Introducing eolas: every official New Zealand dataset, one API

New Zealand publishes an extraordinary amount of official data. The catch is where: Stats NZ on one portal, RBNZ on another, LINZ on a third, every regional council on its own ArcGIS hub, the Treasury in a spreadsheet, GeoNet on a feed. Different formats, different update cadences, and — the part almost nobody checks until it matters — different licences.

eolas is that whole landscape behind one API.

Today there are 1,400+ datasets from 34 sources live: the core economic series (Stats NZ, RBNZ, Treasury, MBIE), the spatial base (LINZ, the full set of statistical boundaries), transport and safety (Waka Kotahi), health and social data (ACC, PHARMAC, MSD, Education Counts), every regional council's geospatial layers, and more landing every week.

One query

from eolas_data import Client
client = Client("your_api_key")

cpi   = client.get("nz_cpi")  # OECD — annual CPI % change
rates = client.get("rbnz_b2_wholesale_rates_monthly")

Two official sources, two lines, two tidy data frames with dates already parsed and ready to join. There's an R client (eolas) and a CLI too — same data, same shape.

The part we care about most

Every table carries its licence as metadata. We read the copyright statement on every source, recorded the answer, and only serve data we can stand behind. When you pull a New Zealand dataset through eolas, the answer to "can I actually use this in a commercial product?" comes with it — because for most of this data the answer is yes (CC-BY 4.0), and knowing which is most of the work. (We wrote up the full New Zealand open-data licence landscape if you want the map.)

Who it's for

Analysts, data teams, and businesses who need New Zealand official data and would rather not maintain 34 brittle scrapers. If you've ever written a one-off script to pull a Stats NZ table, then written it again three months later when the URL changed, that's the job eolas does once, for everyone, and keeps doing.

There's a free tier — enough to build something real and decide if it's for you. Paid tiers lift the row caps and add the Snowflake zero-copy share for teams that want the data in their warehouse rather than through an API.
