Every year, the New Zealand Treasury publishes data on the last six national budgets, in two Excel files containing over 7,000 entries. The sheer amount of data makes it very difficult to assess the composition of revenues and expenditures and how they changed over time. This interactive tool allows you to plot New Zealand's budgets as you please: by year, the type of spending or revenue, the portfolio, the department in charge, and more. You can download the data underlying each figure you build, in an Excel format using the download button below.
