Police believe that members of this group have strong links to several gangs both in the southern region and Christchurch.
The spokesperson said as the operation is ongoing, they are unable to provide any further information at this stage.
"Methamphetamine continues to cause extreme harm in the community and Police will continue to focus and target those selling and pushing this harm in order to hold those offenders accountable.
"Stopping its distribution will reduce harm not only to those that have already been exposed to the harmful effects of this destructive drug, but those who may never have been exposed to it before."
