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.

What would the day look like?

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.

Please use alternative streets adjacent to the school for student drop-offs and pick-ups. - Buses do not call early on days when school finishes early.

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.

In their words: Kei konei mātou,
ka poipoia ō mātou puāwaitanga
ka ea hoki ō mātou wawata
We bring ourselves,
together we are nurtured to thrive
and realise our aspirations.
International students: Accepted, as statedOur new cohort of 30 International students started their Onslow experience with a large school Pōwhiri on Monday morning.
Voluntary donation: $350 per student, $500 per family, 2026the Board has decided to raise the school donation to $350 per student and $500 per family.

What is on offer beyond the classroom?

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

Reports ERO holds: 5
Last reviewed: 6 December 2022
Latest report: Te Ara Huarau | School Profile Report
Report type: Profile report
Board assurance: The board attested to all areas (6 December 2022)

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 6 December 2022 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 1187 — 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.

August 2017
1240
Counted while ERO’s review team was at the school. Education Review Office, report of 20 November 2017
June 2014
1249
Counted while ERO’s review team was at the school. Education Review Office, report of 19 August 2014

We draw no line between these. Each was counted for its own report, years apart, by a different review team, and a roll moves between reviews for reasons none of these figures record — so the difference between any two of them measures nothing.

What ERO wrote in its latest report

This is ERO’s report of 6 December 2022 — “Te Ara Huarau | School Profile Report” — 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 ten months of the Education Review Office and Onslow 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
Context
Onslow College is a Years 9 to 15 urban co-educational school in Johnsonville, Wellington. The school’s vision for its learners is that they: bring themselves| kei konei ahau , grow| kia puāwai and thrive in the paths they choose| haere whakamua . A new principal began in 2018. Three new senior leaders have been appointed since then.
Onslow College’s strategic priorities for improving outcomes for learners are to:
ensure that all aspects of the wellbeing of ākonga are supported so that they can grow and thrive
create positive opportunities for Māori and for all ākonga to be biculturally confident citizens
collaboratively design an innovative curriculum that supports equitable learning pathways
create an environment that nurtures all ākonga .
You can find a copy of the school’s strategic and annual plan on Onslow College’s website.
ERO and the school are working together to evaluate the effectiveness of their teaching and learning based on indicators of best practice from research.
The rationale for selecting this evaluation is:
the college wants to improve outcomes for Māori ākonga
to ensure all students have a strong sense of belonging to Onslow College to support engagement
the college has already begun building culturally responsive teaching practice across the school
the board and school community are committed to honouring Te Tiriti o Waitangi .
The school expects to see:
all Māori learners thriving
a combination and use of all the tools that are effective in achieving the school’s vision
a shared understanding and evidence of what best practice is at Onslow College
the school’s vision and values underpinning all aspects of the school.
Strengths
The school can draw from the following strengths to support it in its goal to be effective Te Tiriti o Waitangi partners.
The commitment of the board and college to honour Te Tiriti o Waitangi as full treaty partners.
Staff who are active Te Tiriti o Waitangi partners and who are keen to learn and reflect this in their teaching.
The college’s developing partnership with Te Ātiawa Taranaki Whānui to support the college in its quest for equity.
The cultural knowledge and skills of the college’s kaiako Māori that will help guide other kaimahi .
Strong college middle leadership which supports continual improvement towards the college’s vision for its learners.
Where to next?
Moving forward, the school will prioritise:
senior leaders and teachers collaborating to develop and present an overview of the Onslow College effective teacher profile, underpinned by key research findings
the development of a shared understanding of how restorative practices, universal design for learning, learning conversations and data (learning information) underpin the effective teacher profile
visible and clear curriculum development focused on equity.
ERO’s role will be to support the school in its evaluation for improvement cycle to improve outcomes for all learners. ERO will support the school in reporting their progress to the community. The next public report on ERO’s website will be a Te Ara Huarau | School Evaluation Report and is due within three years.

ERO reviews a school every few years — around four years between reviews is the usual cycle — so an older date here reflects where a school sits in that cycle, not how it is doing.
