Dunedin (New Zealand)

The city of Dunedin is the capital of the New Zealandic province of Otago, and second most populated city of South Island.

Its flag, whose use is restrict to city council and other authorized bodies, is the banner of arms, similar to this:

The green zigzag line refers to Otago's mountains and valleys, and its three tops refer to the Mounts Flagstaff (yes, a vexillologic mountain!), Swampy and Cargill. The ram (wool and mutton) and the sheaves (cereals) represents some important economic activities of the region. The castle is inspired in the famous Edinburgh Castle, present on the flag of the Scottish city of Edinburgh, as "Dunedin" name was took from Gaelic name of Edinburgh, Dùn Èideann, and even some Dunedin streets, etc. are named after Edinburgh counterparts. The ship represents the first Scottish immigrant ships, being the foundation of the town related to Free Church of Scotland.

My proposal, using a geometrical approach, is the following:

On bottom, the same zigzag lines of coat of arms, representing the mountains, valleys and the bay (where there's a port), while the blue and white is supposed to form, together with bottom part, an allusion to the Scottish saltire, a reference to Edinburgh and the Scottish founders of the city.

I like the result, aesthetically, but I fear that, maybe, it's a too radical departure from original flag. Anyway, differently of council flag, this flag could be freely flown.

Comments are welcome. Feel free to comment.
I'd like to wish an excellent 2014 to all, and give thanks to all the support during 2013.
