There is now a 95% chance COVID-19 has been eliminated in New Zealand, according to our modelling, based on official Ministry of Health data.
As of June 4, New Zealand has had 20 consecutive days of zero new cases, with only one active case remaining. The last new reported case of COVID-19 was on May 15 (going by the date the case was first suspected rather than later confirmed).
This still leaves a small chance of undetected cases, and we know that COVID-19 is passed on at superspreading events.
New Zealand is now preparing to relax its COVID-19 restrictions to alert level 1 from as early as next Wednesday, which would end physical distancing and size restrictions on gatherings. But our modelling suggests removing limits on large gatherings will increase the risk of a very large new outbreak from 3% to 8%.
