TVNZ on demand works no problems for me and I use it daily. I normally fire it up on my PC and cast the tab to the Chromecast once the video starts playing.
That's exactly what I was trying to do, without any luck. Maybe it's the changes I made to my DNS that are causing problems. dns4me allows you to turn different services on and off, and I think I remember I seeing settings for NZ TV (although why anyone would want to want NZ TV from overseas I'll never know!)
