A 14-year-old boy is in hospital with serious spinal injuries after an erratic driver hit three cars on Auckland's North Shore last night.
Police said a vehicle was seen driving erratically on the Harbour Bridge about 6.15pm.
It got off at the Onewa Rd exit where it swiped a car which had stopped at traffic lights, before flying across the road and hitting a parked car.
The vehicle then travelled about 500m up the road and collided head-on with an oncoming vehicle.
Five people were injured, three seriously.
