The Big Rivers region has the lowest COVID-19 vaccination rate in the NT, according to the latest figures.
According to NT Health, a total of 36 per cent of people had received their first jab in the region, and 24 per cent of people are fully vaccinated.
Big Rivers, which includes Katherine and its 18 surrounding towns and communities, has the lowest vaccination rate out of the NT's five regions.
The vaccination rate, however, is high for a number of individual communities.
In Numbulwar, 72 per cent of people have received their first jab and 65 per cent have received their second.
However, it remains unclear how the vaccination rollout is going in the other remote communities of the region due to an agreement by the Aboriginal Medical Services Alliance NT (AMSANT) to keep the data of communities serviced by Aboriginal Community Controlled Health Organisations private.
Chief Minister Michael Gunner said today that the vaccination rates from those remote communities are being discussed with the NT Government, but are not to be publicly disclosed.
"I have seen a breakdown. I do know for example Congress, they were freely discussing the rates with me when I was in Alice Springs yesterday, but I don't get permission to talk to what their rates are."
Mr Gunner acknowledged that misinformation on Facebook is contributing to vaccine hesitancy in some communities in the region.
AMSANT CEO John Paterson told the ABC the reason for the privacy agreement was to prevent shaming of individual communities, many of which have very small populations.
"We should not be ... publicly identifying individual communities and making it a 'they're'-doing-better-than-us' [situation]," he said.
"I think we do it sensitively, we do it culturally appropriately and we do it in partnership."
