Wanaka skifield operators say the 2012 season has been a mixed bag, with good visitor numbers but limited snowfalls.
Treble Cone's season had been dogged by an easterly flow which had "quite a negative impact" on visitor numbers some days, general manager Jackie van der Voort said on Monday.
"The cloud has just hung on the mountain Sunday, Monday, Tuesday and it's started to break up a bit on Wednesday and then Thursday, Friday we've had amazing days. This cycle went on for five to six weeks and we've just broken out of it," Ms van der Voort said.
"But when the weather's been good, business has been great."
Numbers were slightly up on the forecast.
The home basin had been largely limited to on-trail skiing.
However, 65cm of new snow across the mountain during the weekend was "a great way for us to step out into the spring".
Treble Cone will close on September 30.
Cross-country skifield Snow Farm attracted lots of new visitors this season and numbers were equal with last year, manager Jo Lynch said.
"It's been a bit lean on snow but the sunshine has meant that it's brought lots of people up."
She hoped the skifield could stay open throughout September but any wind and rain would melt snow.
At Cardrona, numbers were up on 2011, despite a year light on snow.
"We've had lots of blue-sky sunny days," sales and marketing manager Nadia Ellis said.
A top-up of about 20cm of snow during the weekend and more this week would "see us through" until closing day on October 7. Limited facilities would remain open for two weeks after that for an elite training camp.
Across the Cardrona Valley, Snow Park also had "thinner" snow coverage, but the field had still been in "really good shape" overall, marketing manager Kristy Quin said.
Sales of day passes were slightly down on 2011 but more season passes had been sold, putting visitor numbers on par with last year's. A closing date had not been announced.
NZSki chief executive James Coddington said it was far too early to predict how long the ski season for Coronet Peak and the Remarkables would be. Both fields were scheduled to close on October 7 and Mr Coddington said whether that happened would depend entirely on the weather.
There had been less natural snow this year than previous years.
