Pahukini (many drums) is a heiau is located on the slopes of Kapa'a and at one time overlooked the site of an ancient adze quarry. Said to have been built by 14th century Tahitian Cheif Olopana it hs also been listed as being named Mo'okini (many lineages) and also Makini (contraction of make kini or many deaths). These last two names suggest this heiau was designated as po'okanaka (human head or skull) and functioned as a a luakini where rulling chiefs proayed and human sacrifices were offered. It measures approximately 120 x 180 feet with an adjoining 32 x 38 fee structure on the north wall.

For many years the heiau was neglected and rock quarrying in the 50's created a 200 foot cliff and caused one side of the structure to collapse. It was later filled in with landfill from the nearby dump. It was placed on the Historial Register in 1972 but remained neglected and surrounded by grading activity through the late 80's when it was rededicated. Today it is located on city land behind a locked gate on the site of the now closed Kapa'a Dump. Access is possible by advanced arrangements only. Joint curators of the site are the Kailua Hawaiian Civic Club and the quarry company Ameron, HCD.
