Initial interviews with witnesses to Saturday's fatal Helicopter Line crash on Mt Alta, near Wanaka, are expected to be completed today or tomorrow morning.
Jerome Box (52), of Auckland, was killed in the crash and six other men on board were injured while on a Harris Mountains Heli-Ski trip.
Transport Accident Investigation Commission general manager communications and investigation support Peter Northcote said two investigators spent yesterday gathering documentary evidence and conducting interviews in the Queenstown area.
The helicopter wreckage was transported across Lake Wanaka by barge on Monday night and would be taken to the commission's Wellington technical facility for further examination later this week.
Harris Mountains Heli-Ski and Helicopter Line director Mark Quickfall said the company's normal heli-ski operations had resumed.
The pilot of the crashed helicopter Dave Matthews and heli-ski guide Mark Sedon were both recovering at home, Mr Quickfall said.
''Mark remains housebound with injuries including broken bones, bruises and abrasions.
''However, he is healing and looks forward to being back on skis by season's end.''
