If you are planning to buy a campervan and camp for free in New Zealand, you will keep hearing the words certified self-contained. Here is what they mean, in plain English.
The green certificate, in plain words
A self-contained van can carry everything its passengers need for a few days without using outside facilities. That means fresh water in, waste water out, a toilet, and a bin for rubbish.
When a vehicle passes the official self-containment check, it gets a certificate and a green warrant card. The card is displayed on the van so a council officer can see it at a glance. Travellers often just call it the green card or the green sticker.
Why it matters: freedom camping
Freedom camping means staying overnight in your van on public land without paying for a campground. It is one of the best parts of van life in New Zealand, and it can save you a lot of money over a long trip.
Here is the catch. Many councils only allow freedom camping in vehicles that are certified self-contained. Park overnight in one of those areas without a current green card and you can be fined.
With the certificate, a whole network of free overnight spots opens up to you. Without it, you are limited to paid campgrounds and the smaller number of places that accept any vehicle.
The 2023 law change, in one paragraph
The rules were tightened by the Self-Contained Motor Vehicles Legislation Act 2023. Under the current system, a self-containment certificate lasts up to four years. Any vehicle certified under the new rules must have a fixed toilet, not just a portable one stored in a cupboard. The green warrant card is the proof that a van meets the current standard.
What is physically inside a certified van
A certified van carries four things:
- Fresh water. A tank with a tap or pump, holding enough water for the number of people the van is certified to sleep.
- Waste water. A sealed grey water tank that catches everything that goes down the sink, so nothing drains onto the ground.
- A toilet. Fixed in place for vans certified under the 2023 rules.
- A rubbish bin. A sealable bin so waste stays inside the van until you reach a proper rubbish point.
Nothing exotic. The whole idea is simple: a certified van leaves no trace behind.
Every van we sell comes certified
Every van at Comfort Campervans is sold certified self-contained. The certificate and the green warrant card come with the van, so you are ready to freedom camp from your first night on the road. There is no extra process for you to sort out.
At a viewing we will show you the toilet, the water tanks, and the paperwork, including the expiry date on the certificate. You can read more about what happens at a viewing.

The certificate is not a camping permit
One thing trips up a lot of travellers. The green card proves your van is allowed to freedom camp. It does not tell you where.
Each district council sets its own rules about where vehicles may stay overnight, so the same van can be welcome in one town and fined in the next. The rules live in three places:
- Council signs. Always read the signs where you park. They are the final word for that spot.
- CamperMate and Rankers. The two apps travellers actually use. They show which spots accept certified self-contained vehicles, with reviews from other campers.
- Council websites. The official rules for each district, useful when you want to be completely sure.
We cover this in detail in our guide to where you can freedom camp in New Zealand.
