What is open data?

Open data is data anyone can use and share. It has an open licence, is openly accessible and is both human-readable and machine-readable.

You’re probably already using open data every day – for example:

  • geospatial information (getting from A to B)
  • weather data (deciding how to dress for the day)
  • census data (making business decisions).

Open data drives innovation. It helps to build new business and encourages more strategic investment – creating new jobs, new industries and stronger economies. It can also lead to positive social and cultural outcomes, and can increase transparency and democratic participation.

Learn the basics - the open data toolkit

The open data toolkit was designed to help governments and open data enthusiasts understand the basic concepts of open data, how to plan and implement an open government data programme and some tricks on how to approach a dataset. It resulted from a collaboration between Code for Aotearoa and Land Information New Zealand.

The toolkit provides a basic step-by-step approach to help government agencies release more open data in a simplified manner. Covering topics such as:

  • What is open data?
  • Why open data?
  • Examples of open data use
  • The groundwork required to release open data
  • The toolkit itself (with each stage of the release process).

If you want comprehesive guidance to help you release open government data, then refer to the open data release checklist.

Case studies

As the open government data and information programme helped government organisations, we also worked closely with non-government groups using that data for public good. In our showcase, we have collected some of the inspiring uses of government data for you to read.
