25MBFS2004/FSX Dunedin Photoreal Scenery, New Zealand. This area covers the Dunedin Peninsular and city center. Photolayout by David Williamson. Autogen by Ian Warren and Robin Corn.
Found it at Flightsim.com today, search for 'dunedin'.
Its for FS9 but works fine in FSX as well. Great fun flying around looking for places I know.
Photos are old as motorway isn't complete but look much better than the default. Goes all the way to Dunedin Airport.
