So things like vaccine passports—no, it's not feasible for New Zealand to develop its own vaccine passport system; it would be futile to do so if no other country could read it and interact with it. We want to be part of a system that's global; that means that people can share that information seamless and instantly; and that New Zealanders can share their vaccine information, their testing information, and so on, as part of the prerequisite requirements to travel internationally. So we've got to be right in there with those conversations. So there isn't certainty here.
