NZ have surprised me by opening travel with Australia a lot sooner than I had expected - when very few of both populations are vaccinated.
This makes me think the pressure to reopen from businesses and the economic point of view is stronger than the pressure to remain closed from people who're fearful. It suggests they may reopen full international tourism sooner rather than later too. It lends weight to those expecting it to be this year rather than next year.
Although it seems to me the wheels could very well still come off...
