Listening to the Prime Minister's answers in question time, I was absolutely convinced that she is on top of the detail, to an incredible degree, and I have absolute confidence in her, and in our senior public health officials, that they will move as quickly as possible to adopt any new technology or approaches that are going to help us. And so I don't doubt that saliva testing will be a thing, if it is the right thing to do. I was quite surprised at the vehemence of David Seymour's speech criticising the Government. It's a bit surprising to hear that, especially when I would say, by any objective measure, New Zealand is amongst the top four countries in terms of effectiveness and COVID-19 response. The Lowy Institute, based in Australia, recently put out a report at the end of January: out of 100 countries, New Zealand was ranked number one for COVID-19 response. Of course, that report also acknowledged that no country was perfect and that the top countries, including Taiwan, Vietnam, Thailand, Cyprus, and New Zealand, all had different approaches; no single approach was best, or that much better, than the others.
