Two motorcycle riders were treated in hospital on Saturday after a serious collision in Smiths.
A female rider exited Zuills Park Road and attempted to make a right turn west on South Road at about 4.40pm.
A motorcycle ridden by a male was headed in the opposite direction along South Road, and the two collided. Both were taken by ambulance to King Edward VII Memorial Hospital.
The spokesman said the extent of their injuries was unknown.
Traffic was diverted from the area as investigators and officers from the Forensic Support Unit examined the scene.
