One vehicle was also seized, and the sole occupant, who allegedly had 44 pāua, was facing court action. A party of three, who had 61, all but three of them undersized, were issued with infringement notices.
"All the pāua gatherers inspected were found to be in breach of the fisheries regulations," Rudsdale said.
"It was also very disappointing to see that all the persons apprehended were from the local area, and should be aware of the need to protect this valuable resource. Pāua are a slow-growing species with poor reproductive ability, and behaviour of this type has a negative impact on the stock.
"In this modern age there is no excuse for not knowing the rules around daily bag and size limits, information that is readily available from the MPI website (www.mpi.govt.nz) or by downloading the free NZ Fishing app."
All the shellfish seized on Saturday were returned to the water, while Rudsdale warned that the ministry would continue to be watching at Ahipara, and elsewhere, to ensure compliance with the regulations. The maximum recreational pāua take is 10 per person per day and the paua must be at least 125mm.
Contravention of the Fisheries Act, which includes pāua poaching, attracts a maximum fine of $250,000 and/or a community-based sentence.
