Northland's top roading cop is "horrified and astounded" after a driver was stopped allegedly doing 165km/h on a busy stretch of Northland state highway.
The alleged speedster was caught on Wednesday afternoon - within days of Queen's Birthday weekend, when 11 people died in road accidents across New Zealand, three in Northland.
It was the holiday weekend's worst road toll in 27 years and had police clamouring for people to take care and slow down.
Northland road policing manager Inspector Wayne Ewers said the man was stopped about 1.45pm as he drove along State Highway 1 at Uretiti, south of Whangarei.
Mr Ewers said he was "horrified and astounded" by the man's behaviour.
