Rt Hon JACINDA ARDERN: Keep in mind, some of those countries have used them to access venues and the like, and, of course, what we're trying to do is ensure that we have something that is able to be used when moving through borders, as well, so multiple purposes. My recollection from the time line of health officials is that they're working on it currently. They're looking to have, I believe, something that will be available, I think, in the latter part of this year, so near the end of the year. They'll want to, of course, make sure that they're trialling and piloting it. I have to say, some of the digital solutions that our health team have worked on—be it the booking system, which, prior to now, didn't exist; improvements to the immunisation register, which, previously, I have to say, we inherited a bit of a dog's breakfast on the immunisation register; and then, also, the work they've done to develop the NZ COVID Tracer app—just demonstrate the incredible work that that digital team has done.
