Rt Hon JACINDA ARDERN: Actually, we already are undertaking saliva testing for our most high-risk areas—our most high-risk places being, of course, our facilities where we bring in those who are positive for COVID. So the Jet Park in Auckland is a place where we're utilising saliva testing and have been for a little while now, and doing the same, of course, in Christchurch and Wellington. The thing that I just wouldn't mind taking a moment to share with the member: as it's been explained to me, saliva testing is not as accurate as polymerase chain reaction (PCR) testing—the nasal swabs—which is why we like to use them, because unlike other countries that like to undertake general surveillance and have a tolerance, we need to pick up an individual case. At the moment, in order to validate the process, we need to have individual saliva tests sitting alongside individual PCR tests, so they can't be pooled, which means they take the same amount of lab capacity time and, I understand, processing as you would for PCR testing. The other issue is that to validate it to ensure it's a robust regime, we have to have some positive cases going through it, and because New Zealand has such low levels of COVID, that makes the validation process a little more lengthy. You could, I'm told, skip that, but I'm not sure anyone would want that situation. So, broadly speaking—forgive the long answer—we of course are in favour; we just want to do it in a way that it adds something.
