An avalanche warning is currently in place on Aoraki/Mt Cook.
Cold and windy conditions in the South Island mean the warning is still in place.
Storm-slab avalanches big enough to kill, injure or bury a person were sighted over the weekend.
Some debris had come down as low as 1200 metres.
There is also an alert for heightened avalanche conditions in high alpine areas at Mt Hutt and the Craigieburn Range.
