Members of iwi Ngati Kura clamp four cars at Matauri Bay and clamp four cars belonging to students on the beach for a surfing lesson. The group, armed with a portable EFTPOS machine, demanded $800 from Kamo Intermediate principal John Smith and only unclamped the students’ cars after he had paid up.
