Dr SHANE RETI (National—Whangarei): Is there any position, then, for exit testing from New Zealand, whether or not this comes up positive from South Korea? Is there any work being done—modelling, any thinking—around exit testing, bearing in mind we do that for Samoa already? You have to have a medical certificate within three days showing you are PCR negative to go to Samoa—so it's not new, this precedent. But is there any work being done towards that being rolled out more fully as we depart, as an exit test?
