Manukau, also known as Manukau North to distinguish it from other areas, is a locality in the North Island of New Zealand.

Manukau is part of the eponymous 9,280 acres (3,760 ha) block, with some of it held as Māori freehold land (collectively owned land). The Manukau Block includes the Herekino Forest.
Manukau is the site of the Whinau Pah and a trig station.
Issues of ownership and sales of the Manukau Block led to a 1908 Native Land Commission report that recommended an end to private sales; however, issues continued and local Maori went to the commission later that same year with claims that settlement and agricultural sites had been included in land sales despite an agreement to exclude such sites. Further sales continued in 1914 with Auckland buyers purchasing land for agricultural purposes. These purchases were also contested and in 1916 the Native Land Court with the court ruling on the return of 105 acres (42 ha) and compensation for Maori who had not agreed with the sale of land. In 1933 83 acres (34 ha) was subdivided as part of the Māori Land Development Scheme.
In 1926 the Manukau Native School was established. Two years later the school had a second teacher. The school initially operated out of an old hall but a purpose built schoolhouse and teacher's residence were constructed in 1934.
Manukau locality covers 75.94 km2 (29.32 sq mi). It is part of the Herekino-Takahue statistical area.
