Fonua, 24, was one of a dozen people arrested inmid-April after more than 80 police officers raided several Auckland properties as part of Operation Nova - a year-long police investigation into the Comancheros gang.
Those arrested face a raft of charges relating to organised crime, money laundering and drug supply.
The raids saw some $4 million in assets seized by police, including firearms and several luxury vehicles such as a Rolls-Royce Wraith and gold-plated Harley Davidson motorcycles.
