When I was in high school we read a book called Smith's Dream (by C. K. Stead). It was a fascinating book following a man who finds himself caught in an insurrection in New Zealand. It presents a battle between the military and a rebel force. The rebel force had camps in the Coromandel, well-armed with safe houses, code words and the like. It was made into a movie Sleeping Dogs (Sam Neill's first big movie). Oddly enough I chose to rent and watch this just recently, and as of today it is reported that police raided the Bay of Plenty (and other places) for paramilitary groups!
I hope this unravels to show exactly how this has come to be and what was to be.
