Hon CHRIS HIPKINS: People can access their vaccination records now. They can go and download them off the internet right now if they wish to do that, and if they wish to print them out to show other people that they have been vaccinated, they can access that now. But one of the issues is that people want to know that they have been validated, and so making sure there's a technological solution available that respects people's privacy and that allows for digital vaccination certificates to be validated is one of the pieces of work that is now in its final stages. Of course, though, one of the things that has to be resolved, and that did need to be resolved before this system could go live and be finalised, is exactly how they would be used. I can say, on this side of the House, we're very clear on how vaccine certificates will be used.
