Health Minister Robin Swann is expected to recommend a tightening of the Covid-19 restrictions at a meeting of the NI Executive, currently under way.
It is thought he will recommend lowering the number of people allowed to meet indoors from 10 to six.
The move is in response to a marked increase in the number of coronavirus cases in recent weeks.
The Department of Health has confirmed 51 new positive cases of the virus in NI, bringing that total to 6,556.
No further deaths have been recorded by the department, meaning its death toll remains at 559.
On Thursday, the head of the Public Health Agency said localised lockdowns were “practically inevitable”.
It is one measure thought to be under consideration by Stormont’s health officials to curb the spread of the virus.
Dr Gerry Waldron said Covid-19 had been spreading much quicker than the PHA expected after restrictions were eased earlier in the summer.
He said: “If things continue as they are going, I think it’s [local lockdown] practically inevitable, but hopefully people will take heed of the issue.”

He added that some people who had tested positive for coronavirus, or had been in contact with someone else who had, were ignoring the advice to stay at home and self-isolate.
He said: “By doing that, they are putting individuals they come into contact with at risk.”
The number of new daily cases is up significantly from the end of June.
‘We have to step in now’
It is understood ministers may also raise questions about plans for pupils to return to schools and the effect the upgrading of exams for school leavers will have on local colleges and universities.
Speaking on Wednesday, Mr Swann said “we have to step in now” to deal with the rise in new cases.
The health minister said there was no one trend to explain the recent rise in case numbers – otherwise it would be easier to act.
“We cannot put our finger on any specific, either location, or activity or industry, as to a cause of the number of increases and positive tests we have seen.”
He also refused to rule out a return to full lockdown in the coming months.
Decisions on restrictions will be made after ministers have taken advice from the Northern Ireland Chief Medical Officer Dr Michael McBride and Chief Scientific Adviser Prof Ian Young.
Prof Young said on Wednesday that Northern Ireland has a higher rate of Covid-19 per 100,000 of the population than the rest of the UK at present.
He said there had been a tenfold increase in new infections since the beginning of July, with almost 300 new cases being confirmed in Northern Ireland in the past week.
Northern Ireland’s rate currently showed 24 cases per 100,000 over the past 14 days, evidence that pointed to the virus spreading again, he added.
In the Republic of Ireland, lockdown measures which had previously been lifted have been reversed – with restrictions placed on the numbers allowed to gather in indoor and outdoor spaces.
Indoor gatherings – excluding shops, restaurants and other businesses – are to be restricted to six people.
Those aged over 70 are again being asked to stay at home as much as possible, and it is recommended that people work from home and avoid public transport.
On Wednesday, the Republic of Ireland’s Department of Health recorded two deaths from the virus and an additional 54 cases.
There have now been 1,775 Covid-19 related deaths in the country and 27,547 cases.
