I think that really needs to be looked at, because we're making the case here that it works and that we knew back in September, in fact, that it was going to be effective. I'm reading here from Official Information Act documents: "Saliva testing can be used for screening in certain populations, such as border workers who require regular testing." So the question of daily-ness—if you want to call it that—wouldn't seem to be in question. Also—and I raised it with the Minister—testing saliva is approximately as sensitive as and less invasive than nasopharyngeal swabs. I understand there's some conjecture around that, and other medical experts will offer a view into that. But what we were told on 10 August is "Saliva testing as a routine option for surveillance testing is well over a month away." OK, then maybe in October—that was in August. Let's go a month away: "No, it's still coming in September.", and in October we were hearing it may be at least two months away. It just seemed to get away on us. Now, I understand part of that, because on around about 10 August was around about the Americold coronavirus case, so I understand a little bit how that stretched out, but not why we're so late.
