Invercargill Mayor Tim Shadbolt says Environment Southland chairman Ali Timms has damaged her credibility by telephoning him on a regional television talkback show posing as Ruby, a mother of two whose husband had been made redundant from the Tiwai Point aluminum smelter.
"I can't understand why she would do it. She is usually so sensible ... so rational and clear-headed. This was a lapse of judgement," he said.
Acting Environment Southland Chairman Nicol Horrell issued a statement saying councillors had accepted Ms Timms' application for six weeks leave of absence, effective immediately.
"Councillors have unanimously expressed our extreme disapproval of the unacceptable lapse of judgement shown by chairman Ali Timms in taking part in the Invercargill City Council's televised talkback programme under an assumed name last week.
"We expect to hold an extraordinary meeting of council to consider the council's chairmanship in late January," he said.
