We need rules.
How we enforce them, is another story.
Freedom campers travelling throughout Northland are going to get greater guidance on where they can and can't park. The rules are slightly discriminatory toward modern-day hippies. If you are cruising around Northland in an old Kombi van, or a converted Hi-Ace, you can't stay in the same places as someone in a motor home with its own loo.
Having chosen to visit New Zealand because of its Lord of the Rings scenery, racial harmony and friendly "come one, come all" peoples, in Northland we will judge how hospitable we are toward you by the manner in which you go about your daily business on holiday.
Yes, dear tourist, your flash loo opens up greater opportunities than someone who is guerilla toileting.
