Contestants will be trying to outdo one another with their "cross-mountain" skills in the three categories of big mountain session riding, a banked slalom race run, and the big air finale on Sunday.
"We haven't held a big air competition up here for a while," Treble Cone spokesman Antony Hansen said"It was a great day out for locals in the past, so we thought we'd better resurrect the comp," he said.
The competition's three events are being held in different locations at Treble Cone, near Wanaka.
The big mountain and banked slalom qualifications take place in the Saddle Basin's Superpipe and Shooter on Saturday, while a custom-built launch site halfway down the Main Basin's Big Skite run will host the big air comp on Sunday.
Four qualifiers will progress from Saturday's big mountain and banked slalom to contest the finals on Sunday, Mr Hansen said.
A prizegiving to crown the "Triple Comp King and Queen of the Mountain" will be held on Treble Cone's sun deck after the big air event on Sunday afternoon.
