Whanganui police are asking for witnesses after an accident involving a motorbike and a ute in Aramoho, Whanganui.

A police spokesperson said a report of the crash was received around 12.30pm on Wednesday.

Officer in charge of the Whanganui Road Policing Group Sergeant Colin Wright said a white ute was seen turning right off Somme Pde into the Aramoho Shopping Centre.

A blue offroad motorbike travelling in the same direction then hit the ute on the driver’s side door.

The rider of the bike, a 23-year-old male, was not wearing a helmet and Wright said he suffered head and abdominal injuries in the crash.
