Northern Ireland’s finance minister, Conor Murphy, said on Sunday that further steps will be considered by Stormont if the current Covid-19 measures are not effective.
Mr Murphy told the BBC’s Sunday Politics all options would be discussed when the Executive meets on Monday.
He also said he was working to quickly put in place a package to support businesses forced to close their doors as a result of Covid-19.
“We recognise that if businesses are forced to close down in hospitality that there will be going costs that they will need assistance with,” he said.
“What we want to do is put a scheme in which gets support onto the ground very quickly, which isn’t overly bureaucratic, which recognises that this may be in place for a couple of weeks and that people need support with ongoing costs.”
He said that the furlough scheme was still available until the ned of the month but they still wanted to get a new support package on to the ground. that went “directly to those who need it”.
The Stormont Executive announced new restrictions for the Derry City and Strabane Council area on Thursday in an effort to stem spiralling infection numbers.
They include hospitality businesses being limited to takeaway, delivery and outdoor dining, and a call to avoid unnecessary travel.
A total of 65 patients with Covid-19 were being cared for in 20 hospitals in the region on Sunday, with nine in intensive care.
