One person has died after a car and truck collided south of Dunedin today.
Police say a vehicle travelling north collided with a truck travelling south on State Highway 1, near Milton.
A van following the other vehicle had to take evasive action to avoid the crash and has gone into a ditch.
Police say one person died at the scene. The road is expected to be closed for some time, but there are diversions down Adams Flat Road and Creighton Road.
Trucks may not be able to use the diversions and motorists are advised to expect delays.
The Serious Crash Unit are investigating the cause of the crash.
