A staff Christmas party ended in tears on Saturday with four children taken to hospital after strong winds blew a bouncy castle along the ground.
It's understood that the ASB Bank in Whangarei was holding a staff Christmas function at Heritage Park in Maunu, attended by a number of staff and families.
Northland St John Ambulance boss Tony Devannay said it appeared a gust of wind picked up the bouncy castle and dragged it about 20 metres along the ground.
Three children were on it at the time and another was hit by the equipment as it was blown along.
The four children, aged five and six, were taken to hospital with minor injuries.
A person who was at the event said it had been secured to the ground with electric fence stakes.
