I've uploaded my whole end-to-end Process of creating the KMLs 7.7MB Zip file, if you want a copy just PM me :).
It needs Java to run as I am using Saxon and mdb2sqlite. It's pretty much written for Windows but would be very easy to port over to Linux due to most of it being java based.
Also done a new extract out for the new 2Degrees Sites in Wanganui and Palmy.
KML and Google Maps
Also updated my Blog with the latest and greatest from RSM as of 20 June, which is the date of the file.
Enjoy!
