Hon CHRIS HIPKINS (Minister of Health): Sequential testing is the best answer at the moment. There is no foolproof solution here. Obviously, a lot of work is going on in New Zealand and around the world on testing regimes and on how we can get faster testing results, testing results that don't require being taken off to a lab—more instant test results. The advice that I've received so far is that the rapid tests results are even less reliable than the polymerise chain reaction (PCR) tests. Those tests that we're getting at the moment are quite reliable. They're the most reliable that we've been able to identify so far. Of course, we're keeping an eye on what the testing solutions are that might be available here and around the world. Where good solutions emerge, of course, we'll aim to be fast adopters of them. But at the moment, one of the best things we can do is test more frequently in order to eliminate false positives.
