A friend taught for a few years in NZ and on a few Pacific islands and said that there was a terrible culture of domestic violence. He told me of working with this “lovely bloke” and being invited round to his house for dinner only to witness the “lovely bloke” backhand his wife over a minor mishap with dinner or some shit. He said in one place it was fairly common to see multiple boys in his class at any one time with black eyes from being beaten by their dads, and that that was just considered “normal”.
