Established in 1927, the school mainly serves the eponymous suburb of Takapuna and the entire Devonport Peninsula.

[1] The foundation stone of Takapuna Grammar was laid on 6 April 1926[3] with the school opening officially in 1927.

The school retained the Auckland Grammar Lion and the motto "Per Angusta Ad Augusta" ("Through endeavour to greatness").

The main block, which was initially built in 1927 upon the school's establishment, was described by local MP Maggie Barry as an "appalling sight."

In Years 12 and 13, students can continue with NCEA levels 2 and 3, or complete the International Baccalaureate (IB) Diploma Programme.
