For the purposes of making commenting on the 2015 Budget a little easier, here’s some information about where government gets its money from, and where it spends it. This is taken from the 2014 Budget figures.
Most of government’s money comes from tax. This is the breakdown of government revenue from the 2014 Budget.
Government spends most of its income on welfare, health and education. The single biggest item of government expenditure is New Zealand superannuation.
Details on government revenue and government expenditure were sourced from the 2014 Budget page on the NZ Treasury website. The revenue and expenditure figures above exclude income and expenditure by SOEs.
