The simple question is this: at Logan Park High School in Dunedin are the 150 staff and students who are being tested there—all symptomatic or are some of them asymptomatic? If the answer to the question is the former, then we should shut down the city, and if the answer to the question is the latter—fantastic. What that means is we are going to get ahead of the curve, because what we know from overseas experience is that asymptomatic carriers of the virus become symptomatic spreaders of the virus and if we know who those people are, we can stop the spread. I was critical yesterday in congratulating the Government on the $500 million health package, but worried that we're still nickel and diming this, that there are mixed messages with our health professionals who are being told by the Prime Minister they have the discretion, but being told by the Director-General of Health that they've got to stick to the programme, which is the 14 March guidelines for testing.
