,,, who the hell told you that? Most people with that sort of info think New Zealand is a trademark on a pound of butter.
Jews in New Zealand... I can tell you that there aren't a whole lot of them here, but the ones I'm aware of are typical of what I know them to be - hard working, a love of business and they're not in Courts or on welfare. Send plenty more here, but keep the ones who tell you bullshit like that right where they are.
Which might provide some evidence that they are, um, not very welcome in those parts?
