The avalanche near The Remarkables ski area yesterday afternoon was a result of natural circumstances.
A search involving ski patrollers and dogs got underway following the avalanche on the far side of Lake Alta - but no one was caught up in it.
NZ Ski chief executive James Coddington says fresh snow and warm temperatures would've been the main contributors.
"These things certainly occur outside of ski area boundaries on regular occurrences and where it occurred was a very steep part of the terrain."
The avalanche is believed to have been about 80 metres wide and up to 120 metres long.
