One motorcyclist has been killed, and two other riders are injured after a serious crash near Milford Sound on State Highway 94.

Emergency services were called to the crash, just south of the Homer Tunnel in Fiordland, at about 10.50am.

“The crash occurred about 10.50am and involved three motorbikes,” police said.

“Sadly, one of the riders died at the scene, while two others suffered moderate-to-serious injuries.

State Highway 94 has since re-opened following the crash.

Authorities earlier urged motorists travelling to or from Milford Sound to postpone travel and expect delays.

“Police would like to thank all those impacted by the road closure for their patience and cooperation.”

Waka Kotahi NZTA said SH94 was closed earlier between Monkey Creek and Homer Tunnel.
