Six people have been arrested following raids in Whakatāne, Tauranga, Waikato and Auckland.
The simultaneous search warrants were executed yesterday and were the second phase of an operation targeting organised crime which originated from the arrest of a man for significant methamphetamine offences in February.
More than 70 Police staff, including the Asset Recovery Units from Tauranga, Waikato and Auckland were involved in the operation.
In excess of $1.5 million in cash was seized along with six high-end vehicles and one high-end motorcycle.
Two firearms, a cannabis grow room, cannabis and methamphetamine were also found and seized from an address in Whakatāne.
The six people, both men and women, appeared in the Tauranga District Court yesterday and faced a variety of charges including money laundering, fraud, accessory to the sale or supply of methamphetamine, supply of methamphetamine and the cultivation and supply of cannabis.
They have been remanded to appear in court at a later date.
Acting Area Commander Eastern Bay of Plenty Inspector Phil Gillbanks said: "These people have attempted to increase their own personal wealth and social status through the supply of narcotics, offending that contributes greatly to the misery and social harm of others.
"Through the dedicated work of investigators, police have successfully been able to seize and remove these ill-gotten status symbols of perceived success."
"Profits are what drives organised crime, therefore we will continue to target this motivation for people to become involved in such crime."
