Selling a Car on Trade Me NZ 2026: Insurance for Test Drives, Handovers & Change of Ownership
Selling your car privately on Trade Me is a familiar routine for hundreds of thousands of Kiwis every year. You photograph it, write the listing, field enquiries, and arrange viewings. But somewhere between the first test drive and the moment you hand over the keys, there is a window of risk that most private sellers never think about — and it centres on one question: what happens to your car insurance during the sale process?
Most NZ car insurance policies were designed for the everyday scenario — you driving your own car, or a named family member behind the wheel. They were not designed for a stranger from the internet turning up to take your vehicle for a 30-minute test drive on unfamiliar roads. And yet that is exactly what happens in a private sale.
The insurance gaps are real. Most private sellers don’t know whether their policy covers test drives by strangers, at what point cover transfers to the buyer, or how changing ownership affects their no-claims bonus. A single incident during a test drive — a fender bender, a stolen vehicle, a write-off at a roundabout — could leave you thousands of dollars out of pocket if your policy doesn’t respond.
This guide walks you through exactly what to check before your first viewing, how NZ insurers typically handle test drives and handovers, and how to protect yourself at every stage of the sale.

Step 1. Understand the Insurance Risks of Selling a Car Privately
Why Private Sales Create an Insurance Gap
When you sell through a dealership, insurance during the sale process is their responsibility. Dealers carry comprehensive policies that cover test drives, yard damage, and transit. Private sellers have no such safety net. Your personal car insurance policy is the only thing standing between you and a significant financial loss if something goes wrong during the sale.
The risk window opens the moment a stranger sits in your driver’s seat for a test drive. It stays open through negotiations, the handover period, payment processing, and the change of ownership notification to Waka Kotahi NZ Transport Agency (NZTA). At any point during that window, an incident could occur — and whether your insurance responds depends entirely on your policy wording and the steps you have taken in advance.
Common Incidents During Private Car Sales
The types of claims that arise during private car sales include:
A test driver causing an accident — ranging from a minor car park bump to a serious collision.
The vehicle being stolen during a test drive, particularly where the seller is not in the car.
Damage occurring during the handover period — for example, a buyer who has paid but not yet completed the change of ownership notification.
A buyer driving uninsured after purchase, causing an accident that the seller’s insurer is asked to cover because ownership has not been formally transferred.
Cosmetic damage during viewings — door dings, scratches from leaning on panels, or damage from moving the vehicle for inspection.
Many of these scenarios fall into grey areas where insurers may investigate before paying out. The clearer your preparation, the stronger your position.
Step 2. Check Whether Your Policy Covers Test Drives by Strangers
How Most NZ Insurers Handle Other Drivers
Most comprehensive car insurance policies in New Zealand operate on an “open driver” or “any authorised driver” basis. This means that any licensed driver who has your permission to drive your vehicle is generally covered, provided they meet the policy conditions. For example, AA Insurance’s open driver policy covers any licensed driver with the owner’s permission, provided the driver has no unacceptable driving or criminal convictions and no unacceptable declined claims. State Insurance similarly covers any driver with the owner’s permission, as long as they meet the same terms and conditions as the policyholder.
This is good news for private sellers — it means a test driver is likely covered under your existing policy in most cases. However, there are important caveats:
The test driver must hold a valid, current New Zealand driver licence (or a recognised overseas licence) and must not be driving in breach of any licence conditions.
The test driver must have your explicit permission to drive the vehicle.
Some policies impose additional excesses for drivers under 25 or drivers not named on the policy. If a 19-year-old test drives your car and crashes, you may face a significantly higher excess — several hundred dollars or more on top of your standard excess.
Some policies carry a Restricted Driver’s Warranty endorsement, meaning only named drivers are covered. If your policy has this restriction, no test driver will be covered unless you add them first.
If the test driver has a history of serious driving convictions or previously declined claims, they may be excluded from cover even under an open driver policy.
What About Third Party and TPFT Policies?
If you hold a third party fire and theft (TPFT) policy, a test driver who causes an accident will not be covered for damage to your own vehicle. Your policy would only respond if the vehicle was stolen or damaged by fire. The damage the test driver causes to other vehicles or property may be covered under the third party component — but damage to your car is your problem.
A third party only policy provides no cover at all for your own vehicle. If a test driver writes off your car, you have no claim under your insurance. You would need to pursue the test driver personally for the cost of the damage.
For a full comparison of the three levels of cover, see Quashed’s guide to Comprehensive vs Third Party Car Insurance NZ.
