The latest allegations aired at the Independent Commission Against Corruption (ICAC) have prompted calls for the Premier to move to freeze the assets of former Labor power broker Eddie Obeid's family.
He says the law allows for assets to be frozen where there is a reasonable suspicion they were acquired as the result of criminal activity.
"These are laws that are used regularly against drug dealers, before they're charged before they're found guilty," he said.
A spokesman for the Premier confirmed the Crime Commission already has the power to seek to freeze assets.
He says that power extends to matters that may be before the ICAC.
Meanwhile a new alliance of community groups has joined calls for the Premier suspend the mining licenses at the centre of the corruption watchdog's investigation.
Hunter and Central Rivers Alliance spokesman Graeme Healy says the State Government made election promises to review the way exploration licences are issued.
"Since they've come to government, these promises have been found to be of no value at all," he said.
Back on the stand
In the witness box, Mr Obeid was chastised for failing to answer questions asked by Counsel-Assisting Geoffrey Watson SC.
He was reprimanded for interrupting, and told he could have his barrister Stuart Littlemore QC removed from the room if he wanted to run his case himself.
The 70-year-old was also reminded he was not in parliament.
But Mr Obeid denied he was involved in any sort of criminal conspiracy against the people of New South Wales.
He denied knowing how confidential mining maps got into the family's Sydney headquarters and denied knowing his sons were buying two properties because they were covered by a new mining tenement.
He also denied being the beneficiary of a family trust.
When asked what he told the ALP about the Obeid family making huge profits from a decision made by Mr Macdonald, Eddie Obeid replied, "nothing."
Ian Macdonald is due to give evidence on Thursday.
