Wellington's Mount Victoria tunnel has reopened, three hours after a serious car crash that left two people injured.
Wellington Free Ambulance spokeswoman Sarah Coulthard said one person was in a critical condition and the other had moderate injuries after the crash.
Wellington Hospital spokesman Chas Te Runa said both patients were in the hospital's emergency department. One person was in critical condition and the other was in stable condition.
The crash occurred just after 6am outside the Mount Victoria Tunnel, police said. The tunnel reopened three hours later, shortly before 9am. The tunnel footpath was reopened for pedestrians and cyclists briefly before the tunnel reopened.
The tunnel, on State Highway 1, is a vital link between the city centre to the west and the eastern suburbs and Wellington International Airport.
Fire and Emergency shift manager Jill Webley said two fire trucks have left the scene after emergency workers helped free one person from the vehicle who was trapped.
A white Nissan could be seen crashed into the fence of Wellington College's rugby field with a badly smashed windshield and the top half of the car had been cut off by Fire & Emergency workers. A black suit jacket could be seen draped over the driver's seat of the car.
A black SUV was also involved in the crash. It could be seen parked haphazardly near the Wellington College exit with its front completely crumpled.
New Zealand Transport Agency said those travelling to Newtown or Harbour Bays should expect delays.
The Serious Crash Unit is investigating the crash.
