Vaihu is a small fishing harbor on the southeastern coast in which there is a large cistern in the form of a double slope. The lateral wall, which in the past defended the fresh water from sea water intrusion, is today totally crumbled. The Ahu (platform) of the Vaihu sector is called Ahu Hanga Tee. It is 74 meters (242 feet) long and 4 meters (13 feet) wide with walls made of worked stone. It is one of the most complete Ahu-Moai complexes with 8 Moai (statues) and their Pukao (headdresses) scattered and, in some places, broken. In front of the Ahu are the remains of a village.
Ethnographic notes indicate that these residences were occupied by an elite made up of high ranking people from the major lineages of each territory, representing socio-political power and associated with ceremonial activities, such as the Paina, which was held in the circular plazas in front of the Ahu-Moai.
