I think it is. The current flag does not present a distinct identity that represents New Zealand. The Southern Cross could apply to many southern hemisphere countries, the Union Jack is a symbol another country, and the similarity of colour & layout mean many confuse the NZ & Australian Flag.

This site is intended to stimulate debate about the New Zealand Flag. We want all New Zealanders to ask whether the current flag represents our country as we see ourselves today? Can we improve it?
Does it portray the image we want to give of New Zealand internationally?
Most importantly, does it inspire us?
