Auckland Council is embarking on a major re-organisation, 18 months after being created in the super city reforms.
The merger of eight local bodies to form Auckland Council was one of the country's biggest organisational shake-ups.
Restructuring and hundreds of job losses occurred, mostly in management.
The focus will now shift mostly to the council's frontline work.
The Transformation Project could take a year and a half and aims to provide better service as well as being more cost-efficient.
Public sector union PSA, which represents several thousand council staff, says its input has been aimed at enabling the council to do more, rather than cut staff.
A council spokesman says the project is in its early stages, working out what resources it needs.
