Rt Hon JACINDA ARDERN: There are a range of circumstances for each of those countries where that may be the case. So, for instance, if we take until recently the Cook Islands, there is an example of where we had a reasonable level of confidence, of course, that there weren't incursions of COVID, but they, at the same time, did not have PCR testing in place, and that will be a similar case in other parts of the Pacific. Of course, we've had health officials in, we've been working alongside the Cooks, and we've now removed that quarantine requirement. So, in each case, there will be different circumstances that may lead to the requirements that we have in place.
