Spectacular images have captured frozen chair lifts at Mt Hutt Ski Area on the first day of winter*.
A helicopter was needed to access the mountain top due to a dump of heavy snow.
Richie Owen, Mt Hutt's sales and marketing coordinator, told 1 NEWS that Mt Hutt is susceptible to "rime events" causing large ice build ups as it's so close to the ocean.
"When we expect a rime event like this we have a storm trooper crew that monitor and remain on the mountain," he says.
"This would include at first light climbing each lift tower with a Yetti stick and bashing the ice off. We cannot move the lift until most of the ice is cleared from the towers and pully sheaths."
Owen says the chilly weather is a good omen for the season ahead.
"This has set us up for an epic start to the season. We anticipate starting the season with all lifts and terrain park offering."
Mt Hutt's ski-season is due to begin next week on Friday, June 11.
*Today marks the meteorological and climatological start of winter in New Zealand.
