The first was that outbreaks are to some extent inevitable. Systems break down and its impossible to make them foolproof.
The other is that there needs to be preparations for opening up to the world. The New Zealand economy depends on international trade and it isn't feasible to be closed forever. They are also honest enough to say a vaccine may be some years away so there needs to be a clear plan on how to achieve contact with the world that is fit for purpose.
At no point do they say the New Zealand should have open borders.
International trade can still occur in a covid world, with the current system NZ has setup. One of the main things that will affect NZ with this virus longer term, is international tourists, and the knock-on effects that that causes throughout the economy. But things such as selling milk power and food to the rest of the world, and us buying in products, can all absolutely still occur in the current situation, as it is now. Likewise with covid eliminated, it now doesn't stop people buying and selling houses to one another, which was a major part of NZs economy. Likewise local tourism. If people do need to travel overseas for business reasons, then quarantining will need to be factored in at at least one end, once things do open up a bit more, and most NZers have returned back. eg If someone is travelling to UK, then because NZ is covid free, then they don't need to quarantine when they arrive. But when they return, they will. That cost would have to be factored into their trip, but in many cases will be a business expense. Whether this lasts 2 years, 5 years, or longer. We have been spoilt by cheaper international travel and unimpeded free travel for decades, but things change.
If systems are robust, with belts and braces, then they should be watertight. We were assured that the borders were watertight. Maybe that was an error for them to say that, based on what has happened. But there can always be processes to make sure they are, and then belts and braces to mop up any leaks. So far it has worked, and things have been improved , and holes plugged. But there could be the day in the not too distant future, when we get our first community case, especially with the increased testing, which they are now ramping up again. eg you may not find cases, if you don't test for them.
What could NZ have done any differently, that would have been better than the current situation? From what I can see, any other solution would mean NZ would be in a worse position than we are now, especially as we are now essentially living a pre covid life in NZ, and our internal economy and businesses can operate as normal, minus international tourists and students.
