Police have released the name of a teenager who was killed when his moped and a four wheel-drive vehicle collided in Christchurch last night.

He was Judah Maier, 19, of Christchurch.

A police spokesman said emergency services were called just before 8pm to the crash on the southern motorway (State Highway 73) around the Lincoln Road overbridge at Spreydon.

Emergency services remained at the scene for much of last night and the road was closed for some time.
