Key Points:

An English trainee doctor has died from his injuries after a "sand boarding" accident last week in the Far North.

Thomas Michael Donaldson died in Auckland City Hospital from the serious head injuries he suffered last Tuesday when he tumbled from his boogie board while surfing down sand dunes opposite Omapere, on the Hokianga Harbour.

Locals told Radio New Zealand the dunes were so steep that if a boogie board dug in, the rider was flung head-over-heels down the slope, with no way to stop the fall.

They said visitors were routinely warned not to go there, after serious accidents in the past.
