Hon CHRIS HIPKINS (Minister for COVID-19 Response): In answer to the first part of the question, no. As I told the member last week, we have moved from discussing a joint decision-making framework with Australia to discussing more of a unilateral approach to decision making, and those discussions continue. Issues that we're working through include understanding the circumstances that could lead to a suspension of green zone travel on either side of the Tasman; what we would do with those whose travel is disrupted by the suspension of a green zone; testing requirements that may be put in place on either side; Australia's current exit visa restriction, that prevents Australians travelling to New Zealand without a visa; the state-by-state differences in decision making in Australia; decision making around expansion to other countries outside of the safe travel zone and who would make those, and whether New Zealand would have any input into that process; and contact tracing system interoperability, in the event that we needed to do contact tracing for people who had been in one country, and were then identified as being more at risk after they had travelled to another country.
