Jarome Fonua, 26, appeared before Justice Fitzgerald in the High Court at Auckland this morning.
He was among a dozen people arrested after a series of raids across Auckland last April, which saw police seize $4 million worth of assets, including luxury cars, motorcycles and jewellery.
Fonua pleaded guilty this morning to participating in an organised crime group, money laundering and possession of methamphetamine.
Justice Fitzgerald convicted him and remanded him in custody for sentencing on 23 October.
