Hon CHRIS HIPKINS: Well, if the member's setting a very low threshold for what a vaccine certificate is—such as the little blue card that people get after they have been vaccinated being the equivalent of a vaccine certificate—then he's welcome to make that claim. But that is about as sophisticated as many of those systems get. We're developing a system that will be a lot more robust, that will stop people ripping off the system and claiming they've been vaccinated, when they are not. One of the things that we've been working through, as I just told the member, is being very clear on where vaccine certificates will be used and where they won't be, and on this side of the House we have clear answers to those questions.
