"My concern is for the health and safety of every member of the public, including mountain bikers," Trent Yeo, managing director of Ziptrek Ecotours, said.
More than 40 forest users attended the meeting at the Queenstown Lakes District Council (QLDC) chambers to discuss plans to expand existing mountain-bike tracks and provide gondola lift access in the Ben Lomond reserve this summer.
Mr Yeo said he was concerned for public safety at track "intersections", which could be accessed by walkers, cyclists and users of his zipline network.
"We have an ethical choice to make when we are called for first aid ... I don't want us to get into a situation where our resources are used for the bike park," he said.
Chaired by QLDC district forester Briana O'Brien, the meeting covered signage, track extension, health and safety, harvesting, fire and evacuation points.
Ms O'Brien said the first season of operations was being treated as a "trial period" and, therefore, no emergency care would be on site in the first year.
Emergency response co-ordination was being planned with St John Wakatipu and Queenstown police and evacuation points would be marked on signs and maps.
Riders would be advised to ride in pairs, with mobile phones, she said.
Mr Yeo said improved signage would be "positive" but would not eliminate the risk of collision.
Lance Brown, a regular user of the existing bike trails, said the council needed to look at providing a forest patrol.
QLDC parks manager Gordon Bailey said if the "need for a patrol or ranger" became apparent, the situation would be assessed at the annual QLDC budget meeting in July 2011.
