Stats Nz MCP server

@pipeworx/stats-nz

New Zealand official statistics (Aotearoa Data Explorer) — search Stats NZ's 911 published datasets by keyword and pull their observations, covering the 2013/2018/2023 censuses, LEED earnings, business demography, population estimates and projections, household expenditure, corrections and justice.

Part of Pipeworx — an MCP gateway connecting AI agents to 1679+ live data sources.

Tools

911 datasets; returns dataset id, full title, description, agency, version.

• statsnzdatasets({ query, limit, offset }) — keyless**. Keyword-search all

• statsnzobservations({ dataset, key, agency, version, startPeriod, endPeriod, lastNObservations, apiKey }) — period/value pairs with their dimension labels.
• statsnzresources({ dataset, agency, version, includeCodes, maxCodesPerList, apiKey }) — dimensions in key order, time dimension, measure, and the code lists that turn a key like 1.2.Q into something readable.

Auth

Platform key PLATFORMSTATSNZKEY (in the encrypted keystore since 2026-09-18) with BYO override via ?_apiKey=; sent upstream as an Ocp-Apim-Subscription-Key header. Callers need no key of their own. Free subscription at — sign up, then subscribe to the Aotearoa Data Explorer API product.

statsnz_datasets additionally works with no key at all.
