A young boy was thrown 15 metres in the air before hitting a metal trailer after he came off his dirt bike on a Northland farm.

The boy was critically injured in the accident, which happened after the bike he was riding hit a concrete lip at a property in Topuni on Sunday.

Auckland Westpac Helicopter Trust media liaison spokesman Lincoln Davies said the boy was airlifted to hospital at 12:30pm.
