I want to talk about what's happening at Auckland international airport, because that is the largest port. So since the announcement that our Prime Minister made, these are some of the things that are happening at Auckland international airport. On the plane, for all international planes, there is an announcement there that actually tells people about the strict regulations and rules that we have around COVID-19. Second, passengers are given a health card and in addition to that, of course, the Customs form that they have to fill out: the arrival card. Third, there are extensive signs right across the airports, right across all of our international airports that you cannot miss, about the fact that we are really strict at our border. Fourth, passengers are now spoken to by a health official and have explained to them the self-isolation that they must actually do. And passengers are also questioned by these health officials.
