Waitangi Regional Park is one of Hawke's Bay's most significant foreshores, but for some people it's become a place to dump rubbish.
About 100 people helped rectify that over the weekend, taking part in a voluntary clean-up.
Taradale High School was one of many community groups contributing. Principal Stephen Hensman said plastic was a particularly insidious form of waste.
"There are a lot of native birds that nest along here and live along here," he said.
"What collects here in the foreshore tends to go back out to sea. The fish eventually eat the particles, birds eventually eat the fish and we eventually eat the fish. We are consuming plastics."
