New groups, most notably the Comanchero and the Mongols, have
established and, according to police data, gang membership
has increased 50 per cent since 2016.
At the end of August, the national gang register carried the
names of 71 of the 501s.
Police previously said many of the deported gang members were
powerful and influential figures in the Australian
underworld who brought with them professionalism, a new flashy
image and significant international connections.
Earlier this month, Assistant Commissioner Richard Chambers said
there had recently been "a desire by criminal networks to move
more into the South Island and we've seen that with the Mongols
and others down there in Christchurch".
