Baxendale said It was just a proposal at this stage and no decision had been made, but If adopted the new structure would save between $600k and $700k.
In the proposal released for consultation with staff, the council's external services would be drawn together in two groups.
The citizens and community group was unchanged and a new group combined infrastructure and regulatory and planning services.
The third group was made up of internal enabling and resourcing services and would be headed by a general manager who is also the chief financial officer.
A new directorate with strategic policy and performance functions would be set up to manage functions, including legal services, the office of the chief executive, strategic policy and public information and participation.
Baxendale said the proposed restructure aimed to quicken the pace of the city's recovery and to ensure that the council provided a better service to the people of Christchurch.
"It provides a better balance between General Managers responsible for delivering levels of service to the community and those providing internal enabling support services.
"It will create clear accountability, clarity of leadership, improve the services provided to the community and reduce silos and duplication.
The proposed change would not impact on council services, she said.
The restructure was around a new executive team and group structure.
Not included in the proposal were front-line staff and their immediate team leaders who would continue to report to the organisation's current third-tier managers.
