It's a worry that it has re-appeared in NZ after 101 days without any community cases, as they have been a beacon of hope and inspiration for countries like ours that also have the potential to eliminate community cases as well... but flights are still coming into NZ with returning citizens that have the virus, so maybe there was a breach of traveller quarantine over there as well.
(the news tonight had said that two of the people worked at a cold-storage warehouse that imports organic goods, which is being tested... hopefully that isn't the source, as it will have a massive impact on frozen imports in every country, which could see countries like ours blocking all frozen and possibly refrigerated imports, which includes a lot of processed foods, and ingredients to a lot of foods, that are in our grocery stores)

I think it is good to see drastic action being taken straight away when there are only single digit cases that have an unknown source, because... why wait until there are 300 new cases per day before the only action that stops the spread is undertaken (like they did in Victoria), because once numbers get that high, deaths are guaranteed. The same is the case in NSW, slowly increasing, and won't go away while everything is open. It just hasn't been as rapid as Victoria because they were more prepared with the expected outbreak, as the Melbourne outbreak was unexpected and spread a fair bit before it's extent was realised. But the best outcome any country has done without a lockdown is just a slower increase, which will still accelerate when daily numbers reach a certain amount that is more than resources can handle and more unknown sources grow.
A drastic action might draw in criticism, which the media will highlight and make worse, but waiting until X-amount of daily cases, will see deaths that will also draw in criticism from community sources and media.
You're damned if you do and damned if you don't... but at least one option will see little or no deaths, and a quicker recovery of the economy.
