There are, in addition, announcements at the airport, via the public address system, emphasising just that New Zealand has a zero-tolerance approach at the moment. Every single passenger, as you know, because we've closed our e-gates, has to go through Customs and they're manually processed in that way and they are asked again about self-isolation, they're given a card to call the Healthline, and after that they then go to the Ministry for Primary Industries (MPI), and MPI also asks our passengers that come through our international airports, and makes them know about self-isolation.
