Gang members descended on the Far North en masse over the weekend but police say their visit was almost trouble-free with just one incident.
Sergeant Phil Le Comte, of Kerikeri police, said a large number of Mongrel Mob members attended an unveiling at Whirinaki in South Hokianga.
Members arrived from around the country on Thursday and Friday, staying at Te Tii in the Bay of Islands.
Mr Le Comte said overall the weekend went well thanks to positive liaison between police and gang hierarchy.
The only incident occurred on Friday afternoon when a 46-year-old Tauranga woman walked into a Clark Rd, Kerikeri, home unannounced and proceeded to abuse the occupants.
