Two boys who were buried after a sand dune collapsed on a Great Barrier Island beach were reportedly digging tunnels in the sand during a family picnic.
One of the boys, aged 14, was found with his legs sticking out from the sand and was pulled out with the help of a vehicle, Stuff reported.
The other, a 12-year-old, was completely buried and was not breathing by the time he was extracted, the report said.
The two boys remained in a critical condition in Starship Hospital, a Te Whatu Ora spokesperson said today.
Emergency services were called to Medlands Beach around 4.30pm yesterday afternoon. Beachgoers and emergency services, including staff from two rescue helicopters, scrambled to dig the boys out. They were airlifted to Starship.
