I reckon the kiwi is a good choice for a national bird, because it is very distinct shape. When you see a silhouette of a kiwi there is no question what it is. There is no argument that tui and kokako are more beautiful birds but they have no distinct shape to them, sure they have obvious markings, wattle, etc which distinguish them from other birds, but no other bird is the same shape as a kiwi. So you can draw a stylised kiwi in one swift movement
and everyone knows what it is.
