Rockhole will transition from a hard lockdown to a regular lockdown from midday today after another day of negative wastewater testing in the community.
It comes as Chief Minister Michael Gunner told media on Thursday morning that one new case had been recorded in the NT - a teenager from Binjari who was already in the Howard Springs quarantine facility.
No one has tested positive to Rockhole so far during the outbreak, with wastewater testing from the community returning consistent negative results.
"Rockhole will transition from hard to ordinary lockdown today at noon," Mr Gunner said.
"Under no circumstances are residents of Rockhole permitted to enter the Binjari community."
Residents of Rockhole will now be able to leave home for the five reasons; for medical treatment, for essential goods and services, for essential work, for one hour of exercise and to provide care for someone who cannot support themselves.
Following the news that a woman who tested positive to COVID-19 left Binjari and went to Katherine on Tuesday night, the Shell Coles Express on the Stuart Highway has been listed as a close contact site on November 23 4.50 - 5.05pm.
Mr Gunner said although there were only two check-ins, CCTV shows there were more people there at that time.
"If you went to the servo Monday arvo and did not check in, you are a close contact you're required to contact us, get tested and isolate for 14 days," he said.
Meanwhile, the casual contact site of the Salvos shop on November 13 has been upgraded from a casual to a close contact site.
"There are only two days left in the replication cycle for this site, but we now have evidence that more than one positive case was there at the same time," Mr Gunner said.
"We need anyone at the shop during that time period to get tested and stay isolated until a negative test returns."
Acting Chief Health Officer Dr Charles Pain said authorities were "actively considering' when to transition Katherine from lockdown to lockout.
"We're obviously looking at the wastewater, we're looking at cases. To see if there any new cases because you have this exposure site," he said.
"A lockdown to lockout transition decision is imminent, but I wouldn't like to raise their hopes [people in Katherine]."
