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. The road remains closed ahead of a serious crash unit investigation.

“Police are aware that a number of tourists are in Milford Sound, or wanting to travel there, and thank them for their patience.”

Authorities are urging motorists travelling to or from Milford Sound should postpone travel and expect delays due to the state highway closure.

Waka Kotahi NZTA said a further update on the closure would be expected in the late afternoon. SH94 is currently closed between Monkey Creek and Homer Tunnel.
