Several children have been injured after a bus and tanker carrying hot tar collided in Canterbury.
Police say the children suffered minor injuries following the crash on State Highway 1 at Fairfield, near Ashburton, on Wednesday.
A St John Ambulance spokesperson says five people have been taken to Ashburton Hospital.
The crash sent the tar spilling across the road, causing part of the highway to be closed.
Detours are in place.
