There is a pandemic playbook, much of it actually written in the U.K. as well as refined by the experience of SARS. It was put into play by lots of countries with different regimes, cultures, geography and populations not just teensy weensy New Zealand
It’s not that simple. There were different plans. UK’s and many other countries was based on mitigating a pandemic flu. Other countries approached it like they had SARS from the start.
The idea of strict local/national lockdowns like in Wuhan and wider areas in China was controversial at the time (didn’t the WHO view it with suspicion?) and it wasn’t a straightforward global plan that obviously you do this if there’s a pandemic.
Teensy weensy New Zealand locked down in late March, the same as the UK.
The UK actually had 2 strategy documents.
One for dealing with a new virus, like SARS etc. Believe it or not, the ONLY strategy they listed was STOP the virus from leaving the origin country... like the UK has the power to force border control on another nation lol..
The other one, which is the one we followed, was a plan designed as you say to cope with a worse than usual influenza epidemic, in which it had been decided that stopping it was out of the question, so it was all about keeping everything running while the virus ran its course.
Lockdowns weren't controversial, they weren't even considered! Neil Ferguson ran a number of scenarios through his models back in 2011?, that fed into the government's planning documents. He considered various limited restrictions such as closing schools, limiting international travel as means to slow a virus down, but nothing like a full lockdown!
Back in early Feb I remember arguing with someone about dealing with covid. We both knew it was coming - at the time my view was that it was unstoppable - I couldn't see a western government doing what China had done. But then Italy imposed a lockdown (local) and that changed everything, because the fact that one of the very best healthcare systems in Europe had been overwhelmed in such a short timeframe meant "letting it rip" was absolutely not an option any more.
The UK SHOULD have learned from Italy, but we didn't. Instead we clung to the herd-immunity plan until well into April.
NZ is irrelevant - they did everything they needed to to keep the virus out. We didn't.
