Rt Hon JACINDA ARDERN: I'd point the member to the fact that most of those countries who have those digital tools have also been using them as certificates for entry to different sites and so on. Of course, we are not in that position currently. We do have an ability for people to access a demonstration, a certificate of sorts, that they have been vaccinated. People have been doing that through the Ministry of Health and, as I've said in this House before, we are currently working on a digital model that will allow people to be able to carry that information certification with them, and we expect that to be completed shortly.
