The roll is approximately 340 with an average Year 9 intake of about 80-90 pupils drawn from the four local contributing Primary Schools each year (Granity School, St Canices School, Westport North School and Westport South School).

​Buller High School provides a safe and secure environment for the general education of pupils in Years 9 to 15 following National Curriculum Guidelines. We also provide technology education for the Year 7 and 8 students from our local primary schools.

Pupils are encouraged to value knowledge, to develop independent learning skills and good study habits, to improve skills of judgment, decision-making and communication, and to take pride in high personal achievement.
​
They are encouraged to develop respect for others; to improve self-esteem, self-discipline, tolerance, and to co-operate with others in the interest of learning. They are also encouraged to participate in a wide variety of sporting and cultural pursuits, to develop individual skills and talents to their fullest potential. The school recognises its unique role in the community and continues to encourage staff, pupils, parents and the local community to become involved in achieving these goals.
