A flag, like a national anthem, should be a representation of unity and togetherness and should bring a nation together. The maori confederate flag is by nature a message of divisiveness and as such should not even be considered.
This year being the 100th anniversary of Gallipoli whilst not any particular significant number in our years as a country, is inordinately important in our nationhood. New Zealanders, almost without exception, see Gallipoli as a birthing point of ourselves as a nation.
So we should be looking for something that unites us all. Some options show a variant of the Union Jack. I say we either keep it just as it is or remove it altogether.
Canada back in the mid-seventies went through a similar process. They chose a radical design that was widely criticised at the time. But now the Maple Leaf is synonymous with their identity.
To my mind we already have that symbolism firmly in place. Wherever and whenever our troops deploy ANYWHERE, they do 2 things as soon as they land. The first is to raise the New Zealand flag.
The second is to place a large and prominent Kiwi symbol outside the front gate.
