Backpacker's Guide - Buying and Selling a Car in New Zealand: The Paperwork

The paperwork is the part of buying and selling a car that backpackers worry about most, and it's also the part that goes wrong most often. The good news is that in New Zealand the process is online, quick, and free. The catch is that it only works if both sides do it, and it has to be done straight away.

If you haven't bought yet, start with our 15-minute inspection checklist. This guide picks up once you've found the car.

How Change of Ownership Works

When a vehicle changes hands, New Zealand keeps a record of the registered person on the Motor Vehicle Register. Both people have a job to do:

• The seller tells NZ Transport Agency (NZTA) the vehicle has been sold. This is called a notice of disposal (form MR13A).
• The buyer tells NZTA they now own it. This is called a notice of acquisition (form MR13B).

NZTA says you are legally required to do this immediately, that it's free online, and that both people need to complete their part for the change of registered person to finish. Do it together at the time of sale.

If You're Buying

1. Check who is selling. The seller should be the registered person. Check the ID matches before you pay.
2. Check for money owing and the car's history before you hand over cash. The inspection checklist covers how.
3. Get a written receipt. Both of you should sign it. Include the date and time, both names and contact details, the plate, the VIN or chassis number, the odometer reading and the price.
4. File your notice of acquisition straight away on NZTA's online transaction site, with the seller beside you if possible.
5. Check the registration and WOF are current before you drive away, and arrange insurance from day one.
6. If it's a diesel, check the RUC. See our RUC guide.

If You're Selling

This is where most of the trouble happens. Until the change of ownership is completed, you can still be the registered person on record, which is why fines and notices can end up with you long after the car has gone.

• Lodge your notice of disposal immediately, ideally on your phone while the buyer is standing there. Don't leave it for later.
• Keep the buyer's details and records. Sellers who've been chased for someone else's fines say the same thing: keep a signed receipt, the buyer's name and phone number, and screenshots of your notice. It is your proof of when and to whom the car was sold.
• Don't delay. Sellers describe fines, and even questions from police, arriving months after they sold a car because the paperwork was left undone.
• Leave the plates on the car. Number plates stay with the vehicle unless it is being scrapped.
• Tell your insurer once the sale is done, and cancel your cover from that date.

Selling Before You Fly Home

• Start early. As we said in the budget car guide, list the car two to four weeks before you leave.
• Give the car a wash, gather your service receipts, and be clear on the WOF and registration expiry dates in your listing.
• Do the change of ownership online at handover. Don't accept 'I'll do it tomorrow' from a buyer.
• If a sale falls through close to your flight, a buy-back option removes a lot of stress. It's worth asking about when you buy.

If the Buyer Doesn't Do Their Part

Keep every record and contact NZTA. Don't wait for the fines to pile up. The receipt, the messages and your notice of disposal are what protect you.
