I was up in Wanaka for the last Wannakite, snow farm was where I went to kite the entire time and there was tonnes of easily accessed land to kite on from just off the car park ( looking back towards Wanaka) though we had to pay the snow farm guys abit for each session. just stay off anything that looks like a track!
I bought my kite, an 06 Ozone frenzy when I was over there. Glad I got a foil because all the guys on c kites were strugling, bow kites weren't as bad. just comes down to relaunch and landing, foils rock (on snow). Note, It was areal struggle finding a kite on the south island, I think there was only 1 store, cant remember the name. Chriss Gebbie ended up posting 1 to wanaka for me. Some C kites had a 5th (or 6th!) line attached to the back of the kite (opposit end of the centre bladder where an old school 5 line it attached) and that seemed to help.
Get a freestyle board (twin tip style) and SOFT BOOTS! I bought hard boots cos I spent so much time on the slopes snowboarding regularly, but If I was only gonna kite I would have gotten soft boots, my calves were all bruised by the end of the day kiting.
Flow bindings or the like, where the heel support folds down as opposed to the top straps folding off would hav helped so much too (I realised to late), you'll see why when you start. I've heard they are not as solid, there wouldn't be much in it though, and for how much easier they make it i wouldn't care!
I've still got my Frenzy and probably wont be using it anytime soon if you are looking for one to buy. 12m 06, go me moving before anyone else out there and you're pretty much parasailing once your airbourne
