Thanks for bringing this to my attention, I've lived here all my life and I didn't realise this had been passed.

"A new offence will now be created of sending messages or posting material online that were intended to cause harm, and did so."

Really worrying, that. If I were to say, "NZ's National Party government is really shitty, and everyone reading this should not ever come to NZ, ever!" and people listened, does that mean I just caused... harm to a political party? It's so vague and stupid it's not funny! Ahhhhh!
