New interactive tool:

Every year, the New Zealand Treasury publishes data on previous national budgets in Excel files containing over 7,000 entries. The sheer amount of data makes it arduous 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 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, using the download button.
