Figures on this page come from the New Zealand Ministry of Education school directory export dated 1 September 2026, with roll and ethnicity recorded at the same snapshot. Always confirm enrolment, zoning and fees directly with the school. About this directory
Mt Cook School (Wellington) is a co-educational full primary school in Wellington, within the Wellington Region, operating in the state sector, with 303 students on roll, and an Equity Index of 414. The school has been open since 1874.
With 303 students on roll, Mt Cook School (Wellington) is a large school — larger than about 61% of New Zealand schools.
The school's Equity Index is 414, which is well below the national average of 463. A lower Equity Index signals less socio-economic need in the school's community than the national norm. The gap of 49 points is substantial enough to matter when comparing schools.
The roll is genuinely diverse: no single ethnic group dominates, with Asian at 52.1% and European at 27%. Diversity of this kind is common in urban New Zealand schools.
On the isolation index the school scores 0.06 (very low isolation) — this measures how far students travel and how accessible the school is, not how good it is.
Total roll recorded: 303 students, from the 2026 roll census. Percentages may not sum to exactly 100% because of rounding and students who decline to state an ethnicity.
