Mother nations? How archaic and patronising!
It is nobody's business but the New Zealanders, and those who have commented do not seem impressed. Not that the politicians are likely to take any notice of that!
Don't New Zealand have a national wizard? someone wise and whacky.........I nominate Nearly sane.
Please, at least get your terminology right.
Wizards are denizens of fiction!
If the inclusion of the word (wizard) is a shot/pun/joke at my being a witch - all witches are witches male or female.
Oh and don't call a male witch a warlock - it means traitor or oathbreaker.
If it was not please ignore the preceeding.
