The man who died in front of his wife and daughter after falling from a 14 metre high-ropes adventure course was Auckland man Clifford Brabet.

Police named the 57-year-old, from Titirangi, this morning.

Brabet was with his wife and daughter when he fell from high wires at Tree Adventures in Woodhill Forest near Helensville, Auckland, yesterday.

He was an electrical engineer and a computer systems manager.

Safety inspectors from the Ministry of Business, Innovation and Employment were due at the park today. The ministry would not make any comment on the nature of the investigation.

Tree Adventures, which operates 110 high-wire activities and flying foxes at the park, said that safety was always a "number-one priority" and yesterday was "no exception".

"We insist on lengthy and detailed safety briefing prior to anyone using the course, as well as ongoing supervision from Tree Adventures staff throughout participants' use of the courses," the company said.

The park had been closed and the company was working with police and the Department of Labour to find out what happened.

"The events of [yesterday] are an absolute tragedy and we extend our deepest condolences to the family members and friends," the company said.

A witness who saw the fall, Imogene Pyne, was unwilling to comment on the Tree Adventure statement.

She said she saw paramedics trying to resuscitate Brabet for 15 minutes and heard a girl call out for her father from the trees.

On Tree Adventure's Facebook site today a number of people have come out in support of the operation.

"You guys do a super job, keep it up," Julie Wright-Winslow wrote.

Jess Wallace said she was annoyed that a witness had said safety was lacking.

"In my experience at tree adventures they were so professional and I felt completely safe," she said.

Daisy Moore said "I have always felt so safe", while Paul Nimmo said the safety regime was one of the best he had seen.

Sheena Pink said her many experiences with school groups showed her that "safety briefing very thorough and staff were always scattered around the park keeping an eye on the kids".

Tania Mita-Pengelly said she had an awesome time there "and have to say safety was the big thing pointed out many many times by the trainer we had safety first always".

Aimee Evans said she would go back, saying: "When I went with my family a few years back we were not allowed to start the course until the instructor felt confident we had listened to the safety briefing and were following it."
