The Gillard government reforms included a requirement that machines be equipped with pre-commitment technology,which could in the future be used to require players to set the amount of money they are prepared to lose before playing.
Other measures set to go include requiring electronic warnings to be displayed on machines,the creation of a national gambling regulator and a $250-a-day cap on automatic teller machine withdrawals in gaming venues.
Labor's reforms,which passed Parliament in November 2012,were criticised as a watered-down version of the changes it promised independent MP Andrew Wilkie in return for his support in the hung parliament.
But anti-gambling campaigners have urged Labor to defend their reforms,warning that no future federal government will have the courage to tackle problem gambling.
Independent Senator Nick Xenophon condemned both major parties.
''Can I just say,shame on the ALP,and shame on the coalition for repealing even minimalist reform on the poker machine industry,''he told reporters on Tuesday.
