Four people have been arrested and two vehicles impounded following a large tangi in Porirua yesterday.
There were also 27 infringement notices issued and five driver's licences suspended.
The funeral procession related to the Mongrel Mob passed through Porirua suburbs yesterday afternoon, finishing at Whenua Tapu Cemetery in Pukerua Bay.
Kapiti-Mana Police Inspector Nick Thom said the procession involved 200 vehicles and caused some disruption to traffic flows as it moved through Cannons Creek, Waitangirua, Ascot Park and Titahi Bay.
"There was a significant police presence during the procession to ensure public safety," Thom said.
