A Mount Maunganui fisherman was shocked to find several large bags of crayfish dumped at Te Maunga Transfer Station recently.
Sam Toner said a friend, who is not a fisherman, saw the crayfish on November 4 and took a photo.
"He's not a fisherman himself but thought it was curious so took a photo and showed me," Toner said.
"He said as well as what is in the photo there were some reasonably big, clear plastic bags full. I flicked [the photo] off to MPI and they've been pretty responsive, they're looking into it."
Earlier this year, Fisheries New Zealand announced changes to the recreational fishing rules for rock lobster in the Hauraki Gulf/Bay of Plenty rock lobster fisheries from July 1.
