The recovery operation has resumed at Fox Glacier this morning.

The first teams of Police search and rescue staff, along with Aoraki-Mt Cook Alpine Cliff Rescue and Fox Glacier Alpine Cliff Rescue crews set off in helicopters about 6am.

The Police Disaster Victim Identification Team spent the night at Chancellor Hutt on Fox Glacier to facilitate the swift return this morning.

Members of the Traffic Accident Investigation Commission team are also on site making a total of 26 personnel on the glacier at present.

The weather in the area is extremely changeable and rescue teams are hoping the current window will allow enough time to locate and recover the remaining three victims along with other evidence from the scene.
