Officials from the National Public Health Emergency Team (NPHET) also reported no further deaths from the disease.
Of the new cases, 65 per cent are aged under 45, and 52 per cent are associated with outbreaks or are close contacts of a confirmed case.
166 of the cases are located in Dublin, 21 in Cork, 19 in Donegal, 7 in Kildare, 7 in Offaly, 6 in Waterford, 6 in Wicklow, 5 in Louth, 5 in Limerick and 5 in Meath and the remaining 27 cases are located across 12 other counties.
There have now been 32,538 confirmed cases of the disease in the Republic, and 1,792 Covid-related deaths.
Meanwhile, more than 200 new cases of Covid-19 have been confirmed in the last 24 hours in the North.
It is one of the biggest daily increases in the region since the start of the pandemic.
According to the Northern Ireland Department of Health’s daily figures on Saturday, there were a further 222 new confirmed cases of the virus.
This brings the total number of cases in the region to 9,165, including 913 in the last seven days.
There have been 575 deaths with Covid-19 in Northern Ireland, according to the department’s figures.
The news comes as new Covid-19 restrictions came into force in Dublin overnight.
People are not allowed to enter or leave the city and county unless it is for work, education or other essential reasons.
The region is on Level Three restrictions which mean bars and restaurants cannot serve food indoors – many had to close last night.
No more than six people from one household can visit another home, all indoor gatherings are banned and organised outdoor gatherings are limited to 15 people.
Many communions and confirmations set for this weekend have been called off – however, weddings and funerals can continue under Level Two rules until Monday.
Taoiseach Micheál Martin said there will be more gardaí on patrol in Dublin this weekend.
"I think there will be an increased presence, so we can reduce large gathering and gardaí, in their operational duties, make judgement calls on that every day and every week and they will continue to do so.
"Fundamentally, we must get across the message that the numbers are rising. We've got to arrest the growth in cases," said Mr Martin.
