Rt Hon JACINDA ARDERN: If the member wishes to put on notice specifics around when contracts are awarded with private labs, he should feel free to do so, and I'd be happy to come back to the House with specific details. But to come back to the principle of the question—which is, essentially, are we bringing alternative methods on stream?—the answer is yes. We've been using it at our managed isolation facilities. Of course, the member will know, because we've talked about this in here, it's been sitting alongside the nasal swabbing. What we've been having discussions around is, if we're going to increase the frequency of testing, how can we use saliva as the replacement so that we aren't causing that ongoing discomfort and sometimes damage? Important to note that the saliva testing we've been using is still a polymerase chain reaction. So whilst labs with extra capacity and so on can process them quickly, it's not an instant test, but it does have the same level of accuracy that you would expect, and that's really important for our programme.
