Oh goodness, have you been suckered into the 'illegal gardening' joke?
>A man set himself on fire to protest the horrible family court system
That man's wife had left him and taken their kid to Japan. I'm not sure what kind of non-horrible family court system you imagine NZ could have, which would be able to direct outcomes in the Japanese system.
As for family court, you know in NZ it is a frequent but macabe quip: it is easier to kill your wife than divorce her? People say that for a reason, and people don't just light themselves on fire so easily.
I live in NZ and I've never heard anybody say this. You should think twice before repeating horrible comments on the internet. Particularly comments about violence against women.
Also, I grow a number of avocados at my NZ home. They are not illegal.
