The teenager, named only as Nathan, was surfing with his father and friends off Koumac village in the north of the archipelago when he fell in the water, the New Caledonian said.
While swimming to recover his board, he was attacked by the shark, which mauled his leg. He was rushed to a hospital but did not survive.
