A drink-driver nabbed speeding with several children in the car, including an unrestrained child and a dog in the back, was a recipe for disaster, police say.
The incident was one of two Whangarei police dealt with on Friday night which they say could have ended tragically.
Three teenage males were in a car which hit a tree after allegedly racing through a suburban street in excess of 100km/h.
Whangarei Highway Patrol Sergeant Chris Goodall said officers pulled over the first vehicle just before 7pm after they clocked it at more than 125km/h between Waipu and Ruakaka.
Both the female driver and her passenger, the mother of the children, had been drinking.
