Growing up in New York City in the 1980s, I became a big fan of graffiti - especially the old subway cars, before the MTA started making them hard to paint. So I'm always happy to see cool graffiti, murals, etc... that make a city more interesting.
The three larger cities we spent time in on this trip - Wellington, Invercargill, and Dunedin, all delivered great street art (although I got the fewest photos from Dunedin).

Wellington Shark mural by BMD
The banner image above is portion of a very large mural near the waterfront in Wellington. Created by artist BMD, the mural was part of a campaign to ban the practice of shark-finning in New Zealand (an effort which resulted in new laws, but there are still some issues). It was still up at least as recently as 2017 (flickr).
Here's an interview with BMD.
