A man is in a critical condition after his car went off a bridge near Blenheim last night.
Ambulance communications spokeswoman Sharleen Murtha said the car was fortunate to land on a sand bar when it left State Highway 6 over the Wairau River about 11.30pm.
The man was taken by helicopter to Wellington Hospital in a critical condition.
In Dunedin, a teenager was trapped in a car for about an hour when it smashed into a power pole about 3.50am.
The crash, on East Taieri-Allanton Rd, "split the car in two", Ms Murtha said.
