An outboard motor, paua and other property were seized by compliance officers.
MPI Wellington and Taranaki district compliance manager Mike Green said while he was very pleased with the work of his compliance staff, he was disappointed to see gathering on this scale and magnitude continuing to take place in and around the Wellington coastline.
"Wellington is well known for its paua and in places there is a good and plentiful supply for all to enjoy.
"The actions of these individuals in this particular case go a long way to ruin that for everyone else. Taking quantities of that size strips an entire area and can take months if not years to recover.
"It is timely to remind everyone that recreational fishing rules have been developed to ensure the sustainability of our fisheries. Taking just enough for a feed, within those limits, allows everyone to enjoy and taste the bounties of our coastline."
Three men will appear in the Porirua District Court on November 11.
