The Police Minister is applauding officers ' management of a gang tangi in Opotiki

Hundreds of Mongrel Mob members descended on the Bay of Plenty town last week for the funeral of a gang boss.

Police closed public roads for two hours for Whakatane funeral procession.

Minister Ginny Andersen says it's unacceptable people's daily lives were disrupted - but police used the opportunity to enact new legislation.

She says officers arrested gang members, searched their cars, impounded their vehicles and seized their weapons.
