Local councils also often have specific bylaws about skateboarding in public places like town squares – for example:
Wellington Consolidated Bylaw 2008, Part 5: Public Places
Wellington City Council bylaws allows skateboards and skates to be used in public places (like urban parks and squares) unless there’s a sign there saying otherwise. But you have to show reasonable consideration for other people there, and make sure you don’t damage council property (bench seats for example).
Auckland Council Public Safety and Nuisance Bylaw 2013, clause 6(1)(c)
Auckland Council bylaws say that skateboards and other skaters in public places can’t be reckless or ride in a way that could be dangerous, intimidating or a nuisance.
