Having a Certified Self Contained Vehicle does not automatically make you a responsible camper, the responsibility is on the campers themselves, but having self certification certainly opens up your options for freedom camping and makes your travels that much easier.
Many local and regional authorities now expect many motorhomes, caravans and campervans to be certified as self-contained in order to stay at reserves and designated freedom camping areas.
Your vehicle must have been suitably and correctly set up for self-containment and meet the requirement of the NZ Standard.
NZS5465:2001 incl. amendment 2.
In general the vehicle must be fit for habitation.
