This cable is compatible with the AutoTap interface:

Its only $19, however the shipping from NZ would be about $40 overnight or around $5 by post.
Maybe AutoTap (www.autotap.com) still sells replacement cables. I know that when they did, it was around $19 also. If you can get it through them then the shipping would only be a few dollars.
Or you can make one yourself by purchasing an OBDII cable end here:

The wiring pinouts are described on page 3 of this document:
