> During level-4, the R value is clearly lower than 1.0 meaning the infection shrinks

Delta is a different beast.

Here in Australia, Victoria managed to get the Reff rate down to ~0.75 during their OG outbreak last year with a strict lockdown. Delta has an R0 that is multiples higher than the OG strain so the same lockdown would not get it below 1. You can look at Victoria's current outbreak for evidence of this.

Now that doesn't mean NZ can't beat it. A part from Auckland, the population density is very low and as long as compliance is high you might be able to just about get it back down again; especially if you manage to keep it out of large households and essential workers.

I just wouldn't base my expectations on what worked last year as Delta is quite a different game.

Also worth noting that peoples' behaviour is very different this time round compared to a year ago. A lot more people are flouting the rules or at least coming up with creative ways to see their friends while technically not breaking the law. After 200+ days, everybody's just sick of it.

The framing of New Zealand's approach as "working great" is also very highly opinionated. My NZ colleagues are all starting to get sick of this approach, and even the ones that fully support it are realizing that having no international travel and a couple of 6 week nationwide lockdowns every year is not a viable long-term solution.

If you look at how far NZ has gotten in regards to overcoming the virus, it's clearly very far behind most of the world. It's done a good job so far of reducing the harm caused directly by infection, but in many ways it's just tried to lock itself into a time bubble in early 2020. The world is starting to move on, and NZ has put itself in a rather bad position of having to try and catch up. The longer it sticks with this approach, the harder it's going to be.
