Income protection in the New Zealand tax-transfer system

Abstract

This research note investigates income-replacement rates provided by the New Zealand welfare system when an individual loses their employment. We utilise New Zealand Treasury’s microsimulation model, based on tax and transfer rules from April 2018 to March 2019, for a variety of household scenarios. Results indicate that replacement rates are higher (above 50 percent) for those with children and for those earning low and median wage rates. These findings are highly relevant to policymakers, as they provide indicators of the adequacy of the welfare system and can inform design aspects of a potential unemployment insurance scheme.
