"A lot of the guys, they will either walk up to the crater or go up just for a ski at the end of the day.''
Mr McGill said he did not know exactly what happened after that.
"He's obviously slipped while he was skiing or while he was walking up the slopes there.''
Mr Hofer was rostered off on Friday and the skifield was closed the following day. He was reported missing on Saturday.
Mr McGill did not know Mr Hofer personally but colleagues said he was "a nice guy, a pretty quiet sort of a guy'' who enjoyed his work on the mountain.
"Everyone's obviously very upset and it's a real tragedy, losing a colleague like that.''
Mr Hofer lived by himself in a room at a backpackers in National Park.
It was his first season working at the skifield.
Constable Conrad Smith of National Park police said the Italian consulate had advised Mr Hofer's next of kin.
Police were investigating the death on behalf of the coroner.
A post mortem examination would be carried out at Taumaranui Hospital.
