Seddon School is a co-educational full primary school in Seddon, within the Marlborough Region, operating in the state sector, with 127 students on roll, and an Equity Index of 440. The school has been open since 1883.
With 127 students on roll, Seddon School is a medium-sized school — larger than about 32% of New Zealand schools. Its rural setting typically means smaller class groups and a close-knit community feel.
The school's Equity Index is 440, which is below the national average of 463. A lower Equity Index signals less socio-economic need in the school's community than the national norm.
96.5% of students identify as European, so the school has a strongly homogeneous roll. Students of Pasifika descent make up 3.5%.
On the isolation index the school scores 0.93 (high isolation) — this measures how far students travel and how accessible the school is, not how good it is.
Total roll recorded: 127 students, from the 2026 roll census. Percentages may not sum to exactly 100% because of rounding and students who decline to state an ethnicity.
