Huelsmann, 57, had three children and three grandchildren, Bould said. He was a clinical psychologist and practised across Wellington.
Huelsmann specialised in sports psychology and helped write a book, ACT in Sport: Improve Performance through Mindfulness, Acceptance, and Commitment.
New Zealand women’s underwater hockey coach Rebecca Brosnan said Huelsmann’s psychological training of both men’s and women’s teams was a key part in them winning the 2018 World Championships.
High jump bronze medalist Imogen Skelton credited Heulsmann with teaching her that “training the mind is just as important as training the body” to succeed in sport.
He had been in New Zealand “for a long time” after moving from Germany, Bould said.
Huelsmann was once National Psychology Advisor for ACC, according to a social media post from Accuro Health Insurance.
Huelsmann lived in New Zealand for at least 20 years, working in child and adolescent mental health as well as pain and injury rehabilitation.
Bould said he was a keen tramper and had a hiking partner with him when he died.
Police were called to a report a person was critically injured on the mountain about 4pm on Sunday.
Police extended their condolences to Huelsmann’s family and friends.
Police Search and Rescue, assisted by the Taranaki Rescue Helicopter Trust team and members of the Taranaki Alpine Cliff Rescue team, worked to recover Huelsmann’s body.
Inquiries into the incident were ongoing, but police had completed their inquiries on behalf of the Coroner who would release their findings “in due course”, a police spokeswoman said.
Taranaki Alpine Cliff Rescue member Jeremy Beckers flew to the incident by rescue helicopter just after sunset on Sunday.
“The death of the tramper yesterday is a reminder of the inherent risks of recreation in the alpine environment. People planning to visit Taranaki Maunga and undertake these activities need to understand the danger the mountain presents.
“Our condolences go to those impacted by yesterday’s incident,” Hopkins said.
Taranaki Mountain Shuttles won’t operate on Tuesday and Wednesday while the company observes a rahui “out of respect and cultural protocol” after the death.
The bus company said the rahui would last two days “or as long as directed”.
