Taiwan operates an effective home quarantine system (and 850 deaths for a 23m population). Why couldn’t NZ? There would be a lot more capacity that way.
I can't answer that in full because I don't know all the details, but one issues is that Taiwan captures phone location data in a way that has no precedent here.
I’m fairly sure anyone who wanted to abscond wouldn’t take their cellphone with them if that was the case. And yet the cases and deaths in Taiwan remain very very low for its population.
