Fishery officers have seized a boat that was caught in the Hauraki Gulf with almost five times the legal limit of snapper.
The three men on the boat were caught with 99 snapper between them inside a mussel farm near Kawakawa Bay east of Clevedon on Wednesday, and are likely to face prosecution.
The daily limit in the area is seven snapper per person, or 21 between three men.
The Ministry of Primary Industries (MPI) said one snapper was undersized, and officers also found one undersized kingfish in the catch.
