A High Court jury found Naufahu guilty in October of money laundering and conspiring to supply the class B drug pseudoephedrine.
He was sentenced to 10 years imprisonment by Justice Graham Lang in the High Court in Auckland today.
The public gallery was filled with supporters, including Naufahu's wife.
Naufahu, president of the gang's New Zealand chapter, was arrested in 2019 after a large scale police operation.
He was found guilty last year of money laundering and conspiring to supply pseudoephedrine.
