High Court Judge Justice Daniel Goundar has found John Nikolic guilty of all his charges.
All three assessors had also found John Nikolic guilty for all charges laid against him.
Nikolic is charged with two counts of possession of illicit drugs, one count of possession of arms and ammunition without a licence and two counts of unlawful importation of illicit drugs.
Nikolic had imported 12.9 kilograms of cocaine and 34.4 grams of methamphetamine with an estimated value of between $20 million to $30 million.
He also failed to declare that he had in his possession two pistols with 112 rounds of live ammunition.
His wife Yvette Nikolic was acquitted of the same charges earlier this month.
Assistant DPP Lee Burney has told court he will consult the Government Chemist on how to safely dispose of the drugs.
The proceedings on the seizure of the yacht will be before the Suva High Court at 10 am tomorrow.
The case has been adjourned to the 8th of next month for sentencing.
