Four men are facing charges, after an alleged operation where a group of divers overfished paua from remote areas of Wellington, and sold it on the black market.
MPI says the group were diving in isolated areas around Wellington's south coast that were only accessibly with specially equipped 4x4 vehicles.
MPI team manager (fisheries) for the eastern and lower North Island, Mike Green, said the operation came to a head when fishery officers went to an area on the capital's south coast to inspect the activities of two divers.
It was during that inspection that officers discovered the pair had more than 600 paua. That's 30 times the daily limit for two people.
The two vehicles and dive gear used that day were immediately seized.
