UK quarantine (so-called) arrangements are a complete joke.
Give your address at the airport, travel home by public transport (pick up some shopping on the way) then comply (or not) with self-isolation!
Returning to NZ requires two weeks in a hotel (self-funded) and no leaving the building.
I can imagine the outcry if returning holidaymakers were told they had to spend two weeks in a hotel, self funded, no leaving the building.
They would expect the government, i.e. the taxpayer, to pick up the tab.
