NSW Deputy Premier Paul Toole says he has "made moves to rectify" his pecuniary interests declarations after questions were raised about rent paid on properties owned by him.
NSW Labor leader in the upper house Penny Sharpe accused Mr Toole of having "wilfully failed" to declare as much as $127,000 in rent collected on two properties he owns.
"In his entire parliamentary career he has never declared a cent," Ms Sharpe says.
Mr Toole listed himself as the sole owner of three properties and the joint tenant of another on his pecuniary interests disclosure in July this year.
Under "disclosure of other income" he wrote "N/A".
NSW Premier Dominic Perrottet told budget estimates on Thursday morning he would take action dependent "on the circumstances" if a minister had not disclosed all the information they were required to.
When asked about Mr Toole he took the question on notice but said if "that were to be true" he would raise it with the deputy premier and with the Department of Premier and Cabinet.
Ms Sharpe says Mr Perrottet's response was to "simply shrug his shoulders" when "faced with clear evidence of a wilful breach by his deputy premier" of the ministerial code Mr Perrottet oversees, and which his predecessor Gladys Berejiklian is currently being investigated by the state's anti-corruption watchdog for potentially breaching.
Mr Toole told AAP he sought clarification and has "already made moves to rectify" the issue.
"I have always sought to be transparent with my pecuniary interests and disclosed the ownership of all properties as required," Mr Toole said.
Ms Sharpe said Labor will "consider all options about taking further action on this matter".
