Flying without a licence can lead to prosecution by the Civil Aviation Authority.
Lamberton said the 1200-member association believed speed flying was affecting the sport's image.
"It's of great concern to us that, while technically it is paragliding, it is not really what paragliding normally involves.
"It's definitely much more high-risk, and that is kind of tainting the sport from our point of view.
"But, it's got an attraction for people.''
Keane worked for Central Machine Hire by day and frequently worked at Lalaland Lounge Bar as a DJ at night.
His manager and ''good friend'' Alex Earll said Keane was one of his ''go-to DJs'' who loved all music from old school to newer hip-hop.
"A really nice guy; really adventurous, really hard working; he loved his action sports.
"I'm going to really miss Jimmy up here.
"He was kind of part of the woodwork.''
Earll said it seemed like Keane never slept.
"He'd be playing music up here all the time and working as a digger in the morning.
"I don't know how he did it.
"He was like 43 going on 28.''
He had also recently become involved in speed flying "quite heavily''.
"He picked it up as a hobby and was going every weekend, pretty much.''
Earll said members of Keane's family were due in Wanaka in the next day or two and, although unconfirmed, he believed a memorial service would be held at the bar.
Central Machine Hire owner Allan Dippie said there was a "sombre'' meeting of Keane's workmates yesterday morning.
"It's a pretty small, tight-knit team.''
Keane had worked for the company for two years, on a variety of projects.
"He was a really nice guy; very popular with staff - very friendly, outgoing.''
Keane's Facebook page records he attended The Taieri High School, the Southern Institute of Technology, and had lived in Queenstown and Sydney.
