A man was discovered missing from his quarantine accommodation in Katherine late this week.
Police said the 57-year-old man was not at his hotel accommodation in Katherine at the time compliance teams came looking.
Police have since located the man and he was escorted back to his room.
It comes as the NT Government decides not to lift quarantine restrictions for people from coronavirus "hot spots" traveling to the NT from July 17.
The NT Government today announced while border controls will be lifted for everyone else from July 17, that will not include people from known community transmission areas.
At the moment, those "hot spots" are suburbs of Melbourne.
Any arrivals from a suburb or local government area which has been declared a coronavirus hot spot will be required to undertake mandatory self-quarantine for 14 days.
Hot spots will be identified by State or Territory Governments, or by the Australian Health Protection Principal Committee, and listed on coronavirus.nt.gov.au
In addition to the information currently provided on the border arrival form, arrivals will be required to declare if they have been in, or traveled through, a hot spot within the last 28 days.
Any person from interstate that lives in a hot spot area should be in lock down and therefore should not be traveling anyway.
Making a false statement in a statutory declaration is an offence that carries significant penalties.
People who have been in hot spots will be monitored to ensure they comply with their self-quarantine requirements.
The new restriction comes as Central and Northern Land Councils have called on the NT Government to keep the NT borders shut.
The land councils want the borders to remain closed "with all other jurisdictions closed until community transmission of COVID-19 has been eliminated in Australia".
The land councils also want mandatory hotel quarantine for 14 days reinstated.
The land councils said the NT Government must implement the 'Contain and Test Strategy' in all remote communities, irrespective of what is in the local community's pandemic plan.
It calls on the government to "implement a community engagement strategy so every person in a community knows what will happen if there's an outbreak".
It also asks the NT Chief Health Officer to immediately re-issue an order requiring everyone except for close family members to comply with physical distancing rules in public.
The Northern Land Council supports the Central Land Council resolution.
"I'm not at all for the borders to open on July 17," NLC chair Samuel Bush-Blanasi said.
"Chief Minister Michael Gunner should really be talking to the land councils about reopening the border at a later date because of the hotspots in Melbourne and elsewhere," he said.
Northern Territory Police have issued four infringement notices for failing to abide by the Chief Health Officer Directions issued under section 56 of the Public and Environmental Health Act 2011.
Compliance teams continue to conduct checks on people who entered the Territory after the easing of quarantine restrictions, allowing people to nominate a place of quarantine rather than hotel accommodation.
Two people, aged 19 and 24, were both absent from their homes in Darwin at the time of checks. They were contacted by Police and were unable to provide a lawful justification as to why they were not quarantining.
A 27-year-old man, who traveled from Sydney to Darwin, breached quarantining when he was located inside a casino. Police located the man and he was escorted back in his hotel in Marrara.
Commander Matt Hollamby said, "Police have issued 12 infringements so far this week.
"Each person that has been issued an infringement has no justifiable reason to be breaching their quarantine and each represents a potential risk to the wider community. They are blatantly ignoring directions they are given when entering the Territory."
The infringement penalty for an individual is $1,099 and $5,495 for a business.
NT Police and Environmental Health Officers continue to undertake compliance activities.
18,605 compliance checks have now been completed and 83 fines issued.
