess or restrictions apply if they have an accident. You don't necessarily need a separate policy just because your flatmate drives your car, but you shouldn't assume they're covered simply because you are insured. ## What to check - 1. Who is allowed to drive? Check whether your policy covers any licensed driver who has your permission, or only named drivers. Your flatmate may need to be added to the policy. - 2. Occasional versus regular use. Check whether your insurer treats your flatmate as an occasional borrower or a regular driver. If they drive your car every week, for example, tell the insurer rather than assuming they're an occasional driver. - 3. Additional excess. Some policies charge an extra excess when someone other than the policyholder, or a driver under a certain age, has an accident. - 4. Driver restrictions. Check age limits, licence requirements, learner or restricted licence conditions, and exclusions relating to driving history. - 5. What your policy covers. Third-party cover, third-party fire and theft, and comprehensive cover protect against different types of loss. Check whether damage to your own car and damage to other people's property are covered when your flatmate is driving. - 6. Who pays if there's an accident? Your insurer will generally deal with a claim under your policy if the circumstances are covered, but an excess may apply and a claim could affect your no-claims discount or future premiums. Agree with your flatmate in advance on how you'll handle any excess or costs not covered by insurance. - 7. Other conditions. Check exclusions for unauthorised use, driving under the influence, business use, or other restricted activities. ## What to ask your insurer You can send them this message: Writing Hi, I’d like to check my car insurance cover. My flatmate sometimes drives my car with my permission. Are they covered under my current policy, or do I need to add them as a named driver? Could you also confirm whether an additional excess applies if they have an accident, and whether their age, licence type or driving history affects the cover? Please let me know if I need to update any details on my policy. It's worth getting confirmation in writing. New Zealand's Consumer Protection guidance says that allowing an unnamed driver to use your car can be a problem if your policy restricts who may drive it.

I can help you check the specific rules for your policy. ## Gemini Answer ID: 743c6bc6-f1bb-4b8d-abce-f97cb799b8df If your flatmate occasionally drives your insured car in New Zealand, you need to review your insurance policy details carefully to avoid a nasty surprise at claim time. The key things to check on your policy include: * **Driver Restrictions ("Named" vs. "Open" Drivers):** Check your policy schedule to see if it specifies who is allowed to drive. Some policies are restricted to "named drivers only" (meaning only specific people listed on the policy are covered), while others have an "open driver" policy (allowing anyone with a legal license and your permission to drive). If your policy is restricted and your flatmate isn't listed, they won't be covered. * **Frequency of Use:** Even if your policy allows other drivers, check how your insurer defines a "regular driver." Many New Zealand insurers require anyone who drives your car more than a certain frequency (e.g., once a month, or regular commuting use) to be explicitly listed on the policy. * **Age and Licence Excesses:** Check if your policy has special excess penalties for younger drivers or drivers on a restricted/learner licence. If your flatmate is under 25 or doesn't hold a full New Zealand driver's licence, an additional "inexperienced driver excess" could apply on top of your standard excess if they have an accident. * **Impact on No-Claims Bonus (NCB):** Clarify how a claim involving your flatmate would affect your insurance record. If they have an at-fault accident while driving your vehicle, the claim sits on your policy history, which can spike your future premiums and impact your no-claims discount (unless protected). **Next Step:** It is usually quick, easy, and sometimes free or low-cost to simply call your insurance provider or log into your online portal to add your flatmate as a named driver. Would you like to know what specific questions to ask your insurer when you call them? ## AI Overviews Answer ID: f6e4fd20-8144-4a09-a069-991f0533a233 If your flatmate sometimes drives your car in New Zealand, you need to check several important details regarding your insurance policy, their licence, and potential extra costs. 1\. Your Insurance Policy Type and Driver Rules * **Named vs. Open Driver:** Check whether your policy is an **open-driver** policy (which covers any licensed driver with your permission) or a **named-driver-only** policy. If it is named-driver only, an unlisted flatmate may not be covered at all. * **Mandatory Disclosures:** Most New Zealand insurers (such as AA Insurance or [State Insurance](https://www.state.co.nz)) require you to specifically name any driver who is under 25, is on a learner/restricted/overseas licence, or has a poor driving/conviction history. * **Under-25 Exclusions:** Some policies (like certain [AMI Insurance](https://www.ami.co.nz) plans) automatically exclude drivers under 25 unless you explicitly add them and pay an extra premium or specific young-driver cover. 2\. Excesses and Extra Costs * **Unlisted Driver Excess:** If your flatmate is not listed and has an accident, your insurer may apply an extra **unlisted driver excess** on top of your standard excess. * **Age or Licence Excess:** If your flatmate is under 25 or on a restricted licence, a young-driver or inexperienced-driver excess will usually apply. * **Claims History Impact:** Remember that in New Zealand, motor insurance is tied to the **vehicle**. If your flatmate crashes your car, the claim goes against _your_ policy, which can raise your future premiums or affect your no-claims bonus. 3\. Your Flatmate's Licence and Status * **Valid Licence:** Confirm they hold a current, valid New Zealand driver's licence (or a valid overseas licence within legal timeframes) appropriate for the vehicle. * **Licence Conditions:** Ensure they follow any conditions attached to their licence, such as passenger or time-of-day restrictions on a restricted licence, because breaking licence conditions can invalidate insurance cover. If you'd like, tell me: * **Which insurance company** you are with * **How old** your flatmate is and **what kind of licence** they hold I can help you check what specific rules or extra costs might apply. ## Google AI Mode Answer ID: 79674de8-58fe-47fa-9fa4-f578a7e7345d If your flatmate sometimes drives your car, you **must check your car insurance policy wording regarding open-driver clauses, unlisted or unnamed driver excesses, and age/licence restrictions**. Insurance rules in New Zealand vary widely between providers, meaning an unannounced driver can result in a significantly higher bill if an accident occurs. [Quashed] Key Policy Details to Check * * **Open Driver vs. Named Driver Policy:** Check whether your policy is an Open Driver or Named Driver policy. If it is a named-driver-only policy, anyone else driving the car may not be covered at all unless added. If it is an open-driver policy, occasional drivers are generally permitted. * **Unlisted/Unnamed Driver Excess:** Review your fine print for an additional excess fee that triggers if an unlisted person is driving during a claim. This can add hundreds or thousands of dollars on top of your standard excess. * **Age Restrictions and Young Driver Excess:** Check if your policy has a blanket minimum age exclusion (such as no cover for drivers under 25) or applies a steep additional young driver excess if your flatmate is under 25. * **Licence Status Requirements:** Ensure your policy specifies what kind of driver's licence your flatmate must hold. Some policies require a full New Zealand driver's licence or an approved international licence [6.4], and may restrict or invalidate cover if they drive on a learner or restricted licence without meeting specific conditions. * **Frequency of Use:** Check how your insurer defines "occasional" versus "regular" use. If your flatmate drives the car routinely or uses it as their primary vehicle, they may need to be officially listed on the policy to avoid complications or a denied claim for misrepresentation. * If you'd like, let me know: * Your **insurer's name** * Your flatmate's **approximate age** and **licence type** (full, restricted, learner, or overseas) I can help outline what specific questions you should ask your provider.
