Figure 10: Sectoral contributions to the current account (March year, share of GDP)  Source: Statistics New Zealand (Income and Expenditure account), RBNZ estimates.
Note: (1) Income and Expenditure data by sector is available only to March 2016. Within this, business sector data is only available to March 2015, so the March 2016 contribution is estimated as a residual; (2) consistent gross saving and investment data for non-government sectors are only available from 1999, so their contribution is captured in the ‘private sector’ data prior to this.
