NSW Customer Services Minister Victor Dominello has gone back into isolation as a close contact of a COVID-19 case after being wrongly advised he was a casual contact and could leave self-quarantine.
NSW Health in a statement on Wednesday night said it had apologised to Mr Dominello for providing incorrect advice to him.
That advice related to his exposure in NSW Parliament to a COVID-19 case diagnosed on Thursday, June 24.
Mr Dominello left isolation on Saturday after receiving a negative test result and advice from NSW Health he had been classified as a casual contact.
He immediately re-entered isolation when contacted by NSW Health on Wednesday afternoon to advise he remained a close contact.
"An urgent COVID-19 test was performed and this test returned a negative result," NSW Health said.
The minister is to remain in isolation until July 6.
"His two negative test results mean he has not posed a risk while in the community or to those he has interacted with in recent days," the department said.
It said a risk assessment determined his proximity in the chamber during Question Time on Tuesday, June 22, for an extended period of time made him a close contact.
The risk assessment of a further exposure event in his office that day determined he was a casual contact and on Saturday he was informed he could leave isolation after receiving a negative test result.
"NSW Health apologises for this error."
