>>Additionally they have put in a 14 day quarantine (self administered after travelling anywhere in the UK by public transport) plan for overseas visitors. That would include visitors from Covid free New Zealand.

I once had to get a chest xray for TB screening required to visit an African country. At the time, that country already had numerous TB cases while NZ had just 3, in one ward in Greenlane Hospital. Meanwhile that country also denied any AIDS cases mostly on the grounds that they have no homosexuality; on arrival I found 9 kids on a pediatric ward with the disease and if the kid has it, probably so does the cis mother. The intervening 30 years has deprived me of any sense of wonder or surprise at the ineptness of politicians and officials perched on their moral high horses.

As for current quarantine: during lockdown, NZ allowed in dozens of film workers for the next Avatar movie. From COVID hotspot LA. They were quarantined in a Wellington hospital at taxpayer expense but apparently mingled freely with other guests who insist they were not warned. This sort of anecdote along with ministers or officers of health flouting the rules after scolding that to do so will result in zillions of deaths, led to public relaxation of social distancing in the last week or two of lockdown.
