First, for culturally sensitive, I do realize that this is a traditional stance that has been stylized for the statue, which lies at the entrance to Karekare Beach in the Waitakeres, just west of Auckland. It is a Pou and symbolized the manawhenua, or spiritual guardianship of the beach area to be enjoyed and respected by all. It IS a gorgeous piece of carving, and very typical of the sophisticated artwork of NZ's first nations.
That said I could not refrain from a whimsical thought that is was engaged in the famous (or infamous) dance of Spanish origin. Doubtless anthropologists will see this and immediately anticipate a doctoral thesis on how the cultural exchange occurred...
