Hi,
If you want the best picture (monitor-quality) on a TV, then a SCART cable is the way to go. I assume that TV's in NZ have such connector. I also assume that you are in NZ and that the pinout of the connector will be a world-wide standard.
You can search the net for the cable. You can try:

I have built this cable and it does work, however the resistors happened to be necessary in my case (so this could be your case too). I have been using it in an A4000. Also, bear in mind that 23-pin connectors might be difficult to source.
Good luck!
