"They dump stuff anywhere they choose. It's like they just come down here and throw their rubbish out of their cars and don't care."
He said the dump was set up by the sand dunes overlooking the beach to help strengthen the dunes, not fill them with toxic rubbish.
A council development committee is due to discuss the recommended closure.
Recommendations to the council will include that the greenwaste site be closed on January 1, 2017 and the importation of greenwaste for dune stabilisation be approved.
Mr Denton said the reasons would include:
¦Resource consent conditions will no longer be breached by excessive dumping of greenwaste, while still providing for ongoing dune stabilisation.
¦Prevention of sand hazards (erosion and reported burial of buildings ) which happened at Patea Beach in the 1950s and 1980s.
