Tamworth MP Kevin Anderson is "relieved" to have tested negative to COVID-19 after being forced into isolation after attending a Nationals state budget dinner in Sydney, on Tuesday.
However, Mr Anderson will remain in isolation until at least July 6 and will continue to undergo tests for the virus.
The news comes after Northern Tablelands MP Adam Marshall tested positive to COVID-19 on Thursday, after being exposed to the virus when dining at a Sydney pizza restaurant on Monday night.
Mr Anderson was deemed a close contact of Mr Marshall's.
Mr Anderson had travelled back to Tamworth before he was ordered to get tested and isolate for 14 days, regardless of the result.
"It just goes to show it can happen anywhere, any time," he said.
"You can get caught up in a situation where you don't even know that there is a problem.
"I've gone to parliament, gone to my work - a lot of people travel away for work - and I've travelled home like I've done hundreds of other times as well.
"And it wasn't until I was at home that I was notified there was a possible positive case in parliament."
Mr Anderson was notified of his negative result at about midnight Thursday. He now needs to test negative two more times before he can come out of isolation.
But the local MP said it's business as usual and it will be straight back to focusing on the electorate, just not face-to-face.
"I'm set up to work from home while keeping our community safe, it will be business as usual for me," he said.
"As far as I'm concerned you've got to take these things seriously, and a lot of people are still working from home so I'll do the same."
One of Mr Anderson's staff members is also in isolation, but his Tamworth staff will continue to operate.
Meanwhile, Deputy Premier John Barilaro has confirmed he has tested negative to COVID-19, but will remain in isolation for 14 days after also being identified as a close contact of Minister for Agriculture Adam Marshall.
