Summer snowfall has delayed Cardrona's summer opening originally scheduled for this Friday.
So far today there has been 20cm of snow fall at the Otago ski field, with more expected to fall.
The mountain's summer activities include mountain biking and mountain carting.
Close by heavy rain is causing Wanaka's lake levels to rise.
In preparation for further flooding Wanaka residents have been given access to sandbags.
Many public toilet lots, parks and walking tracks have been closed as a result.
The heavy rain in Wanaka is due to continue today and into tomorrow according to MetService.