Test Drive Cover at a Glance
Scenario | Comprehensive | TPFT | Third Party Only |
Test driver damages your car | Covered (excess applies) | Not covered | Not covered |
Test driver damages another vehicle | Covered | Covered | Covered |
Car stolen during test drive | Covered | Covered | Not covered |
Test driver under 25 causes accident | Covered (higher excess likely) | Check policy | Not covered |
Restricted Driver Warranty on policy | Not covered unless named | Not covered unless named | Not covered unless named |
Note: Cover varies by insurer. Always check your specific policy wording for exclusions and conditions.
Step 3. Protect Yourself Before and During the Test Drive
Before the Test Drive
Call your insurer and confirm your policy covers other drivers during a private sale test drive. Ask specifically about any restrictions, exclusions, or additional excesses that may apply. This call takes five minutes and could save you thousands.
Ask the test driver for their full driver licence before they get behind the wheel. Check that it is current and valid. Take a photo of the licence with their permission — this gives you a record of who drove the vehicle and when, which is invaluable if you need to make a claim.
Get the test driver’s phone number and confirm their identity matches the licence.
Check that your rego and WoF are current. While an expired WoF will not automatically void a claim, it can trigger additional investigation and delay your payout.
During the Test Drive
Go with them. Riding in the passenger seat is the single most effective way to reduce your risk. You can observe how they drive, you stay with the vehicle at all times, and if an incident occurs you are there to manage it immediately.
If you cannot go with them, hold their car keys as security and set a clear time limit for the drive. Agree on the route in advance.
Take a photo of the vehicle’s condition immediately before the test drive — front, rear, both sides, and any existing damage. This establishes a baseline if the test driver causes new damage.
Never leave the keys in the ignition with a stranger while you are not in the car. Car theft during test drives is uncommon but not unheard of.
Tip: Trade Me’s own seller guidance recommends checking your insurance covers test drivers, requesting proof of identity, agreeing on how long the test drive should take, and keeping the buyer’s phone number. Follow these steps as a minimum.
Step 4. Understand When Your Insurance Cover Ends and the Buyer’s Begins
The Handover Grey Zone
The most dangerous moment in a private car sale — from an insurance perspective — is the handover. This is the period between the buyer paying for the vehicle and the change of ownership being formally registered with Waka Kotahi NZTA. During this window, it is often unclear whose insurance covers the vehicle.
Here is how it typically works:
Your car insurance covers your vehicle while you are the registered owner and the vehicle is in your possession.
Once you hand over the keys and the buyer takes possession, your insurer may consider the vehicle no longer in your custody or control — which could affect whether a claim is accepted.
The buyer’s new insurance policy (if they have one) generally attaches once they take possession and have an insurable interest in the vehicle, but this varies by insurer.
If neither party has notified their insurer, there may be a gap where neither policy clearly responds.
How to Close the Gap
The safest approach is to insist that the change of ownership is completed before or at the same time as you hand over the keys. Both the buyer and seller must notify Waka Kotahi NZTA of the change. The buyer can do this online through the NZTA website immediately, and you should ask to see their confirmation before releasing the vehicle. Under NZ law, both parties must notify NZTA as soon as possible — and within seven days at the latest — to avoid fines.
At the point of handover:
Confirm payment has cleared in full before handing over the keys. For bank transfers, wait until the funds are visible in your account.
Complete the change of ownership online together, on the spot. This is the most reliable way to ensure both parties are protected.
Notify your insurer that you have sold the vehicle. This prevents you from being liable for any incidents after the sale and allows you to cancel or transfer your policy.
Be aware that if the buyer does not have their own car insurance in place before taking possession and causes an accident after the sale, your former policy will not cover them.

Step 5. Know How Selling Your Car Affects Your No-Claims Bonus
What Happens to Your No-Claims Bonus When You Sell
A no-claims bonus (also called a no-claims discount) is a discount on your car insurance premium that rewards claim-free driving. In New Zealand, the bonus typically grows for each year you remain claim-free, up to a maximum of around five years with most insurers. However, it is worth noting that several major NZ insurers — including AA Insurance, Tower, and Trade Me Insurance — have discontinued no-claims bonuses for new customers in recent years. AMI and State have also stopped offering them on new policies.
If you sell your car and purchase a replacement vehicle, your no-claims bonus is generally linked to you as a driver, not to the specific vehicle. This means you can transfer your claims history to a new policy on your replacement car. However, you should be aware of the following:
If you sell your car and do not immediately purchase a replacement, your no-claims bonus may lapse after a period of time (this varies by insurer). Check with your insurer how long your bonus is preserved.
If a test driver causes an accident during the sale process and you lodge a claim, this will count against your claims history — even though you were not the driver. This could result in higher premiums at renewal or the loss of your no-claims bonus.
Your no-claims bonus cannot be transferred to the buyer. It stays with you.
