Its an updated version of Auckland 2005, with the Airports ONLY from the 2005 version, and has had most of the static aircraft stripped out of it, making it a little easier on frame rates.
Never had the "sinking wheel" problem with that one, but did with the 2005 version.
It was made to fit into Real NZ Auckland City, and also for the 20m RBE mesh, whereas the 2005 version was not.
