Hon CHRIS HIPKINS: The details for the plans for the broader roll-out are being released progressively as we reach each stage in the roll-out. So the first stage of the roll-out is our border workers. We've got a detailed plan there which we have shared, and people are aware of what's happening there. As we move forward, as we receive additional deliveries of vaccines, one of the things that we do need to be able to do is tweak the vaccine roll-out plan, if you like, depending on what we know about the vaccines that are arriving. We've got four different vaccines that we've bought for New Zealand. We understand more as each day goes along about who those vaccines are the most effective for, and so we need to be able to tweak our detailed implementation plans as that information comes to light, as our Medsafe approvals process shares more information about those vaccines with us and as the delivery schedules for the different vaccines get locked in.
