More than 100 North Island police officers executed more than 40 search warrants and arrested 30 people today. More arrests are expected.
The operation exposed what police believe to be an organised and large scale methamphetamine network and produced evidence that gangs are working together to conduct illegal business.
There was also an apparent increased presence of the Australian Rebels gang in New Zealand.
A clan lab was uncovered in Murupara, about 60km south east of Rotorua, and a Palmerston North finance company is under investigation.
"The majority of people involved in producing and dealing methamphetamine are drawing benefits and squeezing the taxpayer dry while make making amounts of money that many people can only dream of," Detective Inspector Chris Bensemann said.
Police today seized 29 vehicles, including BMWs, Mercedes and Harley Davidson motorcycles, and more than $120,000 in cash. They also seized firearms, gang patches, cannabis and methamphetamine.
The warrants were executed in Palmerston North, Feilding, Levin, Foxton, Otaki, Wanganui, Murupara, Hamilton, Auckland and Northland involved police from Central, Bay of Plenty, Waikato, Auckland and Northland.
