Buying a car privately, from a Trade Me listing, a Facebook Marketplace seller or a friend of a friend, can be a great way to find a good car at a fair price. The catch is that private sales in New Zealand are very much buyer beware. Unlike buying from a registered dealer, you do not get the safety net of the Consumer Guarantees Act or the Fair Trading Act, so most of the responsibility for checking the car sits with you. The good news is that a handful of cheap, simple checks will protect you from the most expensive surprises, such as a car that still has money owing on it, a tampered odometer, or a seller who does not actually own the vehicle. This guide walks you through what to check, in what order, and how to complete the sale safely, including how finance can still work when you buy from a private seller.

Private sale vs dealer: why your rights are different
The single most important thing to understand before you buy privately is how few legal protections you have compared with buying from a registered motor vehicle trader.
When you buy from a business, the Consumer Guarantees Act (CGA) requires the car to be of acceptable quality, and the Fair Trading Act stops the seller misleading you. Dealers also have to display a Consumer Information Notice (CIN) on the windscreen and meet the rules of the Motor Vehicle Sales Act.
When you buy from a genuine private seller, none of that applies. The Consumer Guarantees Act, the Fair Trading Act and the Motor Vehicle Sales Act do not cover private sales. In plain terms, the car is sold as is, where is, and if it breaks down the day after you drive it home, that is generally your problem.
That does not leave you completely without rights. Under general contract law (the Contract and Commercial Law Act 2017), you may have a claim if the seller actively lied to you, for example by telling you the car had never been in a crash when it had, or by selling a car they did not legally own. Disputes like these can be taken to the Disputes Tribunal, but recovering money after the fact is slow and uncertain. Prevention is far cheaper than a remedy.
Watch out for traders posing as private sellers. Some dealers list cars as private sales to dodge their responsibilities and offload problem vehicles. In New Zealand, a person who sells more than six vehicles, or imports more than three, in a 12 month period generally has to be a registered motor vehicle trader. If you suspect the private seller is really a trader, search their name on the Motor Vehicle Traders Register and watch for multiple current listings under the same phone number.
Do a PPSR check: the money-owing trap
This is the check people most often skip, and it is the one that can cost you the entire price of the car.
If the seller still owes money on the vehicle (for example, they bought it on finance and have not paid it off), the lender holds a security interest over the car. If the seller stops paying, the finance company can repossess the car from you, even though you paid for it in good faith and had nothing to do with the original loan. You can lose both the car and your money.
You avoid this by checking the Personal Property Securities Register (PPSR) before you hand over any money. The PPSR is the official government register that records security interests against vehicles. A search is cheap (around a couple of dollars) and takes a few minutes at ppsr.govt.nz. You search using the car's plate number or VIN.
A clear PPSR result tells you no lender has a registered interest in the car. If the search shows a security interest, do not buy until it is resolved. The safest approach is to confirm exactly who is owed and how much, and to pay that lender directly so the debt is cleared as part of the sale, rather than trusting the seller to pay it off afterwards.
A PPSR search confirms whether money is owing, but it does not tell you whether the car is stolen or mechanically sound. Treat it as one layer of protection, not the only one.
Check the car is not stolen and the history stacks up
Alongside the PPSR check, run two more background checks before you fall in love with the car.
Stolen check: confirm the vehicle is not recorded as stolen. You can check the car's status using the registration plate or VIN. Buying a stolen car means you do not get legal ownership, and the police can take it back from you.
Vehicle history report: a paid vehicle information report pulls together details a single ad will never show you, including previous owners, recorded odometer readings over time, whether the car was imported and any reported damage. These reports charge a small fee, and they are well worth it.
Odometer tampering, sometimes called clocking, is illegal but it still happens, and it is one of the easiest ways to be overcharged for a worn-out car. A history report flags odometer readings that go backwards or do not add up over time. Back this up with your own eyes: if the ad says low kilometres but the pedals are badly worn, the driver's seat is sagging and the steering wheel is shiny, be suspicious.
Finally, do not treat a current Warrant of Fitness as proof the car is reliable. A WoF is a basic safety check at a point in time, not a guarantee of mechanical condition.
Get a pre-purchase inspection
Because the Consumer Guarantees Act does not protect private buyers, an independent inspection is the closest thing you have to a quality safety net. It is the best money you can spend before buying.
A pre-purchase inspection is carried out by a qualified mechanic or a dedicated inspection service. They check the engine, transmission, brakes, suspension, tyres, electronics and underbody, and look for signs of crash repair, rust or leaks that a quick test drive will never reveal. You can use a mobile service that comes to the car, or book the vehicle into a workshop or an inspection centre.
