In terms of vaccine data collection at the border, that is being operationalised at the moment. MIQ are asking people about their vaccine status as part of the on-boarding, if you like, the bringing into the country process, as people come into MIQ. I haven't seen yet that compiled in a way that can be reported, but that process is under way. Ultimately, I think in the immediate term, it's likely to be built into the—I can never remember the acronym we use in New Zealand for it, but the electronic travel authority process that we've got at the moment, I think we'll have a vaccine question built into that fairly soon. Again, the process is under way to operationalise that. The ultimate goal, of course, is that it gets built into the information that's stored on the chip of somebody's passport so that when you're swiping through SmartGate or through any border anywhere around the world, it's just all done automatically; that's the ultimate goal. I can't give a specific time frame on that because that's largely an international discussion that will have to happen.
