In case you are not aware Napier, on the east coast of New Zealand's north island, was all but destroyed by an earthquake in 1931 and 256 citizens were killed. The town was rebuilt in the Art Deco style, popular at that time, and is now considered to be second only to the Miami area South Beach, with well preserved Deco buildings.
By the early 1990s it was realised that the town had an important architectural style and serious preservation and restoration began.
I have found that some of the more interesting examples of Art Deco are often to be found within commercial and industrial buildings.
link, David Thompson shows you some marvellous lead light windows from Napier, including some from the Rothman's building. I can assure you, you will like at least some of the windows.
