Wellington Police say they are disappointed after a checkpoint last night caught 25 drivers on their cellphones in just over an hour.
The checkpoint was set up on State Highway 1 in Pukerua Bay, in northern Porirua, Sergeant Laurence Vautier of Wellington Road Policing said.
He said drivers found to be using a phone can be expected to receive an instant fine of $80 and 20 demerit points.
Mr Vautier encouraged passengers in cars with a driver using a phone to speak up.
From the 18th to the 21st of February, Wellington Police will be running a campaign across the district focusing on distracted drivers.
