The .nz cc-tld is broken up into several 2ld's .co, .net, .org, .gov,
,.gen, .maori, .school, .iwi, .geek, etc.  You can't buy a 2ld, you must
buy 3ld's.  Thus I own "meta.net.nz", and someone else owns
"fish.net.nz" etc.  This isn't unheard of in the cc-tld space, it's also
used in the uk and australia for instance.  Keeping track of which
cc-tld's sell 2ld, and which only sell 3ld's is fairly tricky.
