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
Silverstream School is a co-educational contributing school in Upper Hutt, within the Wellington Region, operating in the state sector, with 500 students on roll, and an Equity Index of 393. The school has been open since 1924.
With 500 students on roll, Silverstream School is a large school — larger than about 81% of New Zealand schools.
The school's Equity Index is 393, 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 70 points is substantial enough to matter when comparing schools.
The largest group is European at 62.8%, with a meaningful Asian community at 20.9% — a mixed but clearly led roll.
On the isolation index the school scores 0.22 (low isolation) — this measures how far students travel and how accessible the school is, not how good it is.
Total roll recorded: 500 students, from the 2026 roll census. Percentages may not sum to exactly 100% because of rounding and students who decline to state an ethnicity.
