A Pāpāmoa man walking his dog on the beach this morning was shocked to find hundreds of rusty nails sticking out of the sand.
Kenneth Macpherson said it was clear someone had been burning wooden pallets, and while the fire took care of the wood the steel nails had been left behind and distributed throughout the sand by the tide.
"It was just my normal morning walk with the pup," he said.
"On the way back between the jet ski lane down from the boat ramp, I spotted a bunch of sharp things sticking out of the water."
