And this takes us to another major problem and failing with this Government's COVID-19 response: it's inability to work with the private sector and augment its response to COVID-19 with better technology. First they told us they couldn't have saliva testing because it wasn't accurate—well, actually, first the Prime Minister didn't understand what it was. But then, once we solved that problem, they started to say it's not as accurate. And then Janet Pitman from Victoria University of Wellington said it's just as accurate. Saliva testing is as accurate; it's just faster and less inconvenient to the person giving the sample. That's the result they've come to. And then they say, "Oh, but it doesn't have quite the same sensitivity, depending on the particular stage of the infection." Even if that was true—and it appears now that it's not, but even if that was true—there's a trade-off between the cost, the inconvenience, and the frequency of testing. If you want to make sure that you actually catch COVID-19 with a test, perhaps a less sensitive test might actually catch it if you apply it more often than a less sensitive test that can't be applied as often because of cost or because of the inconvenience and people's reluctance to have it.
