Corrupt former ministers Eddie Obeid and Ian Macdonald will be allowed to keep potentially millions of dollars in taxpayer-funded superannuation, even if they are convicted and jailed.

Premier Barry O'Farrell is refusing to commit to proposed changes that would allow Parliament to strip the pair of their entitlements, worth more than $100,000 a year for life, following the damning findings against them.

Opposition Leader John Robertson wants to amend laws governing the state politicians' super scheme after it emerged former state MPs are entitled to keep their pension even if convicted of a serious criminal offence.

The Independent Commission Against Corruption found Mr Obeid and Mr Macdonald acted corruptly by conspiring to rig a tender for a mining exploration licence on land owned by the Obeid family at Mount Penny in the state's west.
