Making Good Choices for the Long Run: the economic benefits of KiwiSaver in 2100

As New Zealand faces the challenges of an ageing population and widening inequality, it is useful to ask: what is the long-run economic role of KiwiSaver, is it an inclusive institution, and how can it be strengthened for future generations? This article explores the economic benefits of KiwiSaver beyond individual retirement outcomes in the future. It examines whether KiwiSaver contributes to national savings, reduces long-term fiscal pressures, and supports intergenerational inequality by promoting early asset-building. Considering case studies from Singapore, Australia and the Netherlands, the article highlights how starting earlier, contributing more and investing better can build economic resilience, increase capital accumulation, and reduce social polarisation by supporting intergenerational equity. The findings of this research and focus on the need for long-term stewardship allows us to think deeply about how today’s contributions to KiwiSaver can shape a better future for the younger generations in the year 2100.
