Hillsborough is a suburb of Auckland, New Zealand. It is under the local governance of the Auckland Council. Hillsborough is a leafy suburb of 20th-century houses. The area is serviced by two shopping areas; Onehunga and Three Kings. The area is served by secondary schools Mount Roskill Grammar School and Marcellin College. History Since the mid-18th century, the Auckland isthmus has been within the rohe of Ngāti Whātua Ōrākei. The south-eastern Hillsborough area near the Manukau Harbour was traditionally referred to as Rangiaowhia, the name of a settlement and waka landing site south of Onehunga High School which was partially covered up by the construction of State Highway 20 in 1975. The name may reference the view of the cloudy sky above the high point of the Hillsborough ridge, Pukekāroro. The northern area of modern-day Hillsborough was known as Koheraunui, referencing the kohekohe trees which were once common in the lava forest landscape of the area, and was known for its kūmara (sweet potato) cultivations.

Pōtatau Te Wherowhero and Tāmati Ngāpora sold the land with the consent of Ngāti Whātua Ōrākei chief Apihai Te Kawau to English land-dealer William Hart in December 1844. The suburb was named for James Carlton Hill, who left land to the city for use as public domains in his 1858 will. The Pah Homestead (or The Pah) was constructed for James Williamson by Thomas Mahoney on the 313-acre estate Pah Farm in 1877–1879. Of plastered brick in the Italianate style it is based upon Queen Victoria and Prince Albert's house Osbourne House in the Isle of Wight. It was allegedly the largest house ever built in New Zealand and one of the most expensive. Following the failure of Williamson's business concerns after the stockmarket crash of 1886, the estate was progressively
