Having your vehicle certified self-contained allows you to take full advantage of New Zealands most remote, beautiful and best of all FREE designated camping areas. A certified self-contained vehicle must comply with all of the NZS 5465 regulations and essentially be able to accommodate its inhabitants ablutionary and sanitary needs for a minimum of three days without any waste products being expelled into the environment.
