The Tauranga City Council proposes to demolish its civic administration building and library in Willow St.
It plans to move its staff into a to-be-developed leased building in the medium term, and rebuild the library as part of an estimated $47m "civic amenity building" in Willow St.
The commissioners have approved the negotiation of lease arrangements for a new administration hub on Devonport Rd.
It will be developed at 90 Devonport Rd, subject to long term plan community feedback and final decision-making.
After development proposals were shortlisted and analysed, the council chose a preferred partner - Willis Bond & Co - for the project, which will allow it to bring together its administration activities in a central location.
Council staff are currently spread across buildings in Willow St, Spring St and Cameron Rd.
Commission chairwoman Anne Tolley said there were nine proposals, three of which were evaluated on location, lease terms, financial impact, building specifications and assessed risk.
