After a blanketing of snow throughout the South, adventurers headed to the mountains are being warned of the danger of avalanches.
The storm system that swept over the country earlier this week brought about a sweep of fresh snow, but has also significantly increased the avalanche danger across most mountainous areas.
The New Zealand Avalanche Advisory labelled the avalanche danger as "considerable" for most of the country.
Mountain Safety Council chief executive Mike Daisley said only highly experienced and well-equipped people should consider back-country travel in avalanche terrain during this time.
"While skifields have been carrying out avalanche control work for their patrons, this does not extend to the back country.
"Time is required for the snowpack to settle and stabilise."
Yesterday, Mt Hutt, Aoraki/Mt Cook, Ohau, Two Thumb Range, Wānaka and Mt Aspiring all had a "considerable" rating.
The three-day storm this week brought significant snowfall to alpine regions throughout the mid to lower South Island, in particular to South Canterbury, and the Mackenzie Country and Southern Lakes, Mr Daisley said.
"A considerable rating requires careful snowpack evaluation, cautious route finding and conservative decision-making."
If you had plans to head to the back country, it was essential to check the avalanche advisory for the most up-to-date information and follow the guidance, Mr Daisley said.
"You need to get the training and the gear too before venturing out."
