But what is it that makes our quarantine-free travel bubble with Australia safe? Well, the overarching consideration is that we have a partner we can trust. We know the Australians have good testing systems and strong reporting of COVID—we can rely on their data. We know they use accurate testing methods. Their response is a very strong one, and it has closely followed ours across the last year. We also have a framework for dealing with outbreaks. This includes how we would respond should there be any cases in Australia, and it mirrors the alert level system we have in New Zealand, so people planning travel can consider that there'll be roughly similar responses to a case in Australia to the types of responses we've mounted to cases here. For example, cases that are clearly linked to the border where reliable contact tracing information is quickly obtained would not necessarily require disruption to travel. However, those that are more complicated, where it's not clear and may reflect community transmission—i.e., the case is unlinked to the border—may require a short pause in the travel bubble. Similarly, travel may be suspended if there is a larger outbreak or multiple unlinked cases and a longer period of time is required to understand what is going on.
