Open data in New Zealand

Government initiatives

Within the New Zealand government, the move towards open data has been spearheaded by the Open Government and Data Programme (Open Data NZ), (Department of Internal Affairs) and Statistics New Zealand. These groups are currently working on commitments 3 and 4 of the Open Government Partnership New Zealand's National Action Plan 2016–18: improving open data access and principles, and tracking progress and outcomes of government open data release.

Open Government Data Programme (Open Data NZ)

Stats NZ hosts New Zealand’s cross-government Open Government Data Programme (Open Data NZ). Open Data NZ takes a collaborative approach to making government-held data and information widely available for agencies, communities and businesses to reuse. is a directory of publicly available New Zealand government datasets, hosted by the Department of Internal Affairs (DIA). The site focuses on machine-readable (well-structured and open) datasets, but recognises that 'grey' data (for example, web pages) can still be of use to developers and others. Open Data NZ works with agencies to release their data as open, and DIA works with agencies to improve data formatting.

Statistics New Zealand

Statistics New Zealand gathers data on many topics – including income, housing, the environment, the economy, education and social well-being – which is released as open data.

Open licensing

The New Zealand Government Open Access and Licensing framework (NZGOAL) is all-of-government guidance for agencies to follow when releasing copyright works and non-copyright/public domain material for reuse by others. It aims to standardise the licensing of government information and data using Creative Commons licences, and provides public-domain statements for material no longer under copyright or where copyright has lapsed over time. Use this guidance when you intend to release open data.

Open data policy

Declaration on Open and Transparent Government

The Declaration on Open and Transparent Government was made by Cabinet in 2011. It sets out a government-wide approach to increasing the openness and transparency of the New Zealand government, by actively releasing high-value public data it collects and holds on behalf of taxpayers.

New Zealand Data and Information Management Principles

The New Zealand Data and Information Management Principles (NZDIMP) are a set of seven principles under which the New Zealand government releases its open data.

The principles state that data should be:

  • open
  • protected
  • readily available
  • trusted and authoritative
  • well-managed
  • reasonably priced (preferably free)
  • reusable.

Unless there are identifiable reasons for its release, personal and classified data remains protected. Government data and information should also be trusted and authoritative.