If your insurer no longer offers a no-claims bonus, your claims history still matters. Insurers who have dropped the formal bonus still factor your claim-free years into your premium pricing.
Tip: If you are selling one car and buying another, the transition is a natural moment to compare your car insurance. Premiums vary significantly between insurers for the same driver and vehicle. Don’t assume your existing insurer will offer the best rate on your next car.
Step 6. Compare Your Car Insurance Before and After the Sale
What Kiwis Are Actually Paying for Car Insurance
The average cost of comprehensive car insurance across New Zealand is $1,298 per year ($108 per month) as of Q4 2025, based on Quashed Index data published in February 2026. Auckland drivers pay more, with the regional average sitting at $1,510 per year ($126 per month).
Region | Yearly Cost ($) | Monthly Cost ($) |
National | $1,298 | $108 |
Auckland | $1,510 | $126 |
Wellington | $1,152 | $96 |
Canterbury | $1,215 | $101 |
Source: Quashed Index Q4 2025. Actual costs will vary depending on the insurer, policy coverage, excess levels, and individual risk factors such as age, location, and driving history.
What Comparing Saves Kiwis
Kiwis who don’t shop around for insurance pay an average loyalty tax of $1,351 per year across their car, house, and contents policies combined. The average NZ household paying for all three insurance types now faces a combined annual cost of $4,959 — up 2% from the previous year and 37% higher than three years ago.
When it comes to car insurance specifically, Quashed’s platform data shows that Kiwis who compared their car insurance found a cheaper policy 80% of the time, with average savings of $367 per year.

Final Verdict: Don’t Sell Without Checking Your Cover
Selling a car on Trade Me is straightforward — until something goes wrong. A test drive accident, a stolen vehicle, a buyer who drives away without insurance or without completing the ownership transfer: these are real risks that most private sellers never consider.
The good news is that comprehensive car insurance generally covers test drives under an open driver policy, as long as the test driver holds a valid licence and has your permission. The bad news is that not all policies work this way, and third party and TPFT policies leave significant gaps. The handover period between payment and formal ownership transfer is another window where cover can fall through the cracks.
Before your next Trade Me listing goes live, take five minutes to call your insurer and confirm your test drive cover, check your rego and WoF, photograph your vehicle’s condition, and — if you haven’t compared in the past 12 months — run a free Quashed Market Scan. It takes two minutes, it’s free, and it could save you hundreds. With Quashed, you can find the right level of cover for your situation and sell with confidence knowing you’re properly protected throughout the process.

Frequently Asked Questions: Selling a Car on Trade Me and Insurance
Does my car insurance cover a stranger test driving my car?
Most comprehensive car insurance policies in New Zealand operate on an open driver basis, meaning any licensed driver with your permission is generally covered. However, additional excesses may apply for drivers under 25 or unlisted drivers, and some policies have a Restricted Driver’s Warranty that limits cover to named drivers only. Always check your specific policy wording or call your insurer before allowing a test drive.
What should I do if a test driver crashes my car?
Document everything: take photos of all damage from multiple angles before anything is moved. Get the test driver’s full details (licence, phone number, address). File a police report if the damage is significant or if the driver leaves the scene. Contact your insurer as soon as possible with your policy number, the test driver’s details, photos, and a police report number if applicable. Do not authorise repairs until your insurer has assessed the damage.
At what point does my car insurance stop covering the vehicle when I sell it?
Your car insurance generally covers the vehicle while you are the registered owner and the vehicle is in your possession. Once you hand over the keys and the buyer takes possession, your insurer may no longer consider the vehicle under your custody or control. The safest approach is to complete the change of ownership with Waka Kotahi NZTA at the point of handover, and to notify your insurer that you have sold the vehicle the same day.
Does the buyer need insurance before driving away?
Car insurance is not compulsory in New Zealand, so a buyer is not legally required to have insurance before driving away. However, if they drive without insurance and cause an accident, they are personally liable for all costs. It is worth noting that your insurance will not cover the buyer after the sale is complete and ownership has transferred.
Will a test drive claim affect my no-claims bonus?
Yes. If a test driver causes an accident and you lodge a claim under your policy, this counts against your claims history — even though you were not driving. This could affect your no-claims bonus or lead to higher premiums at renewal. Several major NZ insurers have discontinued formal no-claims bonuses for new customers, but your claim-free history still directly affects your premium pricing.
How much does car insurance cost in New Zealand?
The average cost of comprehensive car insurance in New Zealand is $1,298 per year ($108 per month) as of Q4 2025, based on Quashed Index data. Auckland drivers pay an average of $1,510 per year. Quashed users who compared their car insurance found cheaper cover 80% of the time, with average savings of $367 per year. Run a free Quashed Market Scan to see how your premium compares.
