Three riders have been injured at the annual Ngaroma trail bike event in Waikato.
The region's rescue helicopter headed to the event about 12pm on Sunday after three riders had crashed off their motorbikes in a short space of time.
A 14-year-old Hamilton girl with a head and arm injury and a 48-year-old Tokoroa man with a broken leg were both flown to Waikato Hospital. The other person was taken by road in an ambulance.
The ride starts and finishes at Ngaroma Hall in the Otorohanga District and there is a separate track for children to ride on with supervision.
