"Unfortunately, he has chosen to disregard them. For the sport to function properly, its board must function properly, and ESNZ had to take action to support the other members of the Jumping Board."
Mr Beatson, a riders' representative on the board and former Olympian, said Jumping Board members had not come to an agreement about the levy at its annual meeting, so the ESNZ board had no mandate for the levy.
"The announcement they made has not gone through the board - no one agrees with it," he said. "They are talking about suspending riders if they don't pay these levies and taking their series points off them. They can't ban riders just because they are not paying their levy."
Jumping Board acting chairwoman Kathryn Roberts said the ESNZ board was entitled to set fees and levies "and that was done in consultation with the Jumping Board".
Mr Beatson said costs were already about $200 per horse per show "and what they are doing is packing on another levy".
"It is escalating. If we pay all these levies and everything else it would cost some of these riders another $100 registration."
Mr Bray said, as in any sport, people on boards had to play by the rules or be disqualified. Members could have robust discussion in the board room but once a decision was made it had to be supported.
"Disagreements are fine. That's why we have boards, to ensure a diversity of views.
"But, once a decision has been made, the entire board must support that decision," he said.
