Rt Hon JACINDA ARDERN: Again, just a bit of context: of course, there has been a period where the world had no vaccines in which we were still operating our ports. So we have had orders in place that mean that, for this entire time, we have treated every ship as if those who are on it have COVID. Keep in mind there is no requirement to test every single cargo ship that comes into New Zealand, because we have 2,000 a year, and some ships, (a) don't stay long enough, (b) would risk those individuals coming off ship when they are currently banned from doing so, and there is also the risk that they would not come. So we behave as if every cargo crew has COVID. There are requirements around social distancing; personal protective equipment use if you may come into contact; and now, on top of that, we have mandated vaccinations.
