Remarkables and Coronet Peak have both seen 60cm-66cm of powder in the past few days, and Coronet Ski area manager Hamish McCrostie said it had brought many people up to the slopes.
Mr McCrostie said it was too early to tell whether the skifield would stay open longer than usual this season, but he was not ruling it out.
"We will make that call at the time but with the Rugby World Cup, it would be something to think about."
Coronet Peak saw its worst start to winter since artificial snow-making began in 1991, opening four weeks later than usual. Visitors for the Winter Festival in June were disappointed there was no snow on the mountains.
After a frustrating start for skifields, there is a possibility numbers could be made up by taking the season through to October.
NZ Ski chief executive James Coddington said October was still a long way off and right now, he was pleased to get the extra snow in August.
"It is far too early to make calls like that. As we know, weather can change, things can change and a lot can happen in a week.
"We are very excited the snow has come and it is going to set us up beautifully through to September."
Mr Coddington said the Rugby World Cup would certainly come into calculations.
"It would be fantastic if we had this amount of snow in October ... and it'd be a real windfall for the skifields."
Remarkables ski area manager Ross Lawrence said if the snow remained at the end of September and people were keen to get up the mountain, he would support an extended ski season.
Since Sunday night's snowfall, The Remarkables' two car-parks had been full and the slopes packed, he said.
Mr Lawrence said the cost of the skifield's July start had been difficult to make up and an extended season would certainly help loosen things up.
"It is difficult to make up and we'd certainly like to see more people come up here.""The only thing that will influence that is patronage and snowfall."
• Wanaka's four skifields have each received at least 20cm of fresh snow this week, creating powder conditions for snow sports enthusiasts.
The snow base at Treble Cone is between 35cm (at the base building) and 140cm (in the saddle basin), while Cardrona Alpine Resort has a base of between 120cm and 150cm.
Cardrona sales and marketing manager Nadia Ellis yesterday said it was "entirely possible" the skifield could remain open beyond the scheduled season closure of October 2 "if demand and snow justified it".
"But we have, in the past, run out of customers before we've run out of snow. It comes down to adequate demand to make it financially viable," Ms Ellis said.
With rugby visitors, the demand might be there, she said.
Cardrona had experienced its busiest week of the season before the snowstorm struck, and hoped with fine weather forecast this coming week the visitors would return.
"When weather is bad, it does put visitor numbers down.
Not everyone is an enthusiast prepared to brave winter conditions to get fresh powder ... but with fresh snow and fine weather, people always come out in their droves," Ms Ellis said.
Treble Cone reported record numbers during the school holidays after a delayed start to the season.
General manager Jackie Van Der Voort is relishing the conditions and believes they have re-energised people.
However, it was unlikely the ski area would extend its season beyond October 2, because visitor numbers usually dropped and staying open was not financially viable, she said.
