So the day three test would seem to be absolutely critical, and yet the argument that I'm hearing is "Oh, don't worry; they're having a day 12 test." If you have a day three test and you're positive—like the people in Hamilton not last weekend but the weekend before—what happens is that you escalate, if you're in managed isolation, to a higher level of security in full quarantine. That's very clear as to why you'd do that: because if you're positive, you don't want to be mixing and mingling with others in the managed isolation facility. If we don't test by compulsion on day three, how will we know that? Surely we've got a huge risk of day three people who aren't being tested, who may be positive, who are then infecting others in the managed isolation facility. How hard can it be to make day three compulsory just like it is for day 12?
