Room temperature fomites won't spread it if it has been > 2 weeks.   I would look at frozen items (specifically, frozen food boxes, or even potentially, frozen food itself).

I expect they are also considering animal to human spread.

Isn't it also possible that it was contracted by interaction with asymptomatic residents in NZ?  (And I get that it would have to involve multiple asymptomatic transmitters, but still).

Or has every person in NZ been tested (and continues to get tested)?
