A 59-year-old motorcyclist was killed in a collision with a camper van north of Haast early this afternoon.
Steven Wayne Nottingham, of Christchurch, was riding south on his Harley Davidson with one other motorbike when he collided with a north-bound campervan on a winding stretch of SH6, police said in a statement.
There were no other known injuries. Three people were in the campervan.
A serious crash investigation is under way, and motorists in the area were advised to expect delays.
