The Papakura District Council stripped a councillor of his committee responsibilities in a special meeting last night.
The council voted to remove Ross Vickery after he breached the confidentiality of a meeting held in committee last week by speaking to reporters.
The council had been discussing an internal report aboutalleged irregularities by some councillors claiming meeting allowances.
Deputy mayor Vivienne Pollock called last night's meeting because "I don't think it was befitting at all for him to come out of a confidential meeting and speak to the press."
Mr Vickery, absent last night because of a business appointment, told the Herald he had no regrets and was now considering running for the mayoralty.
"I would like to clean out this council on behalf of our ratepayers."
Mr Vickery said he would not resign from the council. He would carry on even though he had "lost almost everything I had" in a long-running battle with other councillors.
"I'm not going to give in. No way."
Mayor David Hawkins said the council had shown quite clearly that Mr Vickery had not met the standards of behaviour required for public office.
He was unconcerned by Mr Vickery's mayoral bid.
"Well, good luck to him ... But if the people of Papakura want a clown, then he might have a good show of winning.
"If you're going to be mayor you've got to stand up and face the music. He didn't turn up tonight," said Mr Hawkins.
Yesterday's special meeting also raised concerns about the accuracy of recent reports by the Herald and community newspapers.
It voted to complain to the press council about the Herald's reportage and to restrict the media's access to meeting agendas until the day immediately before a council meeting.
Mr Hawkins said he was unhappy that the Herald had not replied to claims by the council that the story containing Mr Vickery's remarks was incorrect.
"The Herald are scurrying away like the gutless rats they are."
