People in Wales will need to show a pass proving they have been fully vaccinated or had a negative Covid test to attend clubs and large-scale events.
The new rules begin on 11 October.
Customers will be able to use an NHS Covid Pass to show they have been vaccinated, or had a negative lateral flow test in the past 48 hours.
The pass will be needed for clubs, indoor no-seating events with more than 500 people and outdoor no-seating events with more than 4,000 people.
It will also be required for any event with more than 10,000 people.
