Rt Hon JACINDA ARDERN: I see that those port workers are part of our next sweep. And, again, we're asking Health to work up the matrix of the frequency of testing across ports, across airports, across all sectors. What I would add, because it is slightly misleading: again, as we have always said, testing is not sufficient on its own. We have a maritime order in place, for instance, that dictates how those international freight crew must behave when they are at our ports—that includes not being able to move beyond the port side if they have not returned a negative test. They also have to have been at sea for a period of 14 days; we did have a longer period, but we added testing into that regime. They also must practise social distancing to make sure that we maintain safety for port workers, and, of course, we have a regime around surveillance testing.
