The rules for entry into the red zone are changing on Tuesday, and Civil Defence is warning people not to get caught out.
A paper-based system for those requiring limited access to the red zone expired on Monday and has been replaced by a new photographic pass.
Civil Defence says anyone found in the red zone without the new pass will be detained by the police.
Residents living in the cordoned areas and the red zone can continue to use photographic ID and proof of address at the checkpoints closest to their home.
