Palmerston North, Feilding and Horowhenua gangs have borne the brunt of yesterday's police operation which resulted in 31 arrests across 10 towns and cities and the seizure of $500,000 worth of methamphetamine.
As part of Operation Stamp, more than 100 police officers executed more than 40 search warrants, seizing luxury cars, motorcycles, firearms and drugs.
Detective Superintendent Brett Kane, from the Organised Financial Crime Agency of New Zealand (OFCANZ), today said the operation had dealt a blow to a would-be New Zealand branch of the Australian Rebels Motorcycle Gang.
The arrests included a number of Rebels members.
In Palmerston North, Feilding and the Horowhenua area, 13 people were arrested and more than $100,000 recovered. The records of a Palmerston North finance company are now under investigation as police suspect it of money laundering.
Three people were arrested in Wanganui and Hamilton and more than $10,000 recovered.
In Northland firearms and drugs were recovered while a clandestine lab was discovered in Murupara, about 60km south east of Rotorua, and four people were arrested.
In total, police seized more than $120,000 in cash and 29 vehicles -- including BMWs, Mercedes and Harley Davidson motorcycles -- as well as firearms, gang patches, cannabis and methamphetamine.
"This has disrupted the work of a serious organised criminal network which is peddling the misery of methamphetamine in our communities," Mr Kane said.
"We said we wouldn't be putting the welcome mat out for them, and we will continue to thwart their efforts to set up here."
Police Minister Judith Collins said the operation would have a significant impact on the supply of methamphetamine, or 'P'.
"The number of gangs involved shows they are putting aside their differences and working together in what is a highly lucrative, but evil, drugs franchise," she said.
