Putting the Horse of the Year contract up for tender is standard business practice, says Hawke's Bay Chamber of Commerce chief executive Wayne Walford.
Kevin Hansen has been the show's event manager for 18 years, in which time it has become the biggest equestrian event in the Southern Hemisphere and the region's largest.
His company Event Pro, will continue to manage this year's show but Mr Hansen will move to Australia for other business opportunities, citing "uncertainty" with future shows.
Mr Walford said tendering an existing contract was good governorship and a standard way to determine if an existing contract was at market rates.
"You could call for a tender not because you don't like the contractor, but because you want to make sure you are getting the best option in the market."
