I'm sad to say I don't really like any of the options. Whether we need a change or not aside, it would have been nice to have a bit more diversity with the finalists. But I guess there is only so much that we can have on the flag that would be relevant.
The Union Jack in the corner of our current flag is a little too "colonial" for some people's tastes; also, the NZ flag and the Aussie flag are nearly identical at the moment. There is a very active social media campaign for the "Red Peak" option to be included in the options; so far it looks like it won't happen, but I love this design : http://m.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11508844
The PM has relented and now Red Peak is one of the choices :
It was in the top 40, but it didn't get a lot of attention until people started noticing the lack of variety in the final 4 (which some people have called "what colours do you want with your fern? Or would you rather go for the possum's bum?")
