Statistics from the July 1, 2012, to June 30, 2013, annual report, presented at the bureau's annual meeting last week, show it was the first time the number of inquiries/services had dropped in recent years.
The latest figure is down from 4895 the previous year.
It was thought the drop was due to a growing number of people accessing information through the bureau's website, or calls being diverted to a neighbouring bureau when the phone line was busy, the report said.
October was the busiest month, with 492 inquires.
The reports said spring always heralded a new wave of international visitors looking to live and work in Queenstown.
Funding was obtained from sources such as the Central Lakes Trust, the Community Trust of Southland and the Community Organisations Grants Scheme.
