(Clay Sinclair's fern on the present flag’s blue background)
A two colour flag is the cleanest design choice, and the blue and white make a strong contrast. 35 countries have red blue white, only 2 full blue and white. Using colours from the present flag recognises a proud tradition of service.
Internationally, now is not the right time for a national black flag, (though of course our sports, military and others can and should put ferns on black as they have for so long).
Our stylised native fern may symbolise many aspects: the taonga of our tangata whenua, "the koru unfurled and mature", our history, our sport, the natural beauty of New Zealand, and more.
For a flag, truly "less is more", so the strong choice is just the fern alone, without distractions. It makes a clean, timeless design for our young people, and a long future. Clay’s fern is better for a flag than the more complex official Fern Mark it resembles.
Among all the world's flags, this is an utterly distinctive flag, for all New Zealanders.
