Authorities have busted what they say is an Iranian organised crime ring operating in Auckland.
Police have been working with Customs staff for two months on the operation targeting the alleged criminal syndicate.
With the assistance of Armed Offenders Squad officers, they raided two central Auckland properties early on Thursday morning.
Acting Detective Senior Sergeant Bruce Howard says they started the operation after arresting a man trying to bring about 2kg of methamphetamine through Auckland Airport.
Mr Howard says they have also picked up the person they believe arranged that shipment, along with two others.
Two Iranian nationals living in Auckland, aged 31 and 42, will face a range of charges relating to importing and supplying methamphetamine. The pair also face charges of being involved in an organised criminal group.
A third man, a 34-year-old New Zealander associated to the King Cobra Gang, is charged with possession of methamphetamine for supply.
