The Christchurch City Council is cutting three executive jobs, halving its number of general managers.
In a statement on Monday, chief executive Dawn Baxendale said the council needed to change the way it works.
"The roles of the general managers of strategy and transformation, consenting and compliance, city services, corporate services, and finance and commercial are disestablished," the council said in a statement.
"Two of these roles, finance, and corporate services, have been vacant for a number of months."
Confirmation of job cuts comes after Baxendale said in December there would be an executive restructure.
"We need an organisational structure that will allow us to respond to the challenges we face as an organisation at this stage of the city's regeneration," she said.
The cuts were expected to save between $600,000 and $700,000 per year. Baxendale said in December the new structure would provide better balance.
"We are creating clear accountability, clarity of leadership, improving the services provided to the community, and reducing silos and duplication."
Moving forward the new structure would listen to the community's needs, Baxendale said.
"This will mean right sizing in 2021 what is right for this council."
