One thing NZ doesn't have is castles. We have one, apparently, it's Called Larnach's Castle in Dunedin which is more of a mansion and gardens and so it is not what I would call a castle- I was disappointed going there as a kid as I as expecting it to be castle.
However, just north of Oamaru is a place called Riverstone Kitchen which is the only South Island winner of NZ restaurant of the year. 10 years ago it was a paddock, now it is a restaurant, cafe and giftshops and soon they will have a castle. Not sure if it is to ward off Norma invasions or what but it will look pretty impressive once finished. It will be faced in the local Oamaru stone (limestone) and comes compete with moat!
