Abstract
The objective of this paper is to analyse the extent to which membership of KiwiSaver has been associated with greater accumulations of net wealth.
The paper utilises two linked sources of data which cover the period 2002 to 2010: Statistics New Zealand’s Survey of Family, Income and Employment and Inland Revenue Department administrative data on KiwiSaver membership.
Two approaches are employed: difference-in-differences (where the outcomes of interest are changes in net wealth) and various panel regression techniques.
Results appear consistent with earlier evaluations of KiwiSaver. Neither approach suggests KiwiSaver membership has been associated with any positive effect on net wealth accumulation.
