Detective Inspector Aaron Pascoe said the investigation into the series of arsons remained ongoing.
However, today's arrests showed the commitment from police to stamp out criminal offending by organised crime groups and to hold them accountable.
"Lives and families are destroyed by methamphetamine and gangs are at the centre of that destruction.
"[The] police and our partners see the hurt methamphetamine causes to individuals on a daily basis," he said.
"All gangs are interested in are the profits so they can lead an outwardly lavish style. They have no interest in the damage left behind by this drug they continue to peddle."
All six men appeared at Manukau District Court this afternoon on a range of charges.
They have been remanded in custody to next appear on November 3.
They each were granted interim name suppression.
