Newman said this morning police raided five addresses across Auckland in Mt Eden, Pakuranga Heights, Mangere East, One Tree Hill and Papakura.
The six face a raft of charges including money laundering, participating in an Organised Criminal Group, manufacturing and supplying methamphetamine and supplying and possession of pseudoehpedrine.
It follows two arrests last week when a 40-year-old man and 28-year-old man were charged with importing and possessing pseudoephedrine.
Newman said more arrests are possible.
He acknowledged the role of Customs in the bust.
""It is our continued work with our partners that is seeing us significantly disrupt these organised crime groups."
Newman said police were not surprised to see the Head Hunters motorcycle gang linked to this type of offending.
"The Head Hunters have absolutely no care or regard for the harm they inflict on families and whanau by manufacturing and supplying methamphetamine. They continue to take advantage of the addictiveness of this drug in order to profit from it," he said.
