Data sources

Freshness

The Latest data column is for the date of the newest snapshot we have published from each source. A source is flagged as stale when that date is older than one and a half times its update cadence. This page does not show those dates yet; each metric's own date is shown wherever the metric appears.

Sources

Blocked sources

Registered, but not fetched until the stated condition is met.

• Market Rent API v2 (Ministry of Business, Innovation and Employment (MBIE) — Tenancy Services): Requires a signed MBIE API Access Agreement and MBIE's manual approval of the subscription (approvalRequired=true for sandbox and production); blocked pending both.
• Flood hazard for NZ flood plains (1% AEP rainfall; current, +1/+2/+3 °C) (Earth Sciences New Zealand (formerly NIWA)): The free tier is CC BY-NC 4.0 ("NonCommercial — You may not use the material for commercial purposes"), and suburbmap's embeds, API licensing, reports and any advertising are commercial use. Commercial Restricted (NZD 500 per by-region item) is limited to "a one-off project" and forbids outputs that "reproduce significant tranches or the full set of the Data". Needs a licence from ESNZ (data-enquiries@earthsciences.nz).
• Extreme coastal flood maps (1% AEP + sea-level rise to 2 m) (Earth Sciences New Zealand (formerly NIWA)): Conflicting licences: the publisher's FeatureServer item is "Creative Commons Attribution-No derivatives 4.0 International License (CC BY-ND 4.0)" (SA2 exposure percentages, clipping or re-tiling may be Adapted Material), while the DataHub national FGDB of the same data is under ESNZ's Non-commercial Use licence, which forbids making Data or Outputs available to third parties (except Reports) and counts "displaying either on a website that directly generates revenue from advertising or is pay-to-view" as commercialisation. Needs ESNZ's written clarification or permission.
• GWRC flood hazard layers (Greater Wellington Regional Council): The item licence is GWRC's website terms: "you are not permitted to copy or republish any substantial amount of the information from this website without the prior written consent of The Council", which overrides the CC BY 4.0 default on gw.govt.nz/your-council/legal. Public tiles and SA2 exposure need GWRC's written consent (gissupport@gw.govt.nz) or relicensing.
• WCC District Plan flood hazard overlays (Wellington City Council): Purpose-limited custom licence: "This feature layer has been created for the District Plan of Wellington City Council. If you require something beyond this purpose, please contact the WCC District Planning team". Commercial re-display and derived statistics need WCC's confirmation, and the underlying Wellington Water depth bands need WWL's consent before third-party distribution.
• Hutt City flood hazard layers (Hutt City Council): HCC Open Data terms: "you are not permitted to copy or republish any substantial amount of the information from this website without the prior written consent of Hutt City Council". Consent from HCC is needed before publishing tiles or statistics; Wellington Water's 2024 depth bands require acknowledgement but grant no explicit licence.
• PCC flood hazard layers (ponding, overland flow, stream corridor) (Porirua City Council): No licence stated: licenseInfo is empty on every PCC flood item, the Hub reports licence type 'none' and CKAN says "Other licensing (check with source agency)". Needs written confirmation from PCC (and possibly Wellington Water, named in the items' credits) before publishing.
• Wairarapa Combined District Plan Decision Flood Hazard Areas (Wairarapa councils (Masterton, Carterton and South Wairarapa District Councils)): Licensed "CC BY-ND 4.0" (NoDerivatives): verbatim display may be fine, but derived SA2 exposure percentages and reprojected, simplified or tiled derivatives may breach ND. Needs permission from MDC, CDC and SWDC or GWRC, or a licence opinion.
• Tsunami evacuation zones (Wellington region) (Greater Wellington Regional Council / Wellington Region Emergency Management Office): Conflicting licences on four GWRC items for Emergencies_P/MapServer/23. The hub and data.govt.nz item is "Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International" (NonCommercial conflicts with embeds, API licensing and reports; NoDerivatives with tsunami_zone_share); others say CC BY 4.0, GWRC website terms (no substantial copying without written consent) or "can be passed on to a third party but copyright needs to be acknowledged". Needs written confirmation and commercial permission from GWRC/WREMO.
• NZ Active Faults Database (1:250k, AF250) (GNS Science / Earth Sciences New Zealand): Non-commercial only: "The Active Fault Data presented here cannot be used for commercial purposes including, but not limited to, reselling and/or providing technical services based on the Data" (the AF site terms add "The NZAFD must not be used for any form of commercial use"; the DataHub copy is under ESNZ's Non-commercial Use licence). suburbmap's embeds, API licensing and reports are commercial; needs ESNZ/GNS permission.
• Flood Plains, Flood Prone Areas, Overland Flow Paths, Coastal Inundation (Auckland Council): The items grant CC BY 4.0 and then state "You are not permitted to copy or republish any substantial amount of the information from this website without the prior written consent of Auckland Council"; Flood Plains carries no licence grant, and the council site terms say "You are not permitted to copy and sell or exploit for commercial purposes, any material on this website". Needs Auckland Council's written consent (Healthy Waters / open data team) before publishing (SPEC §16.10).
• Earthquake-prone buildings register (Ministry of Business, Innovation and Employment (MBIE)): Bulk CSV only by request to MBIE; do not scrape (SPEC §5, §16.7).
