Little patches of high-res content are starting to show up in Google Maps. So far we seem to have the North Shore of Auckland, a little patch of northern Waikato, and for some reason lots of the mountainous part of Marlborough.

This picture shows a bit of the Wairau River (in Marlborough) at maximum resolution. The top left part is what most of the country looks like, the rest is part of the new high-res imagery.
I like Google Maps very much indeed. I would like to be Google Maps when I grow up.
