The man had another person's ticket, which had expired the previous day and was identified by Treble Cone's newly-installed electronic ticketing system.
He was given a pre-charge warning from police and trespassed from all Queenstown Lakes skifields for two years.
The other fields are Coronet Peak, the Remarkables, Snow Farm, Snow Park and Cardrona.
Constable Mike Johnston, of Wanaka, said the ban was the first of its kind issued under a new collective agreement between Wanaka and Queenstown police and the six skifields in the district.
At a pre-season meeting in June, police and ski industry management decided to impose two-year bans across all the skifields for serious offending, including ticket fraud, violence or theft, Const Johnston said.
Previously, NZSki issued lifetime bans from its own three fields - Coronet Peak, the Remarkables and Mt Hutt in Canterbury - but the company had "come in line" with Wanaka skifields to enforce the two-year district-wide ban.
The new agreement emphasised the "big consequences" of breaking the rules.
"This is just a show of how the ski industry and the police are working together to stamp out this type of offending," Const Johnston said.
"[We're] motivated to get it known internationally that if you come to New Zealand for skiing ... particularly the Lakes district, that these are the rules you play by and you risk a lot by breaking those rules."
Treble Cone general manager Jackie van der Voort said the ski area's new ticketing system had proved its worth by detecting the offender on Saturday.
"It's just very difficult to get away with that [ticket fraud] now," she said.
