Rt Hon JACINDA ARDERN: We traversed this in great detail yesterday. Of course, they have been able to access a vaccine since the very beginning of our roll-out. We prioritised port workers, so that was right at the start. We wanted them to be in that queue. One of the issues that was raised with us by port companies was that if we had critical port workers who did refuse or did not take up that initial offer, if we were to mandate it and have job loss, we may see a complete stop in some of our supply chain, which was already under a lot of pressure. We took the decision to mandate, but on a time line that, working alongside ports, they believed that they could work around if they did have critical workers drop out. I would highlight, in fairness to the ports, that, actually, of those directly employed by the ports, we've had reasonable uptake. It is often those who are contracted by the ports to come in where we have had lower uptake.
