New Zealand is part of the "Commonwealth Realm" (as is Canada, and 14 other nations). That means that Prince Charles could one day be New Zealand's king -- and hence the king of all Maori. The Maori presented Prince Charles with that head dress -- it would have been unbelievably rude for him to not wear it.

Your Head of State (your elected, term-limited, Monarch) often dons native head gear, when he ventures from his Washington DC palace, to mingle with his subjects.
