Mana College was established in 1957 as the first college in the Porirua Basin. It is a state, co-educational school from Year 9-13. Mana College participates in Gateway, and also encourages adult students. The roll currently comprises 63% Māori, 20% Pasifika, and 15% New Zealand European.
Mana College is situated in Takapuwahia, and draws primarily from Titahi Bay, Elsdon, Ranui Heights, Porirua City Centre and parts of Porirua East, although students from other areas are welcome to enrol. The College benefits from the effects of the ocean and the harbour and is in the heart of the Ngati Toa runanga. The college is well supported by local iwi.
The local community is characterised by ethnic harmony, strong sporting involvement, noticeable influence from churches and secular groups and a strong sense of identity and resilience.
