Dunedin City councillor Teresa Stevenson will be censured for breaching the code of conduct and standing orders, and asked to make an "appropriate apology" to the council.
In a statement, Mayor Peter Chin said the apology for disclosing confidential information to the Otago Daily Times would have to be to his satisfaction.
A complaint from Cr Fliss Butcher that Cr Stevenson had breached standing orders was investigated by the council's conduct committee earlier this year.
The committee consists of chairwoman Prof Nicola Peart, Mr Chin and deputy mayor Cr Syd Brown.
Its findings were reported to the council during the non-public part of an extraordinary council meeting last month and a decision was made to censure Cr Stevenson and ask for an apology.
Ms Stevenson was alleged to have leaked to the ODT details of a confidential letter about the Awatea St stadium sent to the Government by Mr Chin and Otago Regional Council chairman Stephen Cairns.
Mr Chin would not comment further last night.
Cr Stevenson has previously said she is unable to comment.
