Not sure if you look at the digitalspy.co.uk forum for SCD or check out YouTube, but someone has started putting up videos from series 3 of DWTS NZ.
Try searching for YouTube for DWTS3 and that should bring up the NZ videos. If you go to the Brendon Cole thread on the digitalspy forum board for Strictly Come Dancing, you will find the links to the videos - I think they start getting listed around page 606
