Negotiations are under way between Trustpower, a local developer and owners of the former Bay of Plenty Times building to construct a purpose-built three-storey office building on the site.
Demolition of the Durham St building is well advanced, with the internal structure of the old offices being gutted and part of the roof also removed.
The time frame for completion of the demolition work is unknown.
Trustpower's communications manager, Graeme Purches, said until all the "i's have been dotted and the t's crossed" it was not a done deal, but all the parties were hopeful of being able to reach an agreement during the next few weeks.
Mr Purches said he could confirm Trustpower was exclusively looking at the Durham St site to build its new Tauranga-based headquarters after eliminating two to three other sites for various reasons but he would not be drawn on the other sites that had been considered.
