text: By June 2021, there were 8,061 patched gang members on the Police Gang List, a 4,000 increase from 2016. By November 2022, the number of gang members on the Gang Harm Insight Centre's Gang List had risen to 8,357; the highest number ever recorded in New Zealand history. While National Party police spokesperson Mark Mitchell claimed that the Labour Government's alleged "soft on crime" policies had contributed to a 56% increase in gang membership since 2017, Police Minister Chris Hipkins responded that the Police Gang List included people who had left the gangs or who were associates rather than formal gang members.
  Prominent gangs
  Black Power
  Black Power was formed about 1970 in Wellington as the Black Bulls, and its membership is primarily Māori and Pasifika. It has been involved with various kinds of crime, particularly drug dealing. Its symbol is the clenched fist of the American black power movement, and their colours are blue and black.
  Nomads
  In 1977 the Nomads split from Black Power.
  Head Hunters MC
  The Head Hunters motorcycle club is one of the fastest growing motorcycle clubs in the country. It has chapters in West Auckland, Wellsford, Northland and most recently Wellington and Christchurch after patching over the Epitaph Riders. Its beginning is said to go back to 1967 and has been historically tied to West Auckland although it maintains a presence in Ellerslie through a senior member. In 2011 members of the  motorcycle club in Wellington have patched over to become part of the Head Hunters motorcycle club.
