A bill barring NSW ministers or parliamentary secretaries from seeking or accepting commissions from property developers has passed parliament.
The NSW upper house on Thursday passed the change to the ministerial code of conduct and the lower house on Tuesday accepted the proposed amendments to the Statute Law Bill 2020.
It comes after ex-MP Daryl Maguire last week in ICAC confessed to secretly directing G8way International, a firm that earned commissions for linking Chinese buyers with Australian businesses, while in parliament.
ICAC also revealed that Premier Gladys Berejiklian was in a clandestine five-year "close personal relationship" with Mr Maguire.
"It is the right thing to do - most people would have been outraged when they saw the premier's response to Daryl Maguire receiving a commission from a property developer and that response was 'woohoo, well done, congratulations'," Opposition Leader Jodi McKay told reporters on Tuesday.
"Their job is to represent their community - they should not be moonlighting with property developers and earning extra income."
Ms McKay argues Ms Berejiklian's failure to declare her relationship with Mr Maguire constituted a breach of the ministerial code of conduct.
Ms Berejiklian remained the focus of opposition attacks in question time on Tuesday. She was asked why she failed to report Mr Maguire's business activities to ICAC despite discussing them in recorded phone conversations.
"We should allow the integrity body to do the work it has to do while I do the work NSW people expect me to do," Ms Berejiklian responded.
