NZSki has been given the green light to proceed with a plan that will see the skiable area at The Remarkables increase by 15%.
The Department of Conservation and the Otago Conservation Board approved consents after a four-year planning and research process, Mountain Scene reported today.
The consents also allow NZSki to draw an additional 310,000 cubic metres of water from Lake Alta for snow-making.
The development plan includes a 1.3km chairlift from from the bottom of the two existing car parks at 1600m to almost the top of the mountain at 1900m.
That would increase the skiable area by 15%.
NZSki told Mountain Scene the project would be undertaken over several years as commercial circumstances allowed.
"It's not for this season because we didn't know the consents were going to come through in February," chief executive James Coddington said.
"Even if we did we still couldn't have put in a chairlift before opening in two months' time - it's not realistic."
