Rt Hon JACINDA ARDERN: I'm not sure that it would necessarily be wise, based on what we see with other countries, to put an end date on the use of public health measures. I notice that even, for instance, the UK, who have tended to be one of the more liberal managers of COVID-19, have still maintained the position that, given winter, they may yet move to what they've called their "Plan B", which does bring some public health measures, including the possible use of vaccine certificates, back. So I do think that we would be wise to continue to wait and see what happens over the ongoing trajectory of the pandemic, particularly once countries who are vaccinated, with high rates, move into a winter period.
