Tauranga City Council says it will announce more details about an independent investigation into the Bella Vista Homes saga next week.
Council communications manager Aimee Driscoll said the scope of the investigation, announced by chief executive Garry Poole on Tuesday, would be limited to the Bella Vista Homes at Lakes Boulevard and Aneta Way.
The investigator - to be an external expert - would be asked to proceed "as quickly as possible".
