The Government has taken a cautious approach when it comes to opening up the trans-Tasman bubble. What we didn't want to see is the border opening and closing willy-nilly without New Zealanders knowing where they would stand in the event of events happening on either side of the Tasman. We made it clear from the beginning that our preference was for a joint decision-making framework. That was what the Australians indicated they wanted initially. Then, they moved on to one where they indicated that they would prefer to keep a unilateral decision-making framework, where each country made its own decisions about whether the green zone would open or close, depending on how they wanted to respond to events on either side of the Tasman. We adapted to that approach.
