Bad weather prompted police to pull out of a high-speed pursuit of a convoy of four vehicles in Auckland late last night.
Officers were dispatched to two locations after reports of an attempted burglary and vehicles being interfered with shortly before midnight. While on their way, a patrol saw four vehicles driving at excessive speed in convoy.
All vehicles failed to stop. They reached speeds of 90 km/h in a 50km/h zone before heading south on the motorway, reaching speeds of 110 km/h in an 80km/h zone, police said.
The patrol abandoned the pursuit because of the conditions and soon after two of the four vehicles being chased hit the motorway median barrier.
At least two people ran off and are still wanted.
No one else was involved with the crashes.
The other vehicles sped off and one was later found in Arbor Place, Clendon where three people described by police as "youths" ran off.
The fourth vehicle has not been found.
One of the vehicles had stolen number plates fixed to it.
Anyone with information about the incidents should call Auckland police on (09) 571 2800 or Crimestoppers, anonymously, on 0800 555111.
