With a business degree in event management, Andrew Hansen, was the North Island operations manger for Hirequip Events.
Living in motels, he managed events throughout the North Island, but the biggest was the Horse of the Year Show.

He is now operations manager for Eventpro, which also manages other equestrian and sporting events.
"He runs things now - I'm just the boy," his father told Hawke's Bay Today.
