Kaipara iwi are "disappointed" and "disgusted" after two people were caught with 138 snapper – nearly seven times the daily limit – over the weekend.
Fishery officers patrolling the Kaipara Harbour found 138 snapper aboard a recreational vessel at the Ruawai boat ramp with two people on board.
The daily catch limit per person for snapper is 10, with a minimum length of 27cm in the West Coast area where they were fishing.
Ministry for Primary Industries regional compliance manager Phil Tasker said all the fish were seized along with the boat they were fishing from.
"Everyone is entitled to catch a feed – but we would encourage all fishers to understand the rules. Don't take a gamble as you risk infringement tickets or potentially appearing before the courts," Tasker said.
