Almost two thirds of people in New South Wales and the ACT support the decision to end greyhound racing, despite the issue becoming a political hot potato for NSW Premier Mike Baird, a survey by the RSPCA has found.

The independent survey of more than 800 people, commissioned by the RSPCA, found that 64 per cent of NSW and ACT residents were in favour of banning the sport, leaving 36 per cent opposed.

The decision to ban greyhound racing in NSW, which the ACT Government subsequently followed, sparked a backlash against Mr Baird from within his own party and from coalition partners the Nationals.

But according to the survey, support for the ban was not affected heavily by party affiliation.

"It showed that support runs across geographical and party political lines as well," RSPCA spokesman Jed Goodfellow said.

"The decision is not about politics but about animal welfare."

Mr Goodfellow rejected the framing of the decision as an attack on working class and rural voters.

"It's certainly below the 77 per cent response rate in support of the ban in metropolitan areas, but 59 per cent of rural areas still support the ban as well," he said.

"Despite the political rhetoric that has surrounded this decision, we still see that the majority of people in the so-called working class are supportive of the Government's decision."

The study also found that 80 per cent of people who supported an end to greyhound racing did so because of concerns about animal welfare.

Figures show support for ban falling: Greyhound industry

However Kel Watt, a spokesman for the Canberra Greyhound Racing Club, said support for the ban used to be stronger — a sign greyhound trainers were winning the debate.

"It was just two months ago, after the release of the NSW Special Commission of Inquiry, that a survey showed over 80 per cent of people were supportive of a ban," he said.

"It shows that support for a ban is being eroded away very, very quickly as people become further aware of the lies being promoted by the RSPCA.

"The RSPCA is no longer concerned about animal welfare, they've become an animal liberation group and for the most part, are now being run by a bunch of zealots."

Mr Watt also cast doubts over the accuracy of the RSPCA's findings.

"Given the fact that the campaign for two years being run by the RSPCA ACT has been based on lies and deceit, I've even got question marks around the accuracy of this," he said.
