What is wrong with you people?
Why do you want NZ to have a flag which look like a cheaply made corporate logo?
I thought it looked great, actually. Not too minimalistic like the standard three-color European flags, but not too busy either. I would have preferred Option E though.
I too dislike the existing NZ flag, and while the new suggestion was not too busy, it still looked more like the logo for a travel company more than a national flag, it simply lacks dignity (something the existing one do have, even if it's ugly as f**k)
