I think that's it - the west coast (both USA and Canada) locked down earlier because we had travellers from China when the news was mostly focused on how it was effecting China. The east coast of both countries weren't screening as thoroughly as we all were when everyone went out and returned during spring break (and earlier). It's not that we don't have travellers to/from Europe on the west coast, but we were already aware and worried about it by the time Europe started getting sick.
Seattle's first case was Jan 20. Vancouver's was Jan 24. San Francisco was the first US city to lockdown. I think it's just that the west coast was ahead of the rest of North America when it came to taking it seriously. Presumably, the same was true of NZ - the kiwis may have had their first case later, but they took it very seriously right away.
First case was Feb 28. It crept up to 5 for a week or so.
Early testing focused travellers and people exposed.
Once they found two cases of community spread we were in lockdown 2 days later. Community spread being they couldn't tie it to travellers/foreigners.
We don't have very many ventilators per capita and a lot were already in use.
PM had friends in UK tell her to lick down now and Italy was a thing.
We're increasing testing numbers and getting declining cases. Government forecast 4000 cases we've got 1200 iirc.
Before lockdown they already quarantined old folks homes and people started self isolation already.
I called my wife's Aunt an idiot for going on cruise early March, she got as far as Australia before she got in a boat and everything fell apart. Managed to get a flight back in a day or two things really went to custard.
Last year, currently around 10 degrees Celsius.
August 2019
Do weather doesn't seem to make a difference. Queenstown is our hotspot, Alpine area not overly warm atm.
Smaller scale but tourist traps and transit hubs same pattern as north.
