Independent Andrew Wilkie will again write to the competition watchdog requesting an investigation into Tasmania's monopoly gambling deal with the Federal Group, after an overhaul of competition laws.

The Federal Government has announced it will adopt - in whole or in part - 44 of the 56 Harper Review recommendations handed down in March.

One of the recommendations accepted strengthens the powers of the Australian Competition and Consumer Commission (ACCC) to investigate deals struck by state and territory governments.

Mr Wilkie said he was hopeful it meant an exclusive gambling monopoly given to casino operator Federal Group by the former Tasmanian government could be scrutinised.

"Up until now, and obviously in regard to the deal with Federal Hotels, the ACCC has not had the power to intervene," he said.

Mr Wilkie said once the amendments had been made, he would be again referring the deal to the watchdog.

"Once the act is changed then I will very quickly write to the ACCC and say OK, you wanted the act to change, it has been changed, you now have the power to intervene when it comes to state governments involved in commerce," he said.

"Please now have a fresh look at the monopoly deal for Federal Hotels to operate poker machines.

The deal has previously been referred to the ACCC, but because of limitations of its power it could not investigate.

Mr Wilkie is confident the watchdog will find faults in the monopoly deal.

"I'm in no doubt that they will find serious fault in the arrangement we've had in this state since 2003 that one company, through a secret process, got a monopoly licence," he said.

Tasmania's Treasurer Peter Gutwein welcomed the change to the laws.

"The Tasmanian Government welcomes the opportunity to work with the states and territories, and the Australian Government, on the implementation of the recommendations," he said.

"Tasmania is already ahead of many of the other states in delivering outcomes.

"For example, we are getting on with planning reform, we are embracing the sharing economy such as Uber and we already deliver a variety of human services via competitive arrangements with the not-for-profit sector."

Federal Group declined to comment.
