Hey guys, welcome to Diatribe! These forums are a bit quieter than they used to be, as a lot of people have migrated to the facebook.
As Cat said, nzlarps and whatislarp are good places to start. If you want to get involved, I'd suggest Crewing a campaign game (basically you get given a range of roles to play, and you are providing with the costumes and props needed), or attending a convention, both are great ways of getting a feel for the hobby (esp if you have guardianship requirements). They're both relatively low-cost and low-effort ways of getting involved, and are immensely fun. Some regions also do short one-off games which are worth looking out for (Wellington in particular has quite a lot of these, I am lead to believe).
Feel free to ask questions too We're a friendly and diverse bunch.
