I find this opening line from the Guide entry to be very interesting:

New Zealand is situated the same distance eastwards from Australia as London is from Moscow

My rough calculations based on this extraordinary description, some dabbling around in a geography site (http://geography.about.com/gi/dynamic/offsite.htm?site=http://www.indo.com/distance/) and assuming that Zild is that far east of the eastern coast of Oz, place New Zealand about half way between Perth and Alice Springs.
