I don't think I saw this message until now. I'll use it to let you have my contact details.
My home phone is (03) 383 2244 and mobile is 021 115 3695. If you dial from outside NZ, then of course it's 0064 3 3832244 or 0064 21 1153695. I don't have a smart phone, so emails only reach me if I'm checking my computer.
If you do get time to fly in Christchurch, I have kites for every possible wind condition, so you don't need to worry about that.
You seem to have several whole or half free days, for instance in Dunedin, Auckland, Wellington, Bay of Islands and Rotorua. All of these, in the right conditions, should give you opportunities for KAP, but I realise that most of your time will be spent just sightseeing. I have a friend in Dunedin who might be able to give you a few pointers in where to KAP - he's mildly interested in KAP himself, but more of a kite-flier like me.
