mattwnz: ... It doesn't make much sense, when workplaces and schools are a risk in themselves of bubbles merging. I do wonder how many cases there have been in level 4, from workplaces, where people have got it from other staff members.
I found these article very good, and I do worry complacency under level 3, which we won't get some evidence of, until close to when level 3 is due to end.
This guy really knows his stuff, and I think if NZ does eliminate it, the country can owe a lot to him for speaking up like he has, and the government listening, because he is probably one of NZ leading experts on this stuff

New Zealand needs to urgently look at wearing masks in public - expert
Also how long have we been waiting for advice from WHO as to whether it is recommenced to wear masks in public? What is the delay. I think their use in enclosed spaces is a good idea, because if someone has it and they sneeze, then the mask will help to contain this.
Fully support this and have from the start, regardless of the (convenient) claimed lack of evidence for effectiveness. The experience of several Asian countries clearly suggested that at worst wearing a mask is not worse than not wearing one as WHO, MOH, et al have suggested at times.
And evidence is starting to accumulate in favour of masks, including a link I posted five days ago in the data analysis thread (#2465318). eg.
"Masks led to a notable reduction in the number of RT-PCR–positive respiratory droplet and aerosol samples for patients with either coronavirus (in respiratory droplets, from 30% to 0%; aerosols, 40% to 0%) or influenza infection (respiratory droplets, 26% to 4%; aerosols, 35% to 22%); there was no meaningful reduction seen with rhinovirus infections."
That is for coronavirus, the reduction was from 30% down to 0% in respiratory droplets and 40% down to 0% in aerosols. Maybe there is no proof of effectiveness but a precautionary approach would support encouraging there use on public transportation and in enclosed areas, or supermarket queues etc.
Despite the fall in new (local) cases here in in NZ we are still a long way behind the likes of S. Korea, Hong Kong, and Taiwan. Taiwan new local cases per capita are still two orders of magnitude lower than NZ local cases. See plot in #2470393
