The Rathgar Rd side of the school was the Vitasovich's Ideal Vineyard and further land was previously an orchard and vineyard owned by the Platts. The grounds of the school grew grapes for wine and fruits, such as apples for the orchard.

The school was opened on the 3rd February 1975 with a roll of 183, third form students.  
In October 1974 the school was  informed, apologetically, that permanent buildings would not be ready for at least a year, the school made do using nine relocatable buildings connected by covered walk ways. The old wine cellar and wine vats were still present and were put to good use with the wine cellar converted into a gymnasium and assembly area, while the wine shop became the canteen, and the old farm house on the land was made into the staffroom and reading room.

By 1977, the school had grown to 700 students, and several modifications were made to improve the school and provide more facilities to students and teachers. The Gym and fields were complete and construction had begun on B Block.

On the last day of term 1 in 1994 ISC Te Whare Rangiemārie opens with 3 students. A first of it's kind; the only unit for physical disabilities for secondary school aged students in West Auckland. Originally named the 'Unit for Physical Disabilities' this unit was purpose built in the old library building with specialist staff - a physiotherapist, occupational therapist and speech language therapist.
The unit began with 3 students and 6 staff members, by the end of 1994 there were 6 students and the role quickly grew.

Today, the Inclusion Support Centre/Te Whare Rangiemārie is a bustling unit of 50 students achieving goals such as achieving NCEA levels and winning medals at the special olympics!

2015 saw our very own Whare, sitting proudly near the front of the school. Named Whare wānanga, Te Waipuna o te Matauranga . A blessing at dawn including performances, and breakfast for 1000 people ensured the official opening and blessing a special day for all.
