A councillor who heckled Stan Semenoff claims supporters of the Whangarei mayoral candidate took physical exception to the heckling.
However, Mr Semenoff's supporters say there was no rough stuff, and the heckler - councillor Aaron Edwards - and friends were rude and used inappropriate language when calling out during Mr Semenoff's presentation at a pecha kucha mayoral evening.
A confrontation involving Cr Edwards, a friend, and supporters of Mr Semenoff flared at the end of the mayoral Pecha Kucha event at Forum North on Wednesday.
Who did what to whom is not entirely clear, but a friend of Mr Edwards claimed to have been barged.
However, Jamie Semenoff, from Mr Semenoff's campaign team, said there was no physical confrontation and that Mr Edwards' group had been drinking alcohol and used inappropriate language in the presence of children.
