Chamber chief executive Anna Mickell said it was actively lobbying the Queenstown Lakes District Council to ramp up public transport so people could get into the town centre efficiently and without delays.
The push comes as the council revealed it wants 1100 new car parks near Queenstown's town centre.
That is almost double the number it wanted last year, when it was looking for developers to build in Boundary and Ballarat Sts.
The increase was something of a U-turn - the council has spent years removing commuter parks from its council-owned car parks and downtown streets.
But infrastructure general manager Peter Hansby said the "community consistently tell us more parking is required" and analysis showed 1100 off-street, covered car parks within easy walking distance of the CBD were needed by 2022.
Ms Mickell said the parking boost would be "awesome for businesses" but pointed out business owners were calling for a parking boost only because public transport was not up to the job.
"What they're really saying, though, is we need to be able to get customers to our places of business efficiently.
"At the moment they see the only efficient way of doing that is the private vehicle, because other ones aren't efficient and reliable enough."
She was ramping up efforts to sort out the resort's public transport.
"Unless we get people out of cars and on to public transport, it will be gridlocked all the time.
"That's why the chamber's spending all their time on public transport now."
In recent months, the council had quietly asked for expressions of interest to build the new parks. That was after scrapping the previous process in December.
Mr Hansby said unlike the initial registration-of-interest process, which identified 252 spaces in Boundary St and 350 in Ballarat St, the latest one requested detailed proposals from developers on other sites.
"Proposals were required to demonstrate how their solutions aligned with the Queenstown town centre master plan and Queenstown-Frankton parking strategy objectives and outcomes, and may include developments on council-owned land or privately owned land."
That tender process finished last week, and the council is now evaluating the bids.
