Dr LIZ CRAIG (Labour): Thank you, Mr Speaker. So just looking back to when all of us rapidly entered alert level 4 early last year, I think none of us knew what to expect, and yet when you actually look at what happened in the months that have followed, we've been incredibly successful at preventing the spread of COVID-19. I think a lot of that is due to the fact that we had a really good, consistent framework—a framework that included our very clear four-level alert level system, which we've all become incredibly familiar with—and also just very clear requirements about entering managed isolation and quarantine (MIQ) for anybody coming into New Zealand. Underpinning all of that has been the COVID-19 Public Health Response Act. That Act has worked by allowing for the creation of orders which then result in the development of many of our public health responses that have influenced so much of our day-to-day life over the past few months.
