An elderly woman oblivious she was being chased by police for 25 minutes only stopped when her car was spiked on a state highway south of Rotorua.
Rotorua area commander Inspector Bruce Horne said officers received several reports from concerned motorists about a vehicle being driven in an erratic manner on State Highway 5 about 12.20pm yesterday.
"A few minutes later the vehicle was located by police heading south along SH5,'' he said.
"As the police patrol approached the vehicle the officers also observed the vehicle being driven in a very erratic manner.''
Mr Horne said officers signalled to the driver to stop by turning on the car's lights and sirens, but the driver did not pull over.
