One person is in a serious condition after a fleeing vehicle crashed into a truck in South Auckland.
Police say about 1.20pm, they received complaints from the public about the vehicle driving erratically in the Weymouth area.
The vehicle was found soon afterwards on Roscommon Rd, but police say it fled onto the Southwestern Motorway when signalled to stop.
Police did not pursue the vehicle, which took the Lambie Drive off-ramp and collided with a stationary truck at the intersection.