For electric vehicles, hybrids or unusual imports, use a mechanic who knows that specific type of car. An EV battery health check, for example, can be the difference between a great buy and an expensive mistake.
Do your own basic checks too. View the car in daylight and when it is dry, start it from cold, and take a proper test drive on the kinds of roads you actually use, including a motorway if you can. Listen for noises, check that the car tracks straight, test the brakes, and make sure every warning light goes out after start-up. If the seller refuses a test drive or an inspection, walk away.
Verify the seller and the paperwork match
One of the simplest frauds in a private sale is selling a car the person does not actually own, or is not entitled to sell. A few minutes of checking prevents it.
Ask for photo ID (a driver licence is ideal) and confirm the seller's name and address match the person recorded as the registered owner of the vehicle. Be cautious if you are asked to deal with someone selling on behalf of the owner, or if the registered name is different from the person in front of you with no clear explanation.
Check the car's documents in person. The registration (rego) should be current, or you should factor in the cost of bringing it up to date, because once you own the car you are liable for licensing fees from the purchase date. If the vehicle uses Road User Charges (most diesels and some EVs), confirm there is no outstanding RUC debt, as that debt follows the vehicle, not the previous owner.
Always view the car at the seller's home or workplace, not a random car park. It confirms the seller is who they say they are and gives you a real address if something goes wrong later. Match the number plate and VIN to the documents and the history report.
Negotiate and pay safely
Once the checks stack up, you can negotiate from a position of strength. Anything the inspection or history report turned up, worn tyres, an upcoming cambelt, a slightly high odometer for the year, is a fair reason to ask for a lower price. Decide your walk-away number before you start and stick to it.
Put the agreement in writing. A simple sale agreement protects both sides and is your evidence if there is a later dispute. Include the full names and addresses of buyer and seller, the vehicle details (make, model, plate, VIN and odometer reading on the day), the agreed price, the payment method, the WoF and registration status, and a statement that no one else has a claim on the car. Both parties sign and date it, and you each keep a copy.
Pay in a traceable way. A bank transfer that clears before you take the car is safest, because it leaves a record and there is no large amount of cash changing hands. Be wary of any seller pushing for cash only or pressuring you to pay a deposit to hold a car you have not seen.
Sort insurance before you drive away. Arrange cover to start from the moment you take possession, not the next day. You can usually set this up in advance, and if the sale falls through you simply cancel it.
Complete the change of ownership with Waka Kotahi (NZTA)
The sale is not finished when the money moves. Ownership has to be transferred with NZTA Waka Kotahi, and both the buyer and the seller have a part to play.
As the buyer, you notify NZTA that you have bought the vehicle. If you have a New Zealand driver licence, the easiest way is online through NZTA's online services at the time of sale. If you are buying through a company, or you do not have a NZ driver licence, you complete the buyer's form (an MR13B) at an NZTA agent such as VTNZ or an AA centre.
The seller separately notifies NZTA that they have sold the car. This is important for them, because until they do, they can remain liable for things like parking and speed camera tickets on a car they no longer own. A sensible handover is for the seller to wait until you have shown proof you have notified NZTA before they hand over the keys.
Once the change of ownership is processed, NZTA sends a new certificate of registration to you as the new owner. Keep it with your sale agreement and the receipt. Make sure the WoF is no more than one month old at the time of handover.
Your private-purchase checklist
Use this as a quick run sheet. If you can tick every item, you have done the work that protects you in a private sale.
Before you view: know your budget and the model you want. Get any car finance sorted in principle so you can move quickly. Search the seller and the listing for signs of a trader posing as a private seller.
Before you pay: run a PPSR check at ppsr.govt.nz to confirm no money is owing. Run a stolen-vehicle check using the plate or VIN. Buy a vehicle history report and review the odometer trail. Book and complete an independent pre-purchase inspection. Confirm the seller's ID and address match the registered owner. Check the rego, WoF and any Road User Charges are current or priced into your offer.
At the sale: negotiate using what the checks revealed. Sign a written sale agreement with all the key details. Pay by traceable bank transfer, never under pressure. Arrange insurance to start the moment you take the car.
After the sale: notify NZTA Waka Kotahi that you have bought the vehicle, and confirm the seller has notified them of the sale. File your agreement, receipt and new certificate of registration.
Can you get finance for a private car purchase?
Yes. A common myth is that car finance is only available when you buy from a dealer. You can absolutely arrange finance to buy a car from a private seller, which means you do not have to drain your savings to grab a good car when you find one.
Because lenders may have a security interest in a car they finance, doing your PPSR check and a tidy change of ownership matters even more when finance is involved, both yours and any the previous owner had. A good broker helps you line up the funds so you can complete the purchase cleanly and pay the seller in one traceable transfer.
