New Zealand

First timer here, I want to make a map and use it to teach myself some more skills. I am ok with GIMP and think I can get my head around the xml. I am wondering if anyone has seen a New Zealand map made? Is it a good map to use? I am from New Zealand and have seen a lot of the maps floating around here are mainly countries and thought it would be a good a place to start as any.
My idea is to base it off:

With maybe a more kiwi flavour... using the Maori designs:

and a few icons of New Zealand to keep the interest up. Thinking the gameplay would be pretty simple with about 30-40 territories.
Is this worth trying my hand at for a first map? I am willing to put in the time to set it up right and would enjoy the constructive ideas that flow around these parts.
Thoughts?
