The Labour-led Government is spending $1000 more per capita than the previous National Government.
Analysis of yesterday's Budget shows total Crown spending will rise to $16,870 per person by 2021, compared to National's planned spending of $15,917 in its 2017 Budget.
The analysis was by Victoria University's Institute for Governance and Policy Studies and the New Zealand Institute of Economic Research, and took into account population increases and inflation.
The biggest portion of the increase is in welfare, in which the Government will spend $277 more per head.
It is also spending $166 more on health and $145 more in education per person.
