As Dr Dean Knight from Victoria University of Wellington Law Faculty has said, this bill is a constitutional disgrace. It should have been worked on for quite some time. And the reason for that is actually the reason highlighted by the Minister in his contribution around choice. He made the correct point, which is that the decisions that some people make to be unvaccinated have externalities. He didn't quite phrase it like that, but in economics terms, that's what they are. They have externalities. My decision not to be vaccinated has a consequence, not just for me—that's true, in a personal sense—but it also has a consequence for the health system and for others, because kids can't be vaccinated and there are other people who can't be vaccinated. And it's worthwhile having a debate about that.
