Prime Minister John Key has said the current flag is not representative of modern New Zealand. He also believes it is too similar to Australia`s, but has admitted that polling indicates most New Zealanders would rather keep it.
The Flag Consideration Panel received 10,292 entrants to its nationwide design competition. Not all were entirely serious, though some of the rejected designs - including Laser Kiwi - gained something of a cult following.
Four designs were on the shortlist announced in September, but there was criticism that they were too similar or uncreative.
Three featured a fern design and the fourth the curving koru Maori symbol.
After a social media lobbying campaign, the government changed the rules so a fifth design - called Red Peak - also made the final cut.
To help people make a decision, the five flags are being put on display across the country.
Sets of flags are being given out free to communities who have five suitable flagpoles to display them from, so the public can see them in "real-life situations".
