The budget for the Durham St upgrade has blown out by at least $1.2 million.
The Bay of Plenty Times, however, understands the $1.2m is only part of the expected cost increase for the streetscaping project, which started at $6.1m.
Tauranga City Council's finance committee is due to receive a report on the project's financial state on Tuesday next week, with a report on the progress of all streetscaping projects going to the projects committee at a later date.
The Bay of Plenty Times has sought more information from the council about the increased costs for Durham St and reasons for them.
