The trail will be officially opened on October 18, following three years of planning, construction and raising $3.4 million. There is about $97,500 still to get.
Mr Budd said the trail network, which was more than 110km, would cement the resort's reputation as a world-class biking destination and had wider benefits.
"It adds another string to our bow in terms of a fully connected, end-to-end trail that we can ride either in whole or in pieces.
"They are all fantastic pieces, but being able to connect them up and going through some new areas that have never been experienced by the public before is really exciting.
"It really does provide something that's pretty special that I don't think is offered anywhere else."
Mr Budd said there was "no question" biking in Queenstown had been a huge growth area, which catered to all levels - from "extreme" bikers to those who enjoyed a leisurely ride.
Along with the Queenstown Trail, other trails and biking activities were set to open in the coming weeks.
Those included the Queenstown Bike Park, the southern hemisphere's only gondola-accessed downhill mountain biking trails, which officially opens tomorrow and the Walter Peak back-country trail, which includes a 45-minute cruise on TSS Earnslaw, set to reopen on October 23.
The 55km one-day ride is the first stage of the Around the Mountains trail being developed as part of the National Cycleways project.
The addition of the Queenstown Trail meant Queenstown would be the top choice for keen cyclists from New Zealand and the world.
"The first market is the one that we all overlook because it's not as sexy. That's the domestic market," Mr Budd said.
Increased flights from Auckland and Wellington and a strong South Island domestic market would encourage more New Zealanders to experience the new trails.
In addition to Australian visitors, he expected interest from Europe, the United Kingdom and the United States - countries which "understand biking" but did not have the opportunity to experience "riding in the mountains, but on the flat".
"I think once the trail opens and we actually get the opportunity to get some people on it, it will really take off.
"Our experience offers something everybody at every level of ability can enjoy.
"I think that's a huge opportunity."
Trails Trust chief executive Kaye Parker believed the community would be "really surprised" at the level of interest in the network from international tourists - particularly those from the Asian markets.
"I've just had a magazine from Hong Kong contact me ... and ask for photos because they want to do a feature.
"We've done no publicity yet, so it's fantastic.
"We should not overlook Asia. Cycling, particularly in China, is huge.
"The fact that I get this call out of the blue from Hong Kong ... I'm beginning to think, heaven's above, we might be in for a ride."
The trail has already been hailed as one of New Zealand's flagship trails and was one of 18 projects earmarked as a "New Zealand Great Ride".
The trail runs alongside rivers, lakes and mountain ranges and connects the Wakatipu Basin, Gibbston, Arrowtown, Lake Hayes, Frankton and Queenstown Bay for the first time.
Cyclists could complete a full multi-day ride or explore parts of the trail, designed to showcase alpine scenery and provide easy access to Queenstown experiences including bungy jumping, jet-boating and wine tasting.
