A Far North woman with three young children in her car - one of them a four-week-old baby - was allegedly more than four times over the alcohol limit when she refused to stop for police.
Sergeant Haydn Korach said an officer tried to stop the 38-year-old about 9pm on Friday after a member of the public complained about her driving.
He said she allegedly refused to stop and instead led police on a low-speed chase, averaging about 25km/h, along Waitehuia Rd and Roma Rd near Ahipara.
Mr Korach said she was breath-tested when she eventually stopped, recording an alcohol level of 1089 micrograms per litre of breath. The legal limit is 250mcg.
The woman had two four-year-olds in the car and a four-week-old baby, he said.
