It doesn’t have to be sold to NZ either. What if the other countries decide not to sell to you because they get severe supply controls to go along with their price controls? Because that is what is in the process of happening.
You say, sold ‘to’ NZ.
It is, as far as I can tell, manufactured there. By Pfizer.
NZ may not even have price controls, but I don’t know.
I’ve had pharma that was made in Turkey, too.
Maybe it’s like the internet. Customer demand treats intransigent nationalism like network damage and routes around it.
