I wouldn't say it's nothing, It's just nothing very visible to the general public. With the direct flight ban and screening taking place in Sydney/Singapore/Dubai and more there isn't much more that we can do at the border that wouldn't increase general anxiety. Considering the crap we're seeing so far it's more than justified to take a cautious escalating approach so as to not cause more public harm
Yes, but if you are a NZ national/resident, and fly in, you are allowed. If thats via or from an infected country, including mainland China, you are asked/suggested/advised to self isolate. To me, the Government is doing nothing, we ask the citizens to do it, if they can be bothered.
Don't follow what you mean by "the crap we're seeing so far it's more than justified to take a cautious escalating approach" NZ is taking a cautious approach, at best, and even thats complimentary. We are not taking a Keep It Out approach which is our official stance. Its more like lets not upset anyone, inconvenience anyone, and cross our fingers. Now, if we got a few infected people inside our borders, and lets say for example, the self isolation infected 3 others each, so we have a dozen plus infected. Who would get the blame then?
