Nearly 30,000 people have signed a petition demanding the New Zealand government allow a fifth entry in the contest for a new national flag.Red Peak, designed by Wellington resident Aaron Dustin, was on the long list but did not make the final four.The finalists were revealed to widespread disdain last week, with many saying said they were too boring, too corporate or unrepresentative.But PM John Key has already said no to adding Red Peak into the contest.Mr Dustin has made the case that his flag design is simple and meaningful.
