The Department of Health in Northern Ireland has reported a further 20 coronavirus-related deaths in the past 48 hours.
In the same period, 1,634 people have tested positive for Covid-19.
It comes as Northern Ireland's health minister urged the public to strictly adhere to the new lockdown measures.
Robin Swann called on everyone to "play their part" during the next six weeks, which he described as a "crucial period" in the pandemic.
Businesses across Northern Ireland closed once more as the new measures came into effect from 26 December.
Additional restrictions are in place until 2 January, including a form of curfew in operation from 8pm, with shops closed from that time and all indoor and outdoor gatherings prohibited until 6am.
The sweeping measures also involve the closure of non-essential retail and close contact services such as hairdressers for the next six weeks.
Hospitality outlets are limited to takeaway services.
Mr Swann said: "We need another huge collective effort across society to push down Covid infection rates.
"We do that by reducing our contacts with others, by staying at home, by keeping our distance from others if we need to be outdoors for good reason, and by wearing a face covering and washing our hands.
"This will save lives and ease the pressures on our health service at this most challenging time.
"I know how tough 2020 has been and how fed up we all are with this virus. But I am confident we can all pull together once again at this critical time."
He said the new year has "renewed hope with the vaccine rollout", but added: "We need a concerted and united push in the next few months to get us to a better place.
"Please stay at home as much as possible. Please don't be tempted to visit friends this week. It's not just about complying with the regulations, it's about keeping yourself and others safe.
"A New Year's Eve house party would not just be against the law. It could be a super-spreader event, could leave people very seriously ill and could even cost lives."
The Northern Ireland Executive is underlining the "stay at home" message this week with adverts on TV and radio.
Meanwhile the Northern Ireland Assembly is set to be recalled to discuss the Brexit trade deal. The Stormont Executive agreed the move in a special meeting which was held virtually this afternoon.
The DUP confirmed its MPs will vote against the Brexit trade deal.
Party leader Arlene Foster said: "Whilst recognising this agreement brings about tariff and quota-free trade between the UK and the EU and thus reducing the impact on the GB to NI trade flows, we still have many negative issues arising from the Protocol.
"On that basis we will vote against this agreement. We will continue to work to mitigate the worst excesses of the separate Northern Ireland arrangements whilst exploring new opportunities for Northern Ireland.
"Our challenge going forward will be to press the government to get a better outcome in those areas where more work is needed.
"These arrangements flowing from the protocol are of course temporary, in that the Northern Ireland Assembly will have the opportunity to revisit the protocol and vote upon it in four years' time."
