Racing NSW's chief vet has identified issues with More Joyous that will be tabled at the stewards inquiry into the dispute between the mare's owner John Singleton and trainer Gai Waterhouse.

Acting on advice that the horse was not well, Racing NSW chief executive Peter V'Landys said the authority's chief vet was sent to examine More Joyous at Singleton's property in the Hunter Valley on Thursday.

The health of the horse is under question after Singleton accused Waterhouse of divulging information to her bookmaker son Tom on the horse's condition which he was not privy to in the lead-up to the All Aged Stakes at Randwick last Saturday.

Tom Waterhouse allegedly spoke to friends about the horse, including rugby league immortal Andrew Johns and former jockey Allan Robinson, and the information was passed onto Singleton who has since cut ties with the Waterhouse family.

More Joyous is at the centre of a stewards inquiry that will seek an explanation from Gai Waterhouse as to why the horse was treated with antibiotics before the race and why it was not reported.

V'Landys said the chief vet, who had already spent an hour examining the horse after the race on Saturday, was sent to inspect the horse again to make an assessment on her health.

"We act on advice and the advice that we should go up to see this horse was strong," he said.

"There are matters with the horse which would be inappropriate for me to say right now but will be presented at the stewards inquiry on Monday."

V'Landys was giving little more information away in a bid to ensure Monday's meeting presents a neutral environment in which Gai Waterhouse can present her case.

"The stewards will seek an explanation from Waterhouse about why she didn't report the condition of the horse and why she treated it with antibiotics," V'Landys said.

"At the initial inquiry she said she didn't think it was significant enough to be referred to the stewards, so she will be given the opportunity to present her case and be given all due process for the situation."

He added the chief vet's full report would be presented at the meeting.

V'Landys was speaking just 24 hours after he denied requests for Monday's inquiry to be televised.

"We don't believe that it would provide the necessary forum for the people involved getting procedural fairness, natural justice and due process," he said.

"We don't want any distractions. It's a very high-profile and serious case and we want to make sure all parties are given every opportunity to present their cases.

"It is a normal stewards inquiry and it's not appropriate for it to be filmed."

He did however welcome as many non-broadcast media outlets to attend the meeting in keeping with Racing NSW transparency ethos.

"We've always opened it up to the media. We want the public to have full confidence," he said.
