Heavy snowfall in the Tongariro National Park has prompted a warning about avalanches and snow covered crevasses from the Department of Conservation.
Hikers and climbers above the snowline on Mt Ruapehu, Tongariro, and Ngauruhoe should be aware of hazards they may not be used to.
Alpine hazards which posed risks to inexperienced people now included avalanches and thinly snow-covered crevasses, especially on Mt Ruapehu outside the ski area, thin ice on the higher lakes on Mt Tongariro, and thinly covered holes or warm ground on Mt Ngauruhoe and Mt Ruapehu.
Such holes may contain volcanic gas.
Steep icy slopes on all peaks need to be approached with caution. Alpine equipment and experience, including training for avalanche conditions, are necessary to proceed safely into the higher elevations of Tongariro National Park.
In addition, warm clothing and boots suitable for alpine conditions are also necessary.
