Comancheros boss Pasilika Naufahu has been jailed for 10 years over money laundering and conspiracy to supply a Class B drug.
Justice Graham Lang sentenced him today in the High Court at Auckland, saying he was president of the gang and as such was in a position of influence.
Naufahu was arrested as a part of a covert police investigation called Operation Nova that targeted the Comanchero Motorcycle Club.
More than 80 police officers were involved in the raids, which led to about $4 million of assets being seized, including firearms and several luxury vehicles such as a Rolls-Royce Wraith and gold-plated Harley-Davidson motorcycles.
Justice Lang detailed how Naufahu's family had moved to Australia when he was only 1, and they struggled under financial hardship.
Mansfield said Naufahu is looked to as a leader and has never shied away from admitting he his role as president of the Comancheros.
After a lengthy and high-profile jury trial last year, Naufahu was found guilty of two money-laundering charges - one in respect of a Ford Ranger and the other a $102,075 Bentley.
He was also found guilty, alongside patched Comanchero Connor Clausen, of conspiring to supply the Class B drug pseudoephedrine in September 2018.
He had admitted participating in an organised criminal group and nine money laundering charges which came from purchasing a swag of expensive vehicles.
There were four Range Rovers - with price tags of $175,000, $255,000, $218,000 and $280,000 - a $200,000 Mercedes-Benz, a Lamborghini for $285,000, and two Rolls-Royces which cost $364,000 and $595,000.
