The Ministry for Primary Industries (MPI) says its fishery officers have released 650 illegally caught pāua back into the sea after a compliance operation in Taranaki.
MPI said the operation was part of regular compliance checks across the region to make sure people were keeping within the rules "so current and future generations can continue to gather and enjoy this kaimoana".
The team issued eight infringements and nine warnings, and made one arrest.
In addition, several vehicles were seized, one person was arrested after obstructing a fishery officer who was trying to inspect their catch, and six people may face prosecution.
MPI's team manager of fisheries compliance for the western North Island, Andre Espinoza, said during the week-long operation, eight fishery officers interacted with around 180 people during patrols that took place at low tide.
