Wellington, Wellington Region publishes open datasets and APIs to support reuse by developers, researchers and businesses. This guide explains where to find official Wellington datasets, how licences apply, practical steps for API access, and how council rules affect reuse. It focuses on Wellington City Council sources and national licence guidance to help you request, cite and comply with dataset terms when working with council data.

Where to find official datasets

The Wellington City Council maintains a maps and open data catalogue and publishes many datasets through its portals and national catalogues. Look for dataset metadata, download formats and API endpoints on the council’s maps and data pages and on New Zealand’s central data catalogue.

  • Common datasets: transport routes, parking bays, property and rates, public amenities, tree and asset inventories.
  • Access methods: direct downloads (CSV, GeoJSON), REST API endpoints, and WFS/WMS for spatial layers.
  • Metadata: each dataset page should state a licence, update frequency and contact point for corrections.
Always check the dataset metadata page for licence and attribution details before reuse.

Penalties & Enforcement

Open data publication and licence enforcement for Wellington datasets are managed through council publishing policies and terms; specific monetary fines or penalty figures for licence breaches are not stated on the council open data pages and so are not specified on the cited page.[1]

  • Fines: not specified on the cited page.
  • Escalation: the council may first seek compliance or correction; formal enforcement steps are not detailed on the open data page.
  • Non-monetary sanctions: potential remedies include takedown requests, correction orders or pursuit of breach through civil remedies; specifics are not published on the dataset pages.
  • Enforcer: Wellington City Council departments administer data publication and may handle complaints through their listed contacts.
  • Appeals/review: routes and time limits for review of enforcement actions are not specified on the cited page.
If you receive a compliance notice, contact the council promptly to discuss remedies.

Applications & Forms

The council does not publish a separate generic application form for open data access; most datasets are downloadable or accessible via API endpoints and corrections or special requests are usually handled by contacting the dataset owner or council service contact listed on the dataset page.[1]

Licences and attribution

Licence terms for Wellington datasets vary by dataset. Licence guidance for New Zealand public sector data is published centrally and dataset pages should show the specific licence to apply to each file or API resource.[2]

  • Licence on dataset page: follow the licence text and attribution requirements shown on each dataset metadata record.
  • Variations: some datasets may use Creative Commons or Crown copyright terms; check the dataset record before reuse.
  • Attribution: include the dataset title, publisher (Wellington City Council) and licence when reusing data as required by the licence text.
Licence details are provided per dataset and may differ between records.

How to report data errors or request additional access

  • Find the dataset contact on the dataset metadata page and email the listed officer with details of the error and a suggested correction.
  • For high-volume API access, notify the data owner to request API keys or rate limit increases if available.
  • If you believe a licence has been breached, collect evidence and contact the council to seek resolution.
Keep screenshots and request timestamps when reporting data errors to speed resolution.
