Poultry gatherings will be banned from noon on Monday to try and stop the spread of bird flu.
The Animal & Plant Health Agency said it was in response to the rise of cases in kept and wild birds.
It said poultry gatherings – including ducks, geese, swans, pheasants, partridge, quail, chickens, turkeys and guinea fowl – would not be allowed.
Gatherings include – but are not limited to – bird fairs, markets, shows, sales, exhibitions and some premises used for dealing or internet sales.
Vehicles used to transport live birds where the birds are brought together from multiple premises are also considered as gatherings.
Gatherings of other captive birds will continue to be permitted, providing organisers follow and meet all the requirements of the captive bird gathering general licence.
