The seventh edition of the games gets under way later this month, and Toomey described the sight of powder on the slopes around Central Otago as a blessing.
The games deliver an economic boom of about $10million to the region each year, and are on track to do the same this year.
That is what makes that snow so valuable.
"We know the snow always comes but it was getting a bit close," Toomey said.
"This week there has been some proper falls and there is snow on and off as we speak.
"It is early days - things can change within a week in the world of snow fall. But we are hopeful we've got plenty for everything."
The games attract about 750 competitors, and there are 26 events at six venues during more than two weeks of action.
While public interest has spiked with the likes of World Championship gold medallist Zoi Sadowski-Synnott doing so well on the international stage, balancing the books remains a challenge, despite the economic benefit the event delivers for the region.
"From the general public perspective [interest], it's getting better and better. The reason I say that is because of the success of New Zealand athletes. They are becoming better and better known.
"That really helps in terms of people wanting to follow what they do."
Winter Games New Zealand has reached a new broadcasting agreement with Sky Sport this year, which will deliver much more television content to New Zealand fans than previously.
Some of that content will make its way to free-to-air television. That will also help with the events exposure.
"It's [the finances] the hardest part by far. The games went from biennial to annual, which added challenges from a financial perspective.
"And we lost Audi as the naming rights sponsor at the start of this year. In the international market it takes a lot of time to develop the relationships which will deliver significant sponsorship.
"But it is always difficult. You end up relying on community and gaming trusts, local and central Government and a small number of sponsors.
"It would be nicer to have a bigger portfolio of supporters backing the games."
Toomey said it was too early to say how the games would do financially but said "it is always tight".
"We are certainly doing everything within our capabilities to make sure it does [break even]."
The games get under way at Coronet Peak on August 23 with the dramatic night parallel slalom event.
Coronet Peak will also host the alpine ski racing programme.
Cardrona Alpine Resort will host the freestyle skiing and snowboarding World Cups events and the World Para alpine slalom and giant slalom in the second week of the games.
The freeride event will be held at The Remarkables in Queenstown. The international mixed doubles curling tournament is in Naseby and there is ice hockey in Queenstown as well - New Zealand will play Australia in three tests.
The cross-country events will be held at the Snow Farm.
