Every figure on this page is measured from the source registers named beside it, for the whole suburb — not for any one address. Site-specific answers need the parcel itself. Which parcels count as Brookby: LINZ address attribution — a parcel belongs to the suburb if it contains at least one address point whose suburb_locality is this suburb. No radius, no drawn boundary: the database holds no suburb/locality polygon layer. The median site is the middle of all 131 of them, commercial and reserve included. Data as at .
Zoning
What Brookby is zoned
3 zones cover Brookby; Rural: Mixed Rural holds 92.3% of its parcels. The zone decides the height, coverage and yard rules below — and it is the first thing that changes what a site is worth building on.
- Rural: Mixed Rural 92.3%
- Rural: Countryside Living 6.9%
- Quarry 0.8%
| Zone | Parcels | Share of parcels | Share of land | Median site |
|---|---|---|---|---|
| Rural: Mixed Rural | 120 | 92.3% | 94.7% | 41,947 m² |
| Rural: Countryside Living | 9 | 6.9% | 5.0% | 3,815 m² |
| Quarry | 1 | 0.8% | 0.4% | 59,316 m² |
Source: Auckland Unitary Plan (Operative in Part). Each address-bearing parcel is assigned the zone covering the largest share of it (same rule as the site report). Shares are given both by parcel count and by land area. standards[].notes is an internal audit trail, not page copy — do not display it; standards[].activity_over_note is the opposite, it is written for readers and explains the permitted dwelling count. Both weightings are printed because they disagree on purpose: share of parcels is how many owners a rule applies to, share of land is how much ground it covers — one large reserve outweighs a whole street on the second and barely registers on the first. The headline figures on this page use share of parcels.
Rental market
What it rents for
Brookby spans 4 statistical areas and each has its own median. There is no single "Brookby median" to quote — medians cannot be averaged together — so the headline below names the area it belongs to. 2 of those areas have enough bonds lodged to publish one.
This counts every tenancy in that area at once — studios, one-bedroom flats and family houses in the same median. It is not the rent of a three-bedroom house.
| Statistical area | Share of Brookby | Median /wk | Bonds |
|---|---|---|---|
| Turanga | 90.1% | $835 | 45 |
| Clevedon | 8.4% | $600 | 30 |
Source: MBIE / Tenancy Services bond lodgements, 12-month rolling window ending June 2026. MBIE tenancy bond medians by SA2 (2018 boundaries) over the latest 12-month rolling window ending June 2026 — the window MBIE itself computes the median on, not four quarterly medians averaged together (medians do not average). Medians are reported per SA2 and never averaged across SA2s — a suburb usually spans several SA2s, and averaging medians is not a median of anything. The headline SA2 is the one holding the most of the suburb's parcels. Bedroom counts resting on fewer than 30 bonds lodged in the window are omitted rather than shown as zero. An indication of the rental bond market for this area, based on bonds lodged with Tenancy Services — not a market rent for any individual property. Every figure here stands on at least 30 bonds — counted as bonds lodged during the window (the sample the median is computed on), not the active stock. That is a small sample, and it is the honest one: the median is computed on exactly those bonds. Thinner cells are dropped at source rather than shown as a zero, so nothing on this page sits below that floor. No bedroom size in Brookby cleared it over this window, so this page carries no by-bedroom table — the figure above, across all bedroom counts, is the only median publishable here. One-bedroom medians are withheld for this window: Omitted for this window: MBIE's own bedroom coding is off in at least one quarter it covers — the 1-bedroom bucket holds up to 67.2% of newly lodged bonds against a long-run 18-23% share, i.e. bonds with an unrecorded bedroom count have been folded into it (MBIE's own NA bucket collapsed from 1,386 cells to 26 when this first showed). A rolling window dilutes a bad quarter, so the test is applied per quarter, not to the window as a whole. Restored automatically once every quarter in the window is back below 30%.
Development contributions
What the council charges per new dwelling
A one-off charge levied at consent stage, per household equivalent unit (HUE). It is the largest council cost most people never see coming — and it is set by where the site sits, not by what you build.
| Activity | Funding area | Level | Per HUE |
|---|---|---|---|
| Reserve acquisition | Rural South East | Local | $349 |
| Reserve development | Rural South East | Local | $480 |
| Stormwater | Wairoa | Local | $156 |
| Transport | Rural South | Local | $6 |
| Community infrastructure | Auckland wide | Regional | $646 |
| Reserve acquisition | Auckland wide | Regional | $441 |
| Reserve development | Auckland wide | Regional | $25 |

Auckland Council development contributions per additional dwelling (1 HUE), resolved per parcel from the 2025 policy funding areas. Parcels in the suburb are grouped by their funding-area combination; the headline is the combination covering the most parcels. breakdown itemises that headline combination by activity and funding area — the rates add up to the headline figure, they are not shares of it. Development contributions are one-off per-HUE charges levied by Auckland Council at consent stage; shown here at 2026/27 invoice-year rates under the 2025 policy funding areas, one dwelling = 1 HUE (reductions for small/multi-unit dwellings per Schedule 2). The council's invoice is definitive. Existing dwellings on the site are credited — a two-into-three development pays for the net additional units, not all three. Rates rise each policy year.
Schools
Enrolment zones covering Brookby
Percentages are the share of Brookby parcels that fall inside each school's enrolment zone. A zone boundary can run down the middle of a street, so treat this as the suburb's shape — the address decides.

EQI = Ministry of Education Equity Index (lower = fewer socio-economic barriers). Deciles were discontinued in 2023 and are deliberately not shown or back-derived. vintage is the date the school roll and zone data itself is current to — not the date this page was generated. EQI is the Ministry's Equity Index — a lower number means students face fewer socio-economic barriers. It replaced deciles in 2023 and we do not back-calculate the old ones. Zones change; schools with no zone enrol from anywhere and do not appear here. This is coverage, not a ranking — we publish no school quality score on this page.
Flood exposure
How much of Brookby is mapped as flood-affected
- Floodplain 77.9%
- Modelled 1% AEP inundation extent (rivers and overland flow).
- Flood-prone 46.6%
- Topographic depressions with no outlet, where water ponds.
The two layers overlap, so these do not add up to the figure on the left — a parcel can sit in both.
Share of address-bearing parcels in the suburb whose boundary intersects each mapped Auckland Council flood layer, and the share touching at least one of them. The two layers overlap, so the shares do not add up — read any_layer as 'touches at least one'. Intersecting does not mean the whole site floods: depth and extent vary within a parcel.
Source: Auckland Council flood plains and flood-prone areas, both layers. "Touches" means any part of the parcel meets a mapped layer — most affected sites are affected at one corner, not throughout, and the maps model overland flow rather than record past floods. This is not a flood assessment and it is not the same thing as insurability.
