One Tree Hill College

One Tree Hill College is a co-educational secondary (year 9-15) school in Auckland, within the Auckland Region, operating in the state sector, with 1,479 students on roll, and an Equity Index of 466. The school has been open since 1955.

With 1,479 students on roll, One Tree Hill College is a very large school — larger than about 97% of New Zealand schools.

The school's Equity Index is 466, which is close to the national average of 463. That means the roll faces a broadly typical level of socio-economic challenge compared with schools across Aotearoa.

The roll is genuinely diverse: no single ethnic group dominates, with Asian at 40.2% and Pasifika at 29.4%. Diversity of this kind is common in urban New Zealand schools.

On the isolation index the school scores 0.2 (low isolation) — this measures how far students travel and how accessible the school is, not how good it is.
