I do just want to highlight this because, actually, it's come up just in the last 48 hours again with the case that's in the media today about the person who left New Zealand and arrived in South Korea, where they got a positive result there. That was from a rapid test, and those rapid tests are internationally recognised as being less reliable than the PCR tests. We have been in this boat once before with someone who left New Zealand, arrived in Singapore, and got a false positive off a rapid test when they arrived, and the PCR test highlighted them to be negative, which is one of the reasons why if we see any people leaving New Zealand and getting a positive where they arrive, we ask automatically for a PCR test to be taken, because that means that they're being tested at an equivalent level to what the test would be if they were in New Zealand, and that gives us better data, thus far. It will be interesting to see what the case in South Korea highlights in the next 48 hours if we can get a PCR test done there. But the only other case that I'm aware of, it highlighted that it had been a false positive that they received in the rapid test.
