Police are clamping down on personalised number plates they say are confusing.
Christchurch motorists with plates using combinations of letters and numbers have received letters from police saying they intend cancelling them because they are not easily readable and are "not in the interest of road safety".
Police can apply to NZ Transport Agency (NZTA) - which authorises them - to have the plates cancelled.
One motorist contacted APNZ to complain about the letter he received from a Christchurch police officer intending to cancel his plate.
He refused to give his name, or his plate, but said it was a combination of numbers and letters.
