And he has labelled the broken promise a trashing of democracy.

Mr Wilkie tore up his agreement of support for Labor after it announced on the weekend it was backing down from introducing a mandatory pre-commitment scheme by the end of 2014, in favour of a year-long trial in the ACT.

The Tasmanian MP said he doubted the government's intentions.

Last week he met with WA National Tony Crook, who told him the Government had only approached him once about supporting the legislation.

"He had barely been lobbied," Mr Wilkie told ABC Radio.

"So there is a prima facie case that the government was never going to honour it."

Prime Minister Julia Gillard says the plans have only been watered down because of a lack of numbers in the parliament - but Mr Wilkie begged to differ.

"If it had been put to the test, the numbers would have been there," he said.

"We shouldn't be trashing our democracy by doing compromise deals and backroom deals outside of the chamber."

Labor's new approach to pokies reform includes making all new poker machines manufactured from 2013 pre-commitment ready, a $250 daily limit on ATM withdrawals at clubs and electronic warnings on machines by 2016.

Mr Wilkie conceded the reforms were still remarkable and would make a difference to problem gambling.

However, he will cease his weekly catch-ups with Ms Gillard and warned the Government to tread carefully in its future interactions with him.

"It's a much more fragile one-seat majority than it had previously, there's been much said about (Speaker) Peter Slipper, (Labor backbencher) Craig Thomson - something else could happen," he said.

"The Government would be quite foolish to burn me."
