Running between the launch station building and the State Highway 6 bridge, the three parallel lanes could take up to six people at a time.
Riders could reach speeds of up to 62kmh.
Designed to provide an alternative activity for the 90% of people who visit, but do not jump each year, the venture is especially targeted at groups, families and the emerging Asian market.
The proposal yesterday came before commissioners Sally Middleton and David Clarke at the Crowne Plaza in Queenstown, to determine whether the resource consent application should be publicly notified.
Involved in the ride are three lines running 140m to a tower construction on the side of the gorge, from where riders would rotate 180deg and return back to the canvas-roofed, steel-framed launch station.
AJ Hackett counsel Graeme Todd said Lakes Environmental's grounds that the consent should be notified due to potential visual impact were unfounded. Any visual impacts would be minor considering the existing recreational character of the landscape.
"It's a highly modified environment that's frequented by 350,000 visitors a year."
Landscape architect Ben Espie quoted a Lakes Environmental landscape issues report which stated visual effects would only be experienced from areas in which "observers have already been immersed in a busy, noisy and visually complex activity".
Lakes Environmental planner Annemarie Robertson, however, said she would still "stand behind" her overall recommendation.
As part of an agreement on the proposal, AJ Hackett has agreed to remove a bungy trampoline on the site, and undertake and maintain native plantings.
The commissioners reserved their decision.
