Interesting that the NZ person who's got it doesn't appear to have travelled anywhere, or have any close contacts who have travelled either.
So if they can't find a link, then that means there have to be others in New Zealand who are wandering around with it, symptom free and undetected, that this person caught it from.
So NZ is done then. It's over for them. The ultra harsh isolation from the world has done nothing but lose them massive tourism opportunities and massive TV filming plans (Amazon just moved Lord of the Rings from there). Even if Jacinda successfully manages to contain it this time by making everyone stay indoors, they can, and will, just have another undetected outbreak at any time.
It seems like some people in charge in Australia are absolutely desperate to turn it back into a penal colony?
