Footage captured at Orewa Beach in Auckland, New Zealand, showed a lifesaver and beachgoers trying to drag the predator back into deeper water, only to discover it was dead.
Witnesses on the beach said a group of men was seen kicking the shark in the jaw and laughing as it lay injured, Stuff reported. Horrified beachgoers tried to intervene and stop the group's brutality, but the men became 'exceptionally intimidating', the publication reported.
'Police and (the Department of Conservation) arrived on the scene as other beachgoers attempted to pull the shark back into the water,' the witness said.
'The group of men gave false details to police and joined the larger group.' A police spokesman confirmed they had received reports the animal had been dragged onto the beach and repeatedly kicked.
Lifeguards then tried to drag the shark back into deeper water, but noticed the animal wasn't moving.
Shortly afterwards the shark was washed back onto the shore and confirmed dead.
It's believed a gill net was used to catch the great white shark.
Great white sharks are protected in New Zealand waters under legislation which carries a maximum penalty of a $250,000 fine and six months imprisonment for those who kill the big fish.
