One person is in hospital after getting hit by a truck while fleeing from a car crash on an Auckland motorway this morning.
The Northwestern Motorway near Massey in Auckland was closed for four hours following the crash, with vehicles involved on both sides of the motorway.
Emergency services responded to a single-vehicle crash in the southbound lane, near the Royal Rd on-ramp around 1.15am.
Following the crash the driver fled from their vehicle and was struck by a vehicle while attempting to run across the northbound lanes, police said.
The person was taken to hospital and is in a serious condition.
On the northbound side of the road, a mangled silver car could be seen resting on the barrier.
A white Actus-branded tanker truck was stopped in the central lane with what appeared to be blood visible on the passenger side, on the southbound side of the road.
As a result of both incidents, a section of the motorway northbound near Lincoln Rd was closed for a short time.
The Serious Crash Unit was in attendance and an investigation into the crashes is under way.
Fire and Emergency NZ attended the job but referred NZME to police for further information.
Police blocked the citybound route from Triangle Rd. NZTA traffic cameras appear to show the motorway has since reopened.
The woman was recovered from the water and received CPR.
