Mr Humphries, speaking at AgQuip on Thursday, said the ban was "ideologically driven" and a "hasty reaction without considering all of the details".

"I didn't join the National party or the Coaltion to implement green policy or minority group policy," he said.

"W'eve been a good government up to this point, but not on this issue."

Mr Humphries joined members of the NSW Greyhound Racing Industry Alliance at AgQuip to speak to the media and visitors about the Greyhound Racing Prohibition Bill 2016.

NSW Greyhound Breeders, Owners and Trainers Association chief executive officer Brenton Scott also spoke.

Debate on the bill is expected to resume in the lower house on Tuesday, after it was introduced into the upper house first last week - a reversal on the usual process that Mr Scott said "suggests desperation" - and passed.

The media appearance came after a meeting between industry representatives and the Nationals party branch at Tamworth on Wednesday, which included Deputy PM Barnaby Joyce, Tamworth MP Kevin Anderson and MLC Trevor Khan.

Mr Humphries said he had put forward a three-year plan for the NSW government to consult and work with the industry instead of implementing an outright ban.

"Good governments do that, strong governments do that."

Mr Humphries said that, during AgQuip, he'd spoken to many leaders in animal-related industries, particularly breeding, who had asked, "What's next?"

"The reality is, we've opened up a Pandora's box on this issue. It needs to be put back in the box, legislation needs to be taken off the table and more consultation needs to take place."

Mr Humphries said there had been little thought give to the social and economic impacts of a ban, but he spoke up for his community on controversial issues "every day of my life", naming intensive livestock farming and broadscale farming as among those. 

"I'm hoping the legislation doesn't get put up on Tuesday... if it does get put up, I will be speaking against the bill".
