Seven gang members and associates have appeared in the Gisborne District Court after being arrested at and near a funeral procession just short of Nuhaka.
Those arrested face a number of charges including unlawful assembly and possession of offensive weapons.
One of those arrested, a 21-year-old man, was also charged with possession of cannabis for supply, and unlawful possession of a firearm and ammunition, following inquiries made after the vehicle stop.
A police spokeswoman said a police presence was in place in the Wairoa / Gisborne area on Wednesday morning in order to monitor the procession.
"At around 9am as the gang members were travelling north, police became aware that a number of people from another gang had congregated in Opoutama Rd, Nuhaka.
