Hon CHRIS HIPKINS (Minister for COVID-19 Response): Not at this point, but what I would indicate is that we're working very closely with the airlines, with the World Health Organization, and so on around travel passports and the ability to share this information digitally much more readily, so that includes vaccine information and testing information. I think everyone would be of the view that the sooner globally we can get to the point where we can share this information more readily without people having to carry around pieces of paper—I think we would all like to get to that point. We're not at that point at this stage. One of the risks with text messages is that they are easily invented, and so it is more easy for people to present what appears to be a legitimate text message that isn't.
