New Zealand has lifted almost all of its coronavirus restrictions after reporting no active cases in the country. The country first went into lockdown on 25 March, setting up a new four-stage alert system and going in at level four, where most businesses were shut, schools closed and people told to stay at home. The move to level one comes ahead of time - the government had originally planned to make the move on 22 June, but it was brought forward after no new cases were reported for 17 days.

What were the crucial elements of this success, and what lessons can be learned?
