The judge also ordered forfeiture of any equipment seized by the Ministry of Fisheries in investigating the offences, although the quartet will be able to apply to have it returned.
Mr Humphrey said a fishery patrol spotted the four fishing late in the afternoon of January 25, a Wednesday, and intervened as the men walked up the beach towards McLean's vehicle.
Having hidden a backpack and sack of paua against driftwood on the beach, Puna was the first approached, out of the sight of the others. He ignored directions and was arrested after trying to run-off back to associates. The pack was later found to contain 215 paua.
McLean was stopped with a bag of 39 paua and 3 crayfish, saying he had not been diving but was carrying the bag for his friends.
It was then that Fox and Pitiroi were approached at the water's edge, with bags at their feet. Fox up-ended a bag when he was waist-deep in the sea, discarding its paua contents, while Pitiroi pulled an armful of paua from another bag, ran into the sea and dumped them. The officers believed it was not a suitable habitat for those paua and they would not have survived.
The 300 which were seized from the men were well over the 120 allowed under a customary authorisation permit, which did not include the names of Fox and Puna. Only one paua was a legal size.
Judge Rea told the men their behaviour when the officers appeared was a "fairly full indication you knew the game was up."
