The four rooms in the main block of the school were first used in the third term of 1957 as a side school of Titahi Bay School. The children were those who would attend Titahi Bay North School when it was established as a separate school.
The school opened as Titahi Bay North School in February 1958 with eight classrooms. The school was officially opened in March of that year by the Hon Philip Skoglund MP, the then Minister of Education (1957 - 1960) in the Nash Government.
In the early 1970s Rooms 11 and 12 plus three relocatable classrooms were also in use, along with the 8 original classrooms.
