The tragedy comes during a deadly season, with four other climbers killed or missing.

Almost $150,000 has been raised for the family of late mountain guide Thomas Vialletet, who died on Aoraki/Mt Cook in November.

A Givealittle page was set up by friends to support Vialletet’s partner Danielle and their two young children.

Donations have come from New Zealand and around the globe, reflecting the impact the acclaimed climber had while guiding local and international clients.

Wanaka-based mountain guide Thomas Vialletet died when he fell from Aoraki / Mt Cook in November.

The page says he was a devoted father, and touched the lives of countless clients and friends.

“So deeply saddened to hear of the loss of a wonderful and talented man. We will never forget our incredible experience when he guided us in La Grave many years ago. He will be greatly missed,” one private contributor wrote.

Vialletet was known as a highly skilled alpinist.

Only weeks before the accident, Vialletet had guided climbers across Aoraki’s demanding East Ridge in a 25-hour round trip from Plateau Hut.

In a social media post, Vialletet believed it had been a decade since the route was last guided.

He grew up in the French Alps, where he climbed and skied, later becoming part of the French National Young Alpinism Team between 2009 and 2012.

Vialletet later came to New Zealand and fell in love with its mountains and wilderness, becoming a climbing instructor before qualifying as a full IFMGA Mountain and ski guide.

Since the accident, two further alpinists have died climbing in New Zealand’s mountains.

Last weekend Connor Scott McKenzie, 28, a dual citizen of New Zealand and Canada, and Tanmay Shetankumar Bhati, 23, died while attempting the steep rock of Sabre Peak’s North Buttress in Fiordland.

Both men lived in Australia.

Another pair of climbers remain missing on Aoraki/Mt Cook. Earlier this week, searchers in helicopters scanned the route the climbers took to the summit, but nothing has been found.

The search is continuing.
