Here's the other thing that people that work in hospitals tell me. Our isolation rules are unworkable. The Prime Minister found this herself. Her partner got COVID—a week in isolation. Then she got it and had another week. That is happening in families across New Zealand. Every principal of every school is suffering at losing a teacher for two weeks because of a few days of infectiousness. That's what's happening in the hospitals. They're losing their nurses. We should do what Singapore does and say you've got 72 hours stand-down; out with a negative test. We should dump the household requirement, just as Australia, for example, has so that people can get back to work. That's just one of the 99-plus problems that we could solve if we took a practical approach to the shortage of nurses.
