A vehicle-data result is a point-in-time check, not proof of ownership or mechanical condition. Match the VIN and plate, verify the seller and obtain the checks appropriate to the purchase.
Key points
Used-car checks before you pay
Verify the seller, registration plate, VIN or chassis number and documents before relying on any history report.
Check current licence, WOF or COF, RUC where applicable, reported theft, money owing, odometer and available import or damage history.
A clear database report and valid WOF do not replace a careful test drive and independent mechanical or EV-battery inspection.
NZ used-car pre-purchase checklist
Complete the checks in stages so an early identity or legal-risk problem can stop the purchase before you spend money on later steps.
| Check | What to verify | Warning signs |
|---|---|---|
| Seller and documents | Identity, registered-person match, authority to sell, receipt and sale terms | Urgency, inconsistent names, refusal to meet safely or missing documents |
| Vehicle identity | Plate, VIN/chassis, make, model, year and colour all agree | Altered identifiers, mismatches, fresh plates without explanation |
| Road status | Licence, WOF/COF and RUC information is current and plausible | Expired records, missing history or RUC distance behind the odometer |
| History and finance | Stolen, PPSR, odometer, deregistration, import and available damage information | Security interests, inconsistent readings or unexplained history gaps |
| Physical condition | Cold start, road test and independent inspection appropriate to the vehicle | Warning lights, leaks, smoke, noises, uneven wear or inspection refusal |
Start by checking the seller
Ask for the seller’s full name and evidence that connects them with the transaction. Use NZTA’s registered-person confirmation where appropriate, but remember that NZTA does not record legal ownership: the registered person is responsible for the vehicle and is not necessarily the legal owner.
Be cautious if the seller will not meet at a traceable location, refuses identity or documentation checks, wants payment before inspection, or tells you to buy a report from an unfamiliar website. Keep the original listing, messages and representations.
Match the number plate and VIN
Compare the physical registration plates, VIN or chassis number, make, model, year and colour with the documents and every electronic result. Inspect identifier plates for damage or alteration and ask about replacement plates or re-registration history.
PPSR recommends using the VIN because a registration number can change. A plate-only match should not override a different VIN, and a report for the wrong vehicle is useless even when every displayed status appears clear.

Check rego, WOF or COF and RUC
Confirm the vehicle licence commonly called rego, the applicable WOF or COF and any required RUC information. Compare dates and the RUC end distance with the current odometer. Understand whether an expired or missing result prevents lawful road use or creates an immediate cost.
Do not treat a valid WOF as a mechanical warranty. NZTA says it is not a pre-purchase inspection and does not cover important engine, clutch, gearbox, differential and other condition checks.
Check stolen status and money owing
Search New Zealand Police using the plate and, where appropriate, the VIN, engine or chassis number. Police warns that the stolen data is a snapshot and can omit theft that has not been reported or has not yet reached the database.
Search PPSR for registered financing statements or use a report that explicitly includes an appropriate current money-owing check. The Companies Office currently lists a motor-vehicle PPSR search at NZ$2 plus GST. Save the dated result and resolve every match before payment.
Review odometer, import and damage history
Compare the displayed odometer with inspection and service records. Look for readings that decrease, long gaps, unusually low distance relative to wear, or seller claims that do not match the record. A consistent electronic history still cannot prove that every reading is genuine.
For an imported vehicle, investigate information from the country of origin where available. New Zealand reports may not contain every overseas accident, auction, flood, write-off or repair event, and the scope differs by provider and product.
Inspect and test-drive the car
View the vehicle in daylight and, if possible, start it from cold. Check tyres, lights, windows, controls, warning lights, leaks, smoke, unusual smells, corrosion, paint differences and uneven panel gaps. During the test drive, assess braking, steering, vibration, transmission behaviour and unusual noises safely.
For an EV, check usable battery health or diagnostic evidence, charging inlets and supplied equipment, remaining battery warranty and software or recall status. Use an inspector experienced with the vehicle type, particularly for EVs, hybrids or uncommon imports.
Arrange an independent pre-purchase inspection
Consumer Protection says the best way to avoid a problem is an inspection by a mechanic or pre-purchase inspection service, particularly for a private purchase. Choose an independent inspector rather than relying only on a seller’s preferred provider.
Ask the inspector to explain urgent safety work, likely near-term maintenance and items they could not assess. A report should inform the price and decision; it does not force you to continue with a vehicle that presents unexplained risk.
Before paying and changing the registered person
Read the sale agreement, confirm the agreed vehicle and price, record known faults and conditions, and use a traceable payment method. Both buyer and seller must notify NZTA when the vehicle changes hands, and NZTA recommends completing the online transactions at the time of sale.
Private buyers generally have fewer consumer-law protections than buyers purchasing from a registered motor vehicle trader. Do not transfer money merely because the seller says another buyer is waiting; complete the evidence and inspection needed for the value and risk involved.
Frequently asked questions
What should I check before buying a used car in NZ?
Check the seller, plate and VIN, licence, WOF or COF, RUC, stolen status, PPSR, odometer and history, then test-drive and arrange an independent inspection.
How do I check if money is owing on a car?
Search the official PPSR using appropriate vehicle identifiers or buy a report that explicitly includes a current security-interest check. Investigate every matching financing statement.
Does a WOF mean a used car is safe to buy?
No. A WOF checks specified safety standards at an inspection point but is not a mechanical pre-purchase inspection and does not cover every component or fault.
Should I use CarJam or MotorWeb before buying?
Either can provide useful packaged history information. Compare current coverage, timestamps, price and terms, and do not let one clear report replace seller, PPSR, Police and mechanical checks.
How do I confirm the seller owns the car?
NZTA can confirm a registered person, but registration is not conclusive legal ownership. Check identity, authority to sell, purchase documents and registered security interests.
What should I check when buying a used EV?
In addition to normal checks, investigate usable battery health, diagnostic evidence, charging compatibility and equipment, battery warranty, recalls and inspection by an EV-experienced technician.
Do I need a pre-purchase inspection with a clear history report?
Yes. A history report cannot assess current mechanical condition, hidden physical damage, battery degradation or every emerging fault.
What happens after I buy a used vehicle?
Both buyer and seller must promptly notify NZTA so the registered-person change is completed. Keep the agreement, payment evidence, reports and inspection records.
