Hon CHRIS HIPKINS (Minister for COVID-19 Response): We did put in place additional safeguards for people returning from Australia. One of the most obvious was that everybody coming back from Australia needed to have a negative COVID-19 test before they were able to come into the country. Some of those states in Australia, when we did that amnesty week, had no active cases in their community. So the risk was low, but the risk was growing. Subsequent events over the last week have demonstrated that that's the case. We have also put, for Victoria, where there was a slightly elevated risk at that point, a requirement that people need to self-isolate on return and get another negative test once they've come back to New Zealand. So I think that there were appropriate risk mitigations in place.
