Kaiapoi · Canterbury Region
Kaiapoi High School is a co-educational secondary (year 9-15) school in Kaiapoi, within the Canterbury Region, operating in the state sector, with 1,044 students on roll, and an Equity Index of 465. The school has been open since 1972.
With 1,044 students on roll, Kaiapoi High School is a very large school — larger than about 95% of New Zealand schools.
The school's Equity Index is 465, 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.
82.5% of students identify as European, so the school has a strongly homogeneous roll. Students of Asian descent make up 8.1%.
On the isolation index the school scores 0.38 (low isolation) — this measures how far students travel and how accessible the school is, not how good it is.
Total roll recorded: 1,044 students. Percentages are calculated from the 2026 roll census and may not sum to exactly 100% because of rounding and students who decline to state an ethnicity.
