Rt Hon JACINDA ARDERN: Again, keep in mind that saliva testing that we've contracted to be provided is doing exactly the same job as the nasal swabs, albeit, obviously, through collecting in a different way. So it's not as if by not having that scaled up, somehow we have lost something. It is an extra, additional tool that gives some choice to staff members around the way that they're being tested, because we totally understand—and anyone who has been swabbed will know—how uncomfortable it would be to have that done on a regular basis. So the reason for the numbers they've had is simply for uptake in the way it's being rolled out, but we are looking at using it for returnees as well, so I expect those numbers will only continue to increase. As I say, we're contracting separately for border testing as well.
