Police have arrested three people and seized several vehicles in Tāmaki Makaurau/Auckland on Saturday, as a gang-related tangi procession moved through parts of the city.
Members of the Head Hunters and other gangs were paying respects to Charles Anthony Pongi, 32, who died in early August after he was shot at a Point England park.
Earlier in the day, dozens of mourners had gathered to hold a funeral service at Tipene Funerals Ōnehunga.
Afterwards, members of the Head Hunters, King Cobras, and Hells Angels were seen entering the Manukau Memorial Gardens.
Tāmaki Makaurau assistant commissioner Sam Hoyle said in a statement Friday that police would have an increased presence in parts of the city during the weekend "to monitor gang movements relating to a funeral taking place".
"While we understand people need to grieve, this should be done without putting the wider community's safety at risk," he said.
Extra officers have been deployed on Auckland's roads, in Ellerslie, Ōnehunga, Papatoetoe, and also around licensed premises, such as bars.
"It is the family's wishes that everyone pays their respects peacefully.
"Our expectations are that everyone attending will abide by the rules."
Newshub spotted 30-40 police cars on standby at the entrance to the cemetery on Puhinui Road, with tow trucks nearby.
Pongi's death sparked a massive police homicide investigation, for which police are still carrying out "enforcement activity", said Asst Cmmr Hoyle.
"Police will also be working with other parties on long-term solutions required around any tensions between gangs."
