One of the project’s leaders, Jim Walton, said a group of residents had "fruitful talks" with the Department of Conservation about transferring the building to the community.
They were yet to sort out issues with the department such as continued upkeep and whether there was a need for earthquake strengthening, he said.
The idea was to run it as a community information centre to help people visiting the town.
"The number of visitors seems to be increasing, and it’s not just the summer, it’s the winter too."
Once it was operational, other uses would also be explored.
"We wanted to do something where we wouldn’t have to alter the historic building in any way."
It would have to be volunteer-run, he said.
The town held a public meeting last March on the future of the post office, at which there was "strong support for the idea of transferring the building to the community", Mr Walton said.
Bannockburn local Graeme Stewart was seeking volunteers and creating a committee to run the service if the transfer was successful.
This was "on hold" while discussions with the department took place, he said.
Department of Conservation Central Otago operations manager Mike Tubbs said it had some initial talks with the group.
The building was used for occasional staff accommodation, he said.
The stone post office was built in 1911 to replace the original wooden building, which can still be seen at the rear.
