Mairehau High School

Mairehau High School is a co-educational secondary (year 9-15) school in Christchurch, within the Canterbury Region, operating in the state sector, with 407 students on roll, and an Equity Index of 510. The school has been open since 1961.

With 407 students on roll, Mairehau High School is a large school — larger than about 74% of New Zealand schools.

The school's Equity Index is 510, which is above the national average of 463. A higher Equity Index signals greater socio-economic need in the school's community — schools in this band receive more targeted government funding and support. The gap of 47 points is substantial enough to matter when comparing schools.

The largest group is European at 70.3%, with a meaningful Asian community at 17.2% — a mixed but clearly led roll.

On the isolation index the school scores 0.15 (low isolation) — this measures how far students travel and how accessible the school is, not how good it is.
