History.
The area was purchased from three local Maori Chiefs by The Wiiliams family in the late 1830s, the farm being called Penrose after their home area in Cornwall, England.
The railway line between Auckland and Onehunga running through Penrose (now known as the Onehunga Line) was one of the first Government funded railways in New Zealand, being opened in 1873. It was built by the Auckland provincial government. 
The new motorway and the move of industrial and manufacturing occupations out of older centres like the Auckland CBD soon started a boom in the Penrose-Mount Wellington area. Industry also successfully lobbied for state housing to be built close by, to provide the new area with a supply of labour. To this day, the area remains almost exclusively industrial, with a mix of run-down areas and newly established sites.

Despite the low local population, Penrose is the site of the former Penrose High School, which in 2008 renamed itself One Tree Hill College, to shed the 'industrial' associations of the name.
