As far as Covid 19 goes, a comparison between New Zealand and Britain adjusted for population suggests thousands of people here probably owe their lives to the government's actions in this regard. I don't have the actual figures at hand but everything I have seen indicates that we have got away with an unusually low infection and death rate unmatched anywhere else. Surely that suggests that the authorities have done something right?
You can whinge all you like about the things they got wrong. I for one am extremely grateful for the things they got right.
Some of your facts are plain wrong. Taiwan in terms of death rate and early control/handle on the disease has been significantly better than us. That's just one example that one can find without trying very hard.
"Flawless" has an established meaning. People need to decide whether they are going to just rant and rave and say whatever they want so long as it's favourable to their own side. If that's your style, go for gold. But you are no longer discussing anything meaningfully the moment you head down that path How can some of the things I cited be better? In respect of some of the issues I've identified, I don't think it's too much to ask for a government department to obey the law, especially over a matter as sensitive as someone wanting to spend his father's last days with him. The MoH should be raked over the coals for the Christiansen case and people sacked for it, yet the government did little. The OIA business? How about they just obey the law again? In terms of handling the lockdown breaches, look at Australia and their massive on-the-spot fines. We should have done the same thing.
These things aren't that hard to get right. OTOH, getting them wrong sure doesn't invalidate the other achievements by the government. But unless you are Homer Simpson or a political hack, simply ignoring them is reality denial.
