Buy a car privately and you can inherit something the seller never mentioned: their lender’s claim over it. The PPSR check is how you find out before your money moves, and it costs about the price of a coffee.
What the register is
The Personal Property Securities Register is a government register recording security interests over personal property in NZ, including vehicles. When someone finances a car, the lender typically registers a security interest against it. That registration follows the car, not the person: if you buy a car with a live security on it, the lender’s claim can survive the sale, and in the worst case the car gets repossessed from you, the innocent buyer, because the previous owner stopped paying their loan.
Read that again, because it is the whole reason this guide exists: you can lose a car you paid for in full, over a debt that was never yours.
How to run the check
You need the car’s details, ideally the VIN, or the registration plate. On the PPSR website you can run a motor vehicle search for a small fee, a few dollars, and get back any registered security interests, usually within minutes. Many buyers use a paid car-history service instead (which bundles the PPSR result with odometer and stolen-vehicle checks); either way, the security search is the part that protects your money.
What you want to see: no registered security interests. What needs action: any live registration, usually naming a finance company.
A dirty result is not always a dead deal
A live security usually just means the seller still owes money on their car loan, which is common and fixable: the loan gets repaid as part of settlement, the security is discharged, and then you pay. The rule is sequence. The security comes off, or the lender in question is the one being paid directly at settlement, before your money moves. What you never do is hand over cash on a promise that the seller will “sort the loan out after”.
Where finance makes this easier, not harder
When a private sale is financed through a lender, the checks stop being your homework. On every private sale BorrowClub is involved in, the PPSR check runs before any money moves, and settlement goes lender to seller, with any existing security repaid and discharged as part of it. The buyer gets the car, the seller gets cleared funds, and nobody is relying on trust. That process is laid out on our private sale car finance page.
One last pairing: the PPSR check protects you from the debt risks, not the mechanical ones. A pre-purchase inspection covers the other half. Do both; together they cost less than one bad week of owning the wrong car.
