Adam Hall (20), of Outram, and Jossi Wells (18), of Wanaka, are the organisation's joint overall athletes of the year.
Hall also collected the award for the New Zealand Snow Sports adaptive skier of the year, while Wells won the New Zealand Snow Sports Free Skier of the year.
The acknowledgments by the snow sports industry cap a year of success around the world for both athletes.
Hall is also ranked seventh in Giant Slalom (GS), and is in the top 20 in Super GS and Super Combined.
He returned home from overseas earlier this year with seven gold medals from the North American Cup series, a gold and two silvers in the World Cup circuit and gold at the Wells Fargo World Invitational, Winter Park.
Wells was named 2008 World Superpipe Champion, and became the first New Zealander to pick up silver at the world's biggest freeski event, the Winter X Games.
Both athletes were also acknowledged at the Otago Sportsperson of the Year Awards in May.
Wells won the Otago Daily Times Class Act Junior Sportsperson of the Year award for the third successive year.
Hall was nominated as one of three finalists in the same category (the other finalist was Alexandra mountainbiker Matt Scoles).
Wells has said it is his life goal to win X Games gold in both slopestyle and superpipe, while Hall is totally focused on winning a gold medal at the Vancouver Winter Olympics in 2010.
