EDIT: I'm very confused as to why the confusion over AUS/NZ border.

AUS is on target to eradicate it like NZ, even if they can't as confidently say they have as high chance of succeeding.

If they succeed, great, we reopen.

If they don't, we don't.

It's all contingent on how the future plays out.

NZ's tourism will recover much faster by closing our borders & eradicating it since domestic tourism is half of the tourism industry.

If we opened up borders like impacted countries might with each other, then their tourism will not recover to pre-covid levels because again - travel insurance usually doesn't cover pandemics.

I'm 100% sure our tourism will have a much higher bounce from having freely moving domestic citizens not afraid of getting covid-19, than if we were under social distancing measures with open borders as an impacted country.
