DAVID SEYMOUR (Leader—ACT): Thank you, Madam Chair. Rather seamlessly, I'd like to follow on from that and just ask the Minister in the chair, the Hon Chris Hipkins, about clause 4—Part 1, clause 4—which amends section 5 of the COVID-19 Public Health Response Act. It changes the interpretation. There's quite a number of new terms introduced into the legislation. There's a "vaccination authorisation", a "vaccination certificate", a "vaccination exemption". There's "exempt person means a person who has been granted a COVID-19 vaccination exemption", "specified COVID-19 vaccination exemption criteria", "vaccinated". These are all the new terms that are introduced.
