Cr Gerry Eckhoff has complained, apparently over matters linked to talks held between Mr Woodhead and Dunedin Mayor Dave Cull over the future of Dunedin's harbourside.
Otago regional councillors will at 8.30am today attend an extraordinary meeting of the council to discuss how to deal with the "code of conduct hearing process''.
The meeting agenda states council chief executive Peter Bodeker had received a complaint under the council's code of conduct, and a tabled report recommends a process for hearing the complaint.
But the code was "silent on the process of responding to alleged breaches''.
The complaint was received on November 11 last year.
The process would be considered at today's meeting, with the "substantive matter'' proposed to be heard by council on February 10.
This report does not outline details of the complaint but refers to "harbourside issues''.
A story published in the Otago Daily Times on November 5 last year said a "fresh push to develop Dunedin's harbourside'' had triggered a "war of words'' between Mr Woodhead and Cr Eckhoff.
Mr Woodhead and Mr Cull had previously confirmed discussions had begun between them to identify a way forward for development in the area south of the Steamer Basin.
The ODT story said most regional councillors had welcomed the initiative, but Cr Eckhoff had contacted the ODT to criticise the ORC's approach and to accuse Mr Woodhead of overstepping his authority.
Cr Eckhoff said Mr Woodhead had no mandate to initiate talks without first seeking the endorsement of regional councillors, and he was the ORC chairman, not the "president''.
Mr Woodhead defended his role and said any decisions would be made by regional councillors and matters would be referred back to them.
He did not find it "particularly professional or enjoyable normal practice'' to have conversations with "fellow councillors'' through the media, Mr Woodhead said.
The ORC report suggested councillors at the February 10 meeting would consider if the complaint was established, and any potential consequences.
Possible consequences included taking no action, requiring or requesting an apology, censure, or defining Cr Woodhead's "mandate, if any, for harbourside issues'', the report said.
