There are a number of defences that a Government has against a viral outbreak. One of them is tracing. I see Ayesha Verrall joining us in the Chamber. Her excellent report set out a gold standard that the Government should be able to trace 80 percent of cases end to end in 96 hours, with up to 1,000 cases. And yet we heard from the Prime Minister just now that it's taken 15 days to not trace 518 cases in the South Island—at the other end of the country, from the outbreak, 518 people. They still haven't managed to return negative tests on 518 people in 15 days. So the South Island must remain in isolation, or a wait-and-see stage, which is truly crippling to people's commercial and personal business every day, not to mention education, not to mention healthcare.
