Six Nomad gang members have been arrested in Patea on charges which include aggravated robbery and participating in an organised criminal group.
The men, aged between 19 and 40, were arrested between 17 March and 5 May in a police operation targeting unlawful conduct by Nomad gang members.
The investigations involved members of the Armed Offenders Squad and CIB, and included a number of search warrants.
In a statement, South Taranaki response manager senior sergeant Andrew Russ said the warrants were an example of the ongoing work being carried out across New Zealand targeting illegal activity by gang members and their associates as part of Operation Cobalt.
"Our aim is on reducing the prevalence of this sort of behaviour and those who are choosing to engage themselves in this type of activity should expect to come to our attention," he said.
The men are due to appear in Hawera District Court on 16 and 26 May on charges including aggravated robbery and participating in an organised criminal group.
