The Winter Games freeski slopestyle champions are United States pair Gus Kenworthy (19) and Devin Logan (19), in a repeat result from halfpipe competition earlier this week.
Kenworthy is now eyeing a three-peat in the big air competition at Cardrona tomorrow.
"It feels good. Fingers crossed it will go the same way in the big air on Saturday," Kenworthy said yesterday.
Home-town favourite Jossi Wells (21), of Wanaka, was second, also repeating his result from Wednesday's halfpipe.
The slopestyle competition and Snow Park course this week has been attracting media attention because the discipline has been accepted into the Winter Olympics programme from 2014.
Slopestyle skiing is all about art and aerial expression and Kenworthy did not disappoint, accomplishing a technical flow of tricks including left double 1260 mute grab, a switch rightside 1080 tail grab and a switch 540 with a rodeo 540 out to earn 87.85 points in his first run of the final.
He crashed in his second run.
Wells, the 2010 overall freeski world champion, crashed in his first run in the final but some novel tricks in his second run earned 83 points to secure him second place.
He then had to wait anxiously to see whether any other athlete could push him down the ranks, but none did.
Young slopestyle specialist Nicholas Goepper (17), of United States, was third.
New Zealand entered 12 men but with Wanaka's Byron Wells (19) out with an injury, his older brother was the only realistic finalist prospect on the team.
He qualified sixth in a field of 12, whittled down from 41.
"I'm great. I am just stoked. We got some good weather finally and it was nice and sunny for the finals," Wells said.
He praised the course, prepared over several days of snow storms and was looking forward to the big air competition at Cardrona Alpine Resort tomorrow.
Wells has recovered from a serious ankle injury that hampered his training and competition last season but is still managing knee pain that has bothered him for nearly six years.
"My knees are quite sore from flat landings yesterday in the half pipe ... but bring on Saturday and the pain of the big air," Wells said.
There was definitely pressure on the athletes now slopestyle is an Olympic discipline but they were at a level where pressure should be expected and they should be able to deal with it, Wells said.
"The funny thing is I actually feel the pressure more at home, because at home we have everyone watching," he said.
Flying the flag for New Zealand in the nine-strong women's field was Rose Battersby (18), of Taupo.
The women's event did not require qualifying heats and was a straight three-run final.
Logan, ranked sixth in the world, was the favourite and won her second Winter Games gold medal.Kim Lamarre (23), of Canada, was second and Dara Howell (17), of the United States, was third. Battersby finished fourth.
