Mangakino is a small town on the banks of the Waikato River in the North Island of New Zealand. It is located close to the hydroelectric power station at Lake Maraetai, 85 kilometres (53 mi) southeast of Hamilton. Its population in 2001 was 1257. The town and its infrastructure are administered as the Mangakino Pouakani ward by the Taupo District Council
In 1896, (after 40 years of resistance) the Crown acquired the Wairarapa Lakes from Ngāti Kahungunu and in 1915, gave in return land in middle North Island, land known as part of the Pouakani Block. At that time the land where Mangakino lies today was described as native bush and pumice wastelands, barren, unoccupied and unfarmed. In 1946, as the Karapiro Dam neared completion, workers were to transfer to the next dam construction site – 'Maraetai I', near Mangakino. The Crown, under the Public Works Act, reacquired a portion of the unoccupied Pouakani Block alongside the Waikato River to build a “hydroelectric station” and a temporary township, Mangakino, was established to house the hundreds of construction workers needed. The town was only ever meant to be there on a temporary basis until the completion of the proposed dams.
