Great Photos Dave!
If you are keen on Art Deco in particular I would recommend a trip across the Tasman to Napier NZ. The city was hit by an earthquake and subsequent fire that totally destroyed the downtown area. It was all rebuilt in the 1930's and is arguably the best example in the world of a predominantly art deco environment. It is, because of this, a world heritage site.
While the city has expanded, the planning requirements still demand that new building in the area have to be finished in the Art Deco style. Every February they hold an Art Deco weekend where many people hire suitable attire and visitors come from far and wide with period cars.

The area also has great wineries, and the weather is generally nice and warm. I hope this helps.
