When people with different beliefs and outlooks on life intimidated others and made them feel vulnerable, society needed to take a stand, he said.
Mr Mitchell raised the issue with Western Bay's police area commander Inspector Clifford Paxton at a council meeting in April.
The audio record of the meeting showed Mr Mitchell saying he wanted to turn the issue into a positive, by giving police the powers to "disincentivise" gang members being antisocial and intimidating people.
Mr Paxton responded that the police had to remain impartial. It was something that had to be discussed by the community and it was up to the council to bring those views together.
City vision committee deputy chairman Cr Matt Cowley told the Bay of Plenty Times the issue had been put into "dormant mode", unless there was a significant community demand for a bylaw.
The council was looking at what impact the bans have had elsewhere. "If they had a big impact, then we would consider it."
His recollection was of police saying that gang patches were no more and no less an issue in Tauranga than in other communities. Police's key priorities revolved around the supply of alcohol and psychoactive substances.
