On arrival on the scene, the boy was found on the beach with bite marks and lacerations to his right calf.
He was treated by NSRI medics and by paramedics on the scene before being transported to hospital in a stable condition. He will be kept in hospital overnight as a normal precaution.
The teenager was surfing at the time of the incident. He turned to catch a wave at the back-line when he saw a fin approaching. He then felt a bump before he was bitten. The boy then caught a wave to the beach where he was met by his father and bystanders who rendered assistance and raised the alarm.
Shark researchers will investigate to determine the species and size of the shark.
