Dr SHANE RETI (National—Whangarei): Thank you, Madam Chair. Thank you to the Minister for that—that would be very useful. He mentioned that we know more now than we did then around the coronavirus response, meaning several months ago, and that's probably true, but I would contend that around asymptomatic testing, which came up in Estimates—the Minister said, "Then there's an element which is asymptomatic testing, which is looking across the whole system,". And if I look back on 4 March, Minister David Clark stood in the House just over there and said to the House that coronavirus is not transmitted by people who are asymptomatic. How could that be true when expert modelling for the ministry a week earlier had told him that at least 48 percent of positive tests could be asymptomatic?
