sorry you did say it wouldn’t work in the Uk thus the question from myselfYou can stop the spread of the virus by a severe lockdown perhaps even eradicate it if you lockdown early enough. New Zealanders can only leave their homes to walk, buy groceries or see a doctor. Even if eradication succeeds its borders will have to remain closed to the rest of the world to keep the virus out. That will decimate the tourism industry which is its largest source of foreign exchange earnings.
