One person is seriously injured and three others have moderate injuries after a car crossed the centre line and crashed into another vehicle in Upper Hutt this morning, police say.
The incident happened on State Highway 2 between Totara Park and Gibbons Street just before 6.30am, Senior Sergeant Marc Clausen of central police communications said.
The crash happened when a northbound car, with one person inside, drifted into the lane of the southbound vehicle, which was carrying three people, he said.
Following the incident, there was another minor nose-to-tail accident involving vehicles slowing down for the first crash.
A spokesman for Wellington Free Ambulance said a woman in her mid 20s, who was the rear seat occupant of the southbound vehicle, was flown to Wellington Hospital by the Westpac Rescue Helicopter with spinal and abdominal injuries.
