Can my child go here?
This school has an enrolment scheme, so a place is not open to every address. How enrolment zones work
Loading zone map…
Zone boundaries shown here are approximate. Ministry of Education data warns these boundaries do not have high spatial precision and can place neighbouring addresses on different sides of a line. This is not a confirmation of enrolment eligibility — always confirm directly with the school. Zone geometry also does not reflect enrolment priority rules (siblings, special character categories, ballots) — it shows the mapped boundary only.

The practical things this school states on its own website — the hours, the uniform, the term dates, and how children get there. These are the school’s own words, not the Ministry’s record and not ERO’s.
Quoted from this school’s own website, as we read it on 13 August 2026. A web page carries no date of its own, so that is the day we read it — not a statement that any of this is still the case. Each line quotes the words it came from.

What does the school say about itself?
Quoted, not summarised. Every school describes itself well, so this is here to be read as the school’s own case rather than as a finding — and a school that states nothing simply has no row.
Quoted from this school’s own website, as we read it on 13 August 2026. A web page carries no date of its own, so that is the day we read it — not a statement that any of this is still the case. Each line quotes the words it came from.
- International students

One Tree Hill College welcomes International Fee-Paying Students and has a long and very successful record catering for their academic and pastoral needs.

What is on offer beyond the classroom?
The sports, arts, clubs and groups this school names on its own website. Not a complete list of what any school offers, and not a count — a school that names more here has written more down, which is not the same as doing more.

What did ERO find?
The Education Review Office reviews every school and publishes what it finds in full. We quote ERO’s report here, section by section, in ERO’s own words and order, and link to it. We do not summarise a report, pick a line out of one, or turn one into a score. How ERO reviews schools

- Board assurance
- The board attested to all areas (15 April 2024)
A board assurance statement is the board’s own account of whether it took all reasonable steps to meet its legal obligations, on the date shown. It is not ERO’s finding. ERO reports separately, in the same report, on any non-compliance it identified during that process.
The board assurance report of 15 April 2024 carries no actions-for-compliance section — the section ERO uses when it names non-compliance it identified. That is what this report contains; it is not ERO saying it found none. Other reports ERO holds for this school may say something different.
The roll ERO recorded, and when
ERO writes a roll into each report it publishes: a count taken for that report, on the day shown, by the review team that was there. The Ministry of Education’s current roll for this school is 1472 — the figure at the top of this page, and the one to use for how big the school is now. These are a different measurement by a different body, so they will rarely agree, and a difference between them is not a change in the school.

This is ERO’s report of 15 April 2024 — “Profile Report April 2024” — section by section, under ERO’s own headings, in ERO’s own order. Nothing is summarised, shortened or reordered.
Background
This Profile Report was written within 6 months of the Education Review Office and One Tree Hill College working in Te Ara Huarau , an improvement evaluation approach used in most English Medium State and State Integrated Schools. For more information about Te Ara Huarau see ERO’s website. www.ero.govt.nz
