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

By James Guilford · Development Manager, Heartland Developments

The DGZ is the overlap of the Auckland Grammar and Epsom Girls' Grammar enrolment zones, and it does more work in an Auckland property search than any number of bedrooms. Here's what it covers and the address check most buyers get wrong.

For a lot of Auckland families, "Double Grammar Zone" does more work in a property search than any number of bedrooms. It means the area where the enrolment zones of Auckland Grammar School (boys) and Epsom Girls' Grammar School (girls) overlap. Live inside both zones and your children have a guaranteed in-zone entitlement to both schools.

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

Before anything else, one caveat that the rest of this page exists to serve: the schools are the only authority on their own boundaries, and boundaries change. Everything below is general guidance. The exact address you're buying gets confirmed with the schools, in writing, or you don't rely on it. That's the whole game.

What the zone actually is

Over-subscribed state schools in New Zealand run an enrolment scheme with a defined home zone. Inside the zone, your child is entitled to enrol. Outside it, you're in a ballot for a limited number of out-of-zone places.

The "Double Grammar Zone" isn't an official designation. 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.

Where it covers

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 "we're in Remuera, so we're zoned" is one of the more expensive assumptions in Auckland property.

The two schools

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 to check an address properly

This is the part that protects you, and it takes less than an hour.

Check the exact address against both schools' official zone tools, not one. A home can be in one grammar zone and not the other; "double" needs both. Note the "correct as at" date on each list, because boundaries are reviewed and do move. Then contact each school's enrolment office and get written confirmation for the specific property, by email so it's on record. A phone "yes" isn't enough for a purchase this size. And if months pass between going unconditional and settling, a fresh confirmation costs nothing.

Don't rely on a third-party zone map, and don't rely on the agent. Not because anyone's lying, but because nobody else carries the consequence if the line moved last year.

What the premium buys

In-zone homes in this part of Auckland carry a recognised premium over comparable homes outside the line. 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, not a guarantee the boundary holds forever. For families the entitlement is usually the whole point. For downsizers and buyers without school-age kids, the zone still works for you at resale, because the demand it creates never takes a year off. Either way the premium only exists if the address actually qualifies, which is why the check above isn't optional.

We build in this part of Auckland, and school zoning comes up in nearly every buyer conversation we have. Our completed Logan Apartments sits at Greenwoods Corner in Epsom; for the wider picture of the suburb itself, see living in Epsom.

This is general guidance, not an enrolment ruling. Confirm any address directly with both schools before you commit. If you'd like to hear when Heartland opens registrations on a new release in the inner south, register your interest.
