The paths were not well-defined and climbers often went off the beaten track, which meant they could lose their route or sense of orientation.
“In poor visibility, people do struggle.”
Injuries such as sprains or fractures were another common issue that stopped people from being able to walk back down the mountain.
Whanganui-Ruapehu district SAR co-ordinator Constable Conrad Smith said people climbing Mt Ruapehu ill-prepared were causing “a bit of a headache” for search and rescue teams.
The Sky Waka Gondola now took people up to the Knoll Ridge Chalet, which meant people could be as high as 2000-2040m and could carry on walking higher up the mountain.
They could easily get stuck if they missed the gondola back down or were caught in bad weather.
Smith said Ruapehu Alpine Lifts was doing good work around marking trails and safety messaging, but some visitors arrived unprepared.
Zimmer said he had seen examples of people wanting to get hikes done within a short time window, regardless of the weather conditions or how they were feeling on the day.
It was important to know your limits, he said.
“Know what you can do, and if you are actually fit enough, prepared enough and have the right equipment to achieve your goal.”
To successfully navigate on Mt Ruapehu, people needed good local knowledge, a map and compass and a personal locator beacon.
Smith said people wanting to climb high on Mt Ruapehu needed to talk to Department of Conservation staff at the visitor centre about what gear to take and which routes were viable.
“There’s a lot more risk on Ruapehu. It’s a lot higher, more altitude, you’ve got the volcano as well that’s active.”
Visitors needed a high level of fitness, equipment and knowledge, he said.
