The police have accidentally ticketed tens of thousands of people for traffic offences they haven't committed.
They say a computer glitch meant information from the Transport Agency between mid-October and mid-December was not updated in the police system - affecting about 20,000 traffic infringement notices.
The police say those wrongly fined include people who sold their vehicles during the two-month period and were ticketed for offences carried out by the new owners or others driving the vehicles.
They say they only became aware of the problem after it was raised by someone who had been wrongly ticketed.
The police say anyone incorrectly ticketed will not have to pay.
The police say they've fixed the computer glitch but are still working out what caused it.
Police Minister Anne Tolley says she's disappointed by the mistake, which she was told about on Tuesday morning, and it's a reminder to the police to be vigilant about their computer systems.
