The Treasury's Role
The Treasury is responsible for forecasting how much tax revenue the government can expect to earn. Twice a year the Treasury publishes Economic and Fiscal Updates which forecast revenue for the following five years.
The Financial Statements of the Government of New Zealand report on revenue that the government has received.
Inland Revenue also forecasts how much the government is likely to receive in revenue in future years. The Budget Economic and Fiscal Update 2018 has tables showing both departments' forecast figures. The Treasury's forecasts are the Crown's official forecasts.
The Treasury provides tax policy advice jointly with the Inland Revenue.
The three largest areas of total Crown expenditure for the 2016/17 financial year were:
- Social security and welfare: $30.6 billion
- Health: $15.6 billion
- Education: $14.1 billion
These figures are taken from the Analysis of Expenses by Functional Classification Total Crown in the Financial Statements of the Government of New Zealand for the Year Ended 30 June 2017. See the Analysis of Expenses for information on other areas of government expenditure - such as defence and transport and communications - and for a comparison with the 2015/16 figures.
