The Times-Age counted a pile of 315 paua shells and guts, among a cloud of flies, on the edge of Colombo netball courts' carpark in Masterton yesterday morning, with most ranging from 90 to 100mm in length.
The legal size for normal paua is 125mm, with a daily limit per person of 10, unless fishers have customary authority to catch more or pick up smaller sizes.
Times-Age readers took to Facebook to vent their anger over photos of the pillage, with more than 40,000 viewing the photos.
Charlotte Macdonald-Winiata said this was the reason paua would be gone or illegal to gather before too long. She hoped the culprits got "mad gutsache" from eating the paua.
"Have some respect for the rest of us, only takes losers like you to ruin it for everybody else."
Sandra Blundell said the greed was a disgrace and there would be nothing left for future generations.
Tania Gibbins said it was disgusting how people "take kai from our ocean then dump the shells, you horrible person -- shame on you. And to read they are undersized -- Aue!".
Jac Ward reckoned it might be time for a five-year ban to let paua build up again.
Masterton District Council responded to a call from the Times-Age, cleaning up the mess within an hour.
A council spokesman said they had informed the Ministry of Primary Industries.
