It was more good news for New Zealand on Thursday, as the Director-General of Health announced no new COVID-19 cases and 12 new recoveries.
There are now just eight cases of coronavirus still active here - and if those cases don't infect any others, we could see that figure drop to zero as soon as next week.
But while Dr Ashley Bloomfield's announcement indicates total elimination of the disease could be on the cards very soon, you might be surprised to learn that 14 significant COVID-19 clusters remain open.
Adding to the confusion for some Kiwis is that four clusters were closed earlier this month, then reopened; and that the others still haven't closed, even though just two of 14 remaining clusters are composed of active cases.
The reason for this is disarmingly simple, however, and it all relates to a subtle change the Ministry of Health made a couple of weeks ago.
On May 14, Dr Bloomfield announced that the ministry would be altering its definition of a closed cluster after receiving new advice.
Previously, the Ministry of Health had considered a cluster closed if two full incubation periods - the equivalent of 28 days - had elapsed since the last case was notified. The change means two incubation periods now need to have elapsed since the last case completed their isolation period.
That meant four significant clusters which had previously been defined as closed were reopened, as the ministry decided to retrospectively apply the criteria.
It also means it's possible to have less active COVID-19 cases than active clusters, which is what we saw for the first time on Thursday.
Even though just two significant clusters are still composed of active cases - seven at an aged residential care facility in Auckland and one from group travel to the US - the new definition means just two are closed.
These closed clusters are a 30-person community in Auckland and a 14-person community in Christchurch, according to the ministry's website.
Speaking to media earlier in May, Dr Bloomfield says from a public health point of view, the change makes it easier for public health unit staff to retain appropriate health measures like isolation while they continue to learn all they can from the different clusters.
From the public point of view, however, the ministry says it will mean "only minor changes to the information on our website".
