Certified Self-Containment Certification & Upgrades
Are you ready for the new freedom camping rules? New Zealand’s self-containment regulations have completely changed. Under national law, the old blue self-containment warrants are officially no longer valid. From this point forward, only vehicles carrying the new green warrant certification are legally recognised as self-contained.
At MJs RV Service Centre, we make navigating this transition simple. Whether your vehicle requires a plumbing retrofit to meet the strict green warrant standards or you just need an authorised inspection, our expert team in Waitākere is here to get you fully compliant and back on the road.
How We Get You Ready
Bringing your vehicle up to the new national standard doesn’t have to be stressful. We can inspect, modify, and finalise your certification right here in our workshop.
Step 1
Initial Assessment & Consultation
Get in touch with us to discuss your current setup. We'll check your tank sizes, venting, and toilet style to identify exactly what upgrades are needed to clear the green warrant hurdle.
Step 3
Official Inspection
An authorised officer will thoroughly inspect your freshwater, wastewater, ventilation, and fixed toilet systems to ensure they comply flawlessly with the Plumbers, Gasfitters, and Drainlayers Regulations.
Step 2
Modifications & Upgrades
If your caravan or motorhome needs modifications, our workshop team will handle everything - from installing permanently fixed cassette or composting toilets to upgrading freshwater and greywater storage (minimum 4L per person, per day for 3 days).
Step 4
National Register & Card Issue
Once passed, we log your inspection details directly into the official New Zealand Self-Contained Motor Vehicles Register. After the government levy is processed, your official green warrant window card is issued, giving you total freedom to explore public land.
