Odometer tampering will not be tolerated
In Tauranga, a used car dealer has been brought before the law for quietly erasing more than 30,000 kilometres from a vehicle's history before selling it to an unsuspecting buyer — a deception that endured for over a year before a routine service visit exposed the truth. The case, the first successful prosecution of its kind in New Zealand, reminds us that trust in commerce is fragile, and that the small manipulations of numbers can carry real consequences for safety, fairness, and the integrity of everyday exchange.
- A buyer paid $24,000 for a car they believed had travelled 119,000km — unaware the true reading was over 150,000km, a gap that affects reliability, safety, and value.
- The deception held for sixteen months, surviving daily use, until a routine service appointment revealed that the odometer and the maintenance records simply could not both be telling the truth.
- MBIE launched an investigation, confirmed deliberate tampering, and pursued charges under the Motor Vehicle Sales Act 2003 — resulting in New Zealand's first successful odometer fraud prosecution.
- The dealer agreed to repurchase the vehicle at the original sale price, but the court went further, ordering $1,000 in reparation for emotional harm and a $5,000 company fine.
- Regulators are signalling that this conviction is a turning point — a warning to the used car industry that deceptive trading practices will now be pursued through to conviction.
A Tauranga car dealer has been sentenced in what marks New Zealand's first successful prosecution for odometer tampering, a case that exposes the quiet vulnerabilities of the used vehicle market.
Sachinthaka Nagasinghe, sole director of Carporium, bought a Toyota RAV4 at auction in December 2023 with an odometer reading of 150,031 kilometres. When he sold it to a private buyer two months later for $24,000, the display showed 119,244 kilometres — a reduction of more than 30,000 kilometres that was physically impossible without interference.
The buyer had no cause for suspicion and drove the car for over a year. It was only during a routine service in May 2025 that technicians noticed the odometer contradicted the vehicle's recorded maintenance history. The discrepancy was reported to the NZ Transport Agency, triggering an MBIE investigation that confirmed deliberate tampering.
Facing two charges under the Motor Vehicle Sales Act 2003, Nagasinghe agreed before sentencing to buy the car back at the original $24,000 price, restoring the buyer's financial loss. The Tauranga District Court nonetheless ordered $1,000 in reparation for emotional harm and fined his company $5,000.
MBIE's national manager of occupational regulation, Bevan Yee, described the outcome as a watershed moment, stressing that falsified mileage misleads buyers about a vehicle's true condition, safety, and maintenance needs. The agency's message was unambiguous: deceptive trading practices will be pursued, and this conviction signals that enforcement is no longer a distant prospect for those who undermine consumer trust.
A Tauranga car dealer has been sentenced for systematically deceiving a buyer about the true mileage of a Toyota RAV4, a case that marks the first successful prosecution of its kind in New Zealand and signals a harder line on fraud in the used car market.
The scheme unraveled slowly. In December 2023, Sachinthaka Nagasinghe, the sole director of Sachis Holdings Ltd trading as Carporium, purchased a RAV4 at an Auckland car auction. The odometer read 150,031 kilometers. Three months later, in February 2024, he sold the same vehicle to a private buyer for $24,000. This time, the odometer showed 119,244 kilometers—a difference of more than 30,000 kilometers that should have been impossible.
The buyer had no reason to suspect anything was wrong. They drove the car for over a year before taking it in for routine maintenance. It was there, in May 2025, that service technicians noticed something didn't add up. The odometer reading didn't match the vehicle's recorded service history. The discrepancy was flagged to the Registrar of Motor Vehicle Traders through the NZ Transport Agency Waka Kotahi. An investigation by the Ministry of Business, Innovation & Employment confirmed what the numbers suggested: the odometer had been deliberately tampered with.
Nagasinghe faced two charges under the Motor Vehicle Sales Act 2003—one for tampering with an odometer without reasonable excuse, and another for aiding and abetting his company in the offense. Before sentencing, he agreed to buy the car back from the buyer for the same $24,000 they had paid, effectively undoing the financial harm of the transaction itself. But the court's response went further. In the Tauranga District Court, Nagasinghe was ordered to pay $1,000 in reparation for emotional harm to the buyer. His company, Carporium, was fined $5,000.
Bevan Yee, national manager of occupational regulation at MBIE, called the case a watershed moment. This was the first successful prosecution demonstrating the agency's willingness to pursue odometer tampering cases to conviction. Yee emphasized that accurate vehicle information is not a luxury—it is fundamental to fair trading. When mileage is falsified, buyers can end up overpaying for a vehicle and may be misled about its safety, reliability, and maintenance requirements. A car with 150,000 kilometers on it is not the same as one with 120,000 kilometers, and the difference matters.
The message from MBIE was direct: odometer tampering and other deceptive practices will not be tolerated. Most traders, Yee noted, do the right thing and deserve to operate in a marketplace where unlawful behavior is identified and addressed. This case signals that enforcement action will follow when conduct undermines consumer confidence and damages the reputation of the industry. For a buyer who discovered the truth only by accident, more than a year after handing over their money, the lesson came late—but it came.

La Conversación del Hearth Otra perspectiva de la historia
Why did it take so long for the buyer to realize what had happened?
The odometer tampering was hidden in plain sight. The buyer had no reason to distrust the reading when they bought the car. It wasn't until they took it for scheduled maintenance that technicians cross-referenced the odometer against the service history and saw the numbers didn't match. That's when the fraud became visible.
How does someone even tamper with an odometer in a modern car?
The source doesn't explain the mechanics of it, but the fact that it was done and then detected suggests it's possible—and that's precisely why regulators are concerned. The buyer could have driven that car for years thinking it had 120,000 kilometers when it actually had 150,000. That affects everything from resale value to maintenance schedules.
Was this dealer running a systematic operation, or was it a one-off?
The source only documents this single case, so we can't say whether Nagasinghe was doing this routinely or if this was an isolated incident. But the fact that MBIE called it the first successful prosecution suggests they've been watching the industry and waiting for a case they could prove.
What does the $1,000 reparation actually mean to the buyer?
It's symbolic more than compensatory. The real remedy was buying the car back at the original price. The $1,000 acknowledges the emotional harm of discovering you were deceived—the violation of trust, the time spent investigating, the worry about what else might be wrong with the vehicle.
Why is MBIE making such a public statement about this?
Because they want other dealers to know they're watching, and they want consumers to know that enforcement is real. If traders think they can get away with odometer tampering, they'll keep doing it. This case is meant to change that calculation.
