When you’re shopping for a used car, one of the biggest risks is getting misled about how far it’s actually been driven. Odometer fraud – also known as clocking or winding back – happens when a seller illegally reduces the mileage on a car to make it seem newer, more valuable, or better maintained than it really is.

While most sellers are genuine, odometer tampering does still happen in New Zealand, especially with imports. Here’s how to spot the warning signs and protect yourself.

Check the Car’s History

The safest way to confirm mileage is to get a vehicle history report.

  • NZTA and agencies like CarJam can show the odometer readings recorded at each WOF inspection.
  • Sudden drops or inconsistent numbers are a red flag.

👉🏼 Top Tip: Always compare the current odometer with the history before you buy.

Look for Wear and Tear

The mileage should match the car’s condition.

  • Steering wheel, pedals, and seats – excessive wear suggests higher mileage.
  • Stone chips, faded paint, or worn tyres – may indicate more years on the road than shown.
  • New carpets or pedal covers – sometimes used to hide wear.

Check the Service Records

Legitimate cars should have regular servicing documented.

  • Look for stamps in the service book, or invoices with mileage recorded.
  • Be wary if records are missing, incomplete, or don’t match the odometer reading.

Trust the Tech

Modern cars often store mileage in multiple places.

  • Some scan tools can check readings in the ECU or transmission.
  • If you’re unsure, get a pre-purchase inspection – mechanics know where to look for signs of tampering.

Be Wary of “Too Good to Be True” Deals

If the price, condition, and mileage don’t add up – trust your gut. Low kilometres on an older import can sometimes signal odometer tampering.

Why It Matters

Odometer fraud doesn’t just cost you money upfront – it can also mean unexpected repairs, higher running costs, and lower resale value.

👉🏼 Bottom line: Do your homework, check the history, and if in doubt, walk away.
