The 2022 RRIP investigated decumulation – the process by which savings and investments are used to pay for retirement – “drawing down savings.”

Research found that more education is required to support New Zealanders using their savings in retirement, including guidance and “rules of thumb” for spending their KiwiSaver.

A paper commissioned for the 2019 RRIP provided an assessment of decumulation of retirement savings and other assets. Download the paper.

Another report from the 2019 RRIP also considered decumulation, and considered decumulation models available in a number of OECD countries. Download the report.

The 2016 RRIP looked at decumulation from a number of perspectives, including surveys, reports and interviews with the public.
