The council’s review team advised staff of the results on Monday.
The report shows 17 jobs will be axed — but 17 new roles will be created.
Other positions will have a change to reporting lines.
The original proposal suggested up to 20 jobs be disestablished and 13 new positions created.
That plan was changed following the receipt of 78 submissions from staff, the report shows.
Chief executive Clare Hadley thanked staff for their feedback.
It had been "hugely valuable" to have information from "a range of perspectives", she said.
"We recognise that this has been a painful and difficult time for some ... However, we believe that ultimately this structure will better integrate and streamline the wider delivery of our activities and in doing so provide better outcomes for council and the community."
The document also showed seven positions were reviewed; after feedback these jobs would not be cut.
Options for redeployment would be the council’s "first consideration for all staff who are at risk of redundancy".
Public Service Association national secretary Glenn Barclay said when the council began consulting staff about the change process, union representatives were worried about its effect.
"We are pleased to see many of these concerns were taken seriously," he said.
"The PSA is consulting with union members to confirm how the council’s latest announcement will affect them, and if they still have concerns we will raise these with the employer.
"The best outcome is always one where hard-working and skilled staff remain securely employed, and the people of Invercargill continue to enjoy reliably excellent community services."
A council spokeswomen said the chief executive "won’t be commenting on staffing matters".
