The New Zealand Defence Force (NZDF) was part of an international naval coalition that seized NZ$300 million of heroin from traffickers in the Western Indian Ocean.
Working on surveillance information from Royal New Zealand Air Force (RNZAF) aircraft the P-3K2 Orion, crew from Royal Australian Navy frigate HMAS Warramunga intercepted a fishing boat and discovered 915 kg of heroin on Wednesday.
The Orion had tracked the boat, which is believed to be bound for Africa, and stayed in the area while Warramunga's crew inspected it.
The narcotics were found stashed in the hold of the boat.
Two Royal New Zealand Navy sailors who were on exchange on the Australian boat then drove sea boats to transport Warramunga's boarding party and the seized heroin.
