Self-Containment for Campervans in New Zealand: Rules & Certification

A self-contained vehicle can hold its grey water (waste from sink/shower) and black water (toilet waste) for a set period (usually 3 days minimum) and has a fixed supply of fresh water. In New Zealand, the standard is NZS 5465. Certification is shown by a green warrant card — the old blue warrant expired on 7 June 2026 and is no longer valid. Under the current system, green stickers have no legal status — enforcement relies on the warrant card and the national register. Blue vs green self-containment explains the history. For freedom camping you need a current green certification. Only certified vehicles can freedom camp in areas that require self-containment.

The standard specifies: a fixed toilet (portable toilets are no longer accepted for new certifications under the 2024 rules), minimum tank capacities, secure fittings, and a warrant issued by an authorised inspector. Vehicles certified before the rule change may have different setups; check the warrant expiry and any council bylaws.

The green self-containment warrant card is issued after a certified inspector checks your vehicle (fixed toilet, water tanks, etc. to NZS 5465). It has an expiry date (often 4 years). You must get re-certified before it expires to continue freedom camping where self-containment is required. The old blue warrant expired for all vehicles on 7 June 2026 and is no longer accepted anywhere. See blue vs green self-containment and how to get certified under the green system; ensure you have a current green warrant card. Keep the warrant card in the vehicle (display is required for enforcement).

The self-containment system was overhauled from December 2023, moving certification under the Plumbers, Gasfitters and Drainlayers Board (PGDB) with a national register. Green certifications require a fixed toilet (not portable). The transition period for old blue warrants ended on 7 June 2026 — since then, every vehicle must hold a green warrant card to freedom camp where self-containment is required, and portable-toilet setups no longer qualify. Always check the latest NZS 5465 and council rules.
