The Double Grammar Zone: what it covers, and how to actually check an address

The Double Grammar Zone is the area where the enrolment zones of Auckland Grammar School (boys) and Epsom Girls' Grammar School (girls) overlap. Live inside it and your children are entitled to enrol at both schools. Entitled means the school must take them, not that you can apply and hope. For many Auckland families that single fact matters more than how many bedrooms a house has.

Epsom sits at the heart of that overlap. It's the single biggest reason the suburb holds the values it does.

One thing first, and the rest of this page exists to serve it. Each school decides its own boundary, and those boundaries change. Everything below is general guidance. The exact address you're buying should be confirmed with the schools, in writing, or you shouldn't rely on it.

Looking for the zone map? We don't publish one, and you shouldn't trust anyone who does. Each school draws its own boundary and publishes its own map. Only those two count. Auckland Grammar's zone map and street list, and Epsom Girls' Grammar's zone map and Home Zone Address List. Open both, because a home can be inside one zone and outside the other. If the maps leave you certain, you are done. If they leave you unsure, the section below sets out how we would resolve it, and why the school is the only answer that counts.

What is the Double Grammar Zone?

New Zealand state schools that have more applicants than places run an enrolment scheme, which is the formal set of rules deciding who gets in. Each scheme has a home zone, the geographic area the school must serve. Live inside the home zone and your child is entitled to enrol. Live outside it and you enter a ballot, a random draw for a small number of out-of-zone places.

The "Double Grammar Zone" has no official standing. It's the informal name for the patch where the Auckland Grammar zone and the Epsom Girls' Grammar zone overlap. A home inside that overlap carries an in-zone right to both schools, which is what families are really paying for. In-zone is a right. Out-of-zone is a hope.

What suburbs does the Double Grammar Zone cover?

Based on the two schools' published zones as at mid-2026, the overlap covers all of Epsom, plus parts of Mount Eden, Remuera, Greenlane, Parnell and Newmarket.

The word carrying the weight in that sentence is "parts". Outside Epsom's core the coverage follows specific street boundaries, and in places it splits individual streets. Two houses a few doors apart can sit on opposite sides of the line. This is why assuming "we're in Remuera, so we're zoned" is a costly mistake.

Where can I find the official Auckland Grammar and Epsom Girls’ Grammar zone maps?

Auckland Grammar publishes a zone map and a street-by-street list of in-zone addresses on its enrolment pages, and dates the list (the current one states it's correct as at February 2026). The boundary is described by named streets, not suburbs, which is exactly why a glance at a map isn't enough.

Epsom Girls' Grammar publishes its own zone map, enrolment scheme and Home Zone Address List. Its zone covers parts of Epsom, Remuera, Parnell and Mount Eden. Worth knowing: as at mid-2026 its out-of-zone applications for the year had already closed, a reminder that timing matters as well as address.

How do I check if a specific address is in the Double Grammar Zone?

Start online, and escalate only as far as your own certainty requires. This is how we work it out ourselves.

Start with the official sources. Check the full street address, not the street name, against both schools' published zone information. Zones are described street by street and they split streets, so the address is the unit that matters. Check both schools, because a home can sit inside one zone and outside the other, and "double" needs both to say yes. Note the date each school states its information is correct as at.

Still unsure, and you need an answer today? Phone the enrolment office. Offers can close in days, and an email may take longer than you have. A phone call reaches someone who answers this question every week.

Still unsure, and you can wait a day or two? Email instead. You get the same answer in writing, which is the point. Keep it. It is what you want if the question comes up again between going unconditional, the moment your contract becomes binding, and settlement, the day you pay and take ownership.

Do not rely on a zone map published by anyone else, and do not rely on the agent. Not because anyone is lying. It is that if the boundary moved last year, they do not pay the price for the mistake, you do. The schools set their own boundaries. That makes the school the only source whose answer means anything, and the only one still correct after every other map goes out of date.

What happens if the zone boundary changes after I buy?

Nobody can promise a boundary holds forever. Schools review their enrolment zones, and the lines do move.

What you are buying is an entitlement under the boundary as it stands on the day you buy, confirmed in writing by the school. That is the strongest position available to any buyer, and it is worth having precisely because it is not a guarantee about the future. It is a record of what was true when you committed, from the only party entitled to say so.

This is also the practical reason to re-confirm before settlement if months have passed. A change is unlikely. But checking costs one phone call, and being wrong costs you the reason you bought the house.

Does being in the Double Grammar Zone add value to a property?

In-zone homes in this part of Auckland sell for a premium, meaning buyers pay more for them than for similar homes just outside the boundary. It's commonly discussed at around 10 to 20 per cent, though it varies by street and by cycle, so treat any single number as indicative.

Be clear about what you're buying: an entitlement under the boundary as it stands today. Nobody can promise the boundary holds forever. For families the entitlement is usually the whole point. For downsizers and buyers with no school-age children, the zone still helps when you come to sell, because families are looking for in-zone homes every year. Either way the premium only exists if the address actually qualifies, which is why the check above isn't optional.

We have built in this part of Auckland, and school zoning came up in nearly every buyer conversation on those projects. Our completed Logan Apartments sits at Greenwoods Corner in Epsom, inside the zone. For the wider picture of the suburb itself, see living in Epsom. One of those homes, a single-level penthouse at the Logan, is on the market now, in-zone for both schools.

This is general guidance only. Confirm any address directly with both schools before you commit. If you'd like to be the first to hear about our next development, register your interest.
