The halls of the United Nations echoed with singing and chanting during the colorful and lively traditional Maori ceremony to welcome UNDP Administrator Helen Clark. The event, called a powhiri (pronounced poor-fee-ree), began with the thunderous sounding of a conch shell and a Maori warriors dance, and ended with Helen Clark, the former Prime Minister of New Zealand, and her Maori delegation pressing noses with senior UN officials in a hongi.
