Hon CHRIS HIPKINS: It's important to remember that when it comes to our elimination strategy—so the testing that we are doing within the community and the testing that we are doing at our border—even a 2 percent difference in the efficacy of different testing methods can have a very significant impact. Unlike countries who are dealing with mass numbers of COVID-19 cases, where 2 percent is actually relatively immaterial in the grand scheme of things, to New Zealand 2 percent can be the difference between having a big cluster of cases develop and not.
