Face coverings look set to be made mandatory on public transport as capacity increases to 50%.
The cabinet is expected to sign off on the plans at a meeting this evening.
It's also expected to approve moving to phase three of easing restrictions from Monday - after the National Public Health Emergency Team meets this morning.
Jack Lambert, a professor of infectious diseases in the Mater Hospital, says masks should be compulsory in many different settings.
"When you're on a bus everyone should wear a facemark.
"If they're opening up the pubs and they're opening up the restaurants, all of the servers who are not going to be socially distancing 100% of people involved in these industries, they should be wearing face masks because they're there all day.
"So yes, face masks should be mandatory in certain situations."
