What Happens If You Let Someone Else Drive Your Car?

Introduction

Letting a friend, partner or family member drive your car does not have a simple yes-or-no insurance answer. In our editorial review, the key questions are whether you gave permission, what your policy schedule says, the cover you bought, driver restrictions, licence compliance and the vehicle’s permitted use.

Permission can be important, but it does not override a named-driver requirement, age-related term, licence condition, exclusion or other policy condition. Before lending your vehicle, compare the schedule with the policy wording—not assumptions. You can also use our car insurance comparison information to help frame the policy features worth checking.

Quick guide: what to check before handing over the keys

When another person may be covered

Some policies can extend legal-liability cover to a person using the insured vehicle with the policyholder’s permission, subject to the policy’s terms and provided the liability is not covered by other insurance. That does not mean every loss is covered.

If a claim falls within the cover purchased and all applicable terms are met, an insurer may cover damage to the insured vehicle, the borrower’s legal liability, or both, depending on the cover level and wording. Third-party-only cover does not ordinarily insure accidental damage to the policyholder’s own car after an at-fault crash.

Named drivers, young drivers and regular use

Do not assume that an occasional borrower is acceptable under every policy. Consumer Protection NZ says that where a policy names drivers, an insurer is unlikely to honour a claim if someone else drives and has an accident.

Drivers under 25 may have special terms, higher risk pricing, an additional excess or an exclusion, depending on the insurer and policy schedule. Under-25 restrictions can exist, but they are not universal. Likewise, excess structures are product- and schedule-specific; do not assume an unnamed or inexperienced borrower will always trigger an additional excess.

Regular use needs particular care. ICNZ advises consumers to disclose main and additional drivers and update insurers when relevant information changes. Consumer Protection NZ also warns that listing a parent as the main driver when their child mostly drives the vehicle may leave the vehicle without cover after an accident.

Licence compliance matters

The borrower must be legally allowed to drive in New Zealand, hold a licence appropriate to the vehicle class and comply with their licence conditions. Insurers may decline cover where a licence breach contributed to an accident. For example, Consumer Protection NZ notes that a claim may be declined when a restricted-licence driver carries passengers contrary to their restrictions or drives after 10pm, or when a vehicle is driven outside the driver’s licence class.

Restricted-licence conditions include passenger restrictions unless the driver is accompanied by an eligible supervisor. For a borrower using an overseas car licence, the position is time-sensitive: as at 17 August 2026, NZTA says an eligible person can generally drive for up to 18 months from their last entry into New Zealand. This period reduces to 12 months on 1 November 2026. Check NZTA guidance and the insurer’s wording where an overseas licence is involved.

Do not lend your car to someone who is not legally allowed to drive or who will drive while impaired. Alcohol use and licence-condition breaches can result in a declined claim under applicable policy exclusions and terms.

If there is an accident

1. Check safety and legal obligations first. Then record the relevant details and notify the insurer in line with the policy’s claims process.
2. Do not presume the outcome. The insurer will assess permission, the policy schedule, cover level, driver eligibility, licence compliance, use of the vehicle and the facts of the incident.
3. Check the applicable excess. For an accepted claim, the vehicle excess and any other applicable excess generally apply unless the policy says otherwise. The schedule and wording determine what applies and how the claim is settled.
4. Ask about future policy effects. A claim can affect future terms or price, but any effect on renewal pricing or a no-claims benefit is insurer- and policy-specific.

If you disagree with a declined claim, first raise the issue with the insurer’s complaints team. If it remains unresolved, Consumer Protection NZ advises asking which dispute-resolution service the insurer belongs to.

What to Do Next

• Read the current policy schedule as well as the full wording before lending the car.
• Confirm the borrower has permission, the required licence and no relevant restriction that would be breached on the intended trip.
• Check named-driver terms, age-related terms, permitted use and every potentially applicable excess.
• If the person will drive regularly or become the main driver, notify the insurer promptly and ensure the policy information is accurate.
• Notify the insurer as soon as possible of a change that could affect the chance or amount of a claim, or information recorded in the schedule. The insurer may change the terms or cancel the policy.

This is general information, not personalised insurance advice. Your own schedule and policy wording control, so ask your insurer to confirm how its terms apply before someone else drives your car.
