NSW Premier Gladys Berejiklian has confirmed no new cases have been confirmed for Armidale.
Tamworth also recorded no new cases, but testing numbers remain low.
Ms Berejiklian said the lack of cases in both areas is a positive sign.
"In terms of regional New South Wales, pleasingly Armidale, Tamworth and Northern Rivers continue to have zero cases which is a positive sign, those three local government areas or communities who are currently in lockdown continue to have zero cases," she said.
"Unfortunately the same isn't the case for Hunter and New England where there has been a number of cases overnight and as a response to that, NSW Health has recommended that those local government areas which are currently in lockdown including the Hunter and the upper hunter areas will be extended by another week, so rather than coming out of lockdown tomorrow, that will be extended another week given the additional number of cases and I think given what the area is experiencing the community would understand why that is the case."
In Dubbo there were five additional cases overnight and one in western NSW which have put communities in lockdown.
NSW broke a vaccination record yesterday with 150,000 people fronting up.
There were 345 cases in the 24 hours to 8pm and 60 of those were infectious in the community during that time.
Unfortunately, two people died overnight, both were men in their 90s; one was fully vaccinated and the other had the first dose of AstraZeneca.
Armidale's vaccination hub will open for five hours on Saturday, residents will be able to arrive without a booking to get the COVID-19 jab.
It's the only walk-in vaccination centre in the region, and was organised in just a matter of days this week after UNE offered the use of its medical centre during a meeting of Armidale's emergency services.
Armidale's COVID-19 outbreak started when two positive cases were reported last Saturday, and stay at home orders came into force at 5pm that day.
Tamworth MP Kevin Anderson has said he is still waiting for the results of sewage testing in the Tamworth region.
Mr Anderson confirmed on Wednesday that testing has been bumped up to twice weekly due to the precautionary lockdown.
It comes as local leaders have made a renewed call out to the community to get tested.
A lack of tests is a major concern as a 72-hour return time means there's a very real possibility that positive COVID-19 cases could be yet undetected in the region.
Members of the community who were tested for the virus on Monday have said they are still waiting for test results.
