The Navy seized almost five tonnes of cocaine, believed headed for Australia, from a fishing vessel near French Polynesia last month.
The United Nations has said in recent years that organised crime groups trafficking cocaine and methamphetamine have expanded their presence in the Pacific.
Large amounts of drugs are transported from North and South America for Australian and New Zealand markets, according to the UN.
French Polynesia lies along these maritime routes and is itself affected by significant methamphetamine use.
Its small population of 280,000, however, spares it from being a prime target for large-scale drug trafficking.
