The town has about 185 business premises that could connect, but chamber president Alistair King told the Otago Daily Times yesterday only 18 had taken the opportunity.
The chamber strongly promoted the installation of fibre optic cable in the CBD to provide ultra-fast broadband, and Mr King said it had a target of 50 businesses being connected by the end of November.
Asked if the low uptake was a problem, Mr King said: ''Not really.''
''It's just that we are not getting through the connections that we thought we were going to.''
As a result, the chamber had called for feedback from its members.
''If there are hold-ups, what are the hold-ups?'' Mr King said.
Once information had been gathered, the chamber could then consider how it might ''help the process along''.
Mr King said the lack of suitability of older buildings might be one of the reasons for the slow uptake.
''While they are not old-old, a lot of them aren't 10 years new, so that could be the reason why they are not getting connected.''
The Queenstown District Council's 2014-15 annual plan includes a $250,000 loan to assist with the fibre roll-out.
Chief executive Adam Feeley yesterday confirmed the council set no targets or conditions on the use of the money, ''other than it be used for the purpose for which it was advanced''.
Deputy mayor Lyal Cocks said to call the uptake ''low'' at such an early stage was ''misleading'' and he believed the uptake in Wanaka was higher than nationally.
Cr Cocks said it was never envisaged all businesses would immediately connect but that the majority of businesses would over time, and it would attract new businesses.
''Therefore I do regard this as a good investment.''
Mr King said meeting the 50-business target would be cause for celebration.
''It's about, hey look, we've invested these funds and a lot of us have chucked in huge amounts of voluntary time. We're looking to celebrate a milestone.''
Mr King said all the cost of getting fibre to buildings is met by Chorus with businesses only having to pay for extending it through their building.
The uptake rate across the whole fibre network in Wanaka, which includes some large residential subdivisions, is about 48%, which Mr King said was a high level when compared with the uptake in other ''fibred up'' towns.
