Bought a used car in NZ? Your first 7 days checklist (2026)

Day 0: payment and paperwork

Pay by traceable bank transfer, never cash in an envelope, and pay only after you have inspected and test-driven the car. Get a signed receipt naming both parties, with the date, price, plate number, VIN or chassis number and the odometer reading — this piece of paper is what untangles any later dispute with the seller or with NZTA. Collect whatever exists of the service history, both keys if promised, and the current WOF details. Photograph the car at handover: existing scratches have a way of being remembered differently a week later.

Day 0–1: transfer the registration online

Both the buyer and the seller must notify NZTA of the change of registered person within seven days — do your part the same day, online, with the plate number and a New Zealand driver licence or realme login. The transfer fee is small and yours to pay. Until your notification is processed you are driving on the previous owner's record, which matters if a speed camera or a police check shows up in week one. If the seller is slow with their half, chase them: their delay becomes your paperwork problem.

Day 1: the WOF and rego reality check

Before your first proper drive, confirm where the car stands: WOF expiry, rego expiry, and how close each one is. A WOF due within weeks is an immediate cost — book the inspection now and budget for the items it finds. Driving without a current WOF or licence is an infringement offence, and the exemptions for driving to an inspection are narrow. If the rego is on hold, re-license before you drive on public roads at all. Ten minutes with the plate in the NZTA lookup settles all of it.

Day 1: insurance from the moment you own it

Insure the car from the day of handover, not from the day you first drive it — a car parked on the street can still be hit, and third-party cover is the minimum that stops you paying for someone else's expensive repairs. Insurers will want the plate, the odometer, the registered person's details and the purchase price; some also ask who the main driver is and where the car is parked overnight. If you hold a learner or restricted licence, say so upfront — non-disclosure is the classic way a claim gets declined.

Days 2–3: diesel buyers keep the RUC chain unbroken

If the car is a diesel, RUC becomes your routine from handover. The licence you inherited may cover a few hundred more kilometres, or none; either way, buy your own RUC licence through NZTA — online or at an agent — before the inherited distance runs out. Keep the odometer honest and keep the receipts: RUC is audited against WOF readings, and uncovered kilometres accumulate as a liability you settle later. Electric vehicles joined the same system in April 2024 and buy distance the same way; petrol cars are the only ones who can ignore all of this.

Week 1: the mechanical self-check

You bought it, so now you own its condition. Check engine oil and coolant cold, on level ground. Examine each tyre for cuts and measure the tread — the legal minimum is 1.5 mm, and smart money buys before you get there. Test every light, both wiper speeds, and the handbrake on a slope. Listen on a quiet street: an even idle, no scraping at full steering lock, no whine that rises with speed. If the service records have a gap, book a service now — fresh oil, a new filter and a dated receipt are the cheapest insurance you will ever buy, and they start your own maintenance clock.

Week 1: know what you now own

Your car's value is not frozen at the purchase price. Over the first week, watch how the same model is doing on Trade Me — what others ask, how quickly comparable cars move, whether sellers cut. It calibrates your running costs against depreciation and quietly settles the future question: when swap day comes, you will already know what this car is worth instead of taking the first dealer number offered. Nothing new is required — it is the same report you used to buy it, read from the other side.

When swap day comes

When the swap day comes, start with our free sell advice: enter your car's details and see what your car should ask for on Trade Me today — then decide whether this week's market says sell or wait, and list with confidence.
