Here is a local article, you might find interesting, where the privacy commissioner has not been informed, yet, a USA organisation is getting New Zealand departments to sign up to USA laws for liability etc.
Plus other ramifications you can clearly identify from the article.
New Zealand past a private tort law in 2017 but that only covers some administrative concerns and doesn't go far enough leaving your body cam usage in some legal gray area(s).
Problem starts in the awful EULA. Even here in the US this EULA would face considerable pushback in certain states so I am surprised it hasn't been challenged here. Otherwise this appears to be a powder keg waiting to happen.
