Whanganui residents are disgusted with the destruction that was left around Castlecliff's Duncan Pavilion on Sunday morning.
Resident Robert Haworth said he was shocked to see the area covered with broken beer bottles and rubbish.
"The danger is the broken bottles and glass that is mixed into sand on the carpark and leading onto the beach."
His Facebook post sparked attention from other residents appalled at the irresponsible behaviour.
Bruce Tonkin said: "This happens far too often. People who do this have no respect for themselves for a start or the rest of us."
