Yeah an absolute bolt from the blue, how can New Zealand ever prepare for the sudden and unprecedented invasion of multistory buildings.

Saw a comment on my local councils post of someone worried that the Tauranga CBD would look like Shanghai in a fews years "at the rate they're going".

Some of the most popular, picturesque tourist spots and residential locales in the world make NZs "high density" plans look laughably wasteful in comparison, and people are still tearing their hair out about it.
