ALL poker machine venues in Australia, regardless of size, will pay a new government tax to help fund national pokies reforms, although the price is yet to be set.

The government's watered down pokies reform, finally agreed to by the Greens last week, will require all poker machines to eventually have pre-commitment technology that will allow punters to preset how much they are willing to lose.

Legislation associated with the reforms imposes a ''supervisory levy'' on venues that will be used to fund the scheme - the price of the levy has not been set yet but the government says it will not raise a dollar more than is needed to fund the scheme.

The levy's rate will not be set until after legislation is passed.
