New Zealand Superannuation Fund Contribution Rate Model
Page updated 25 Oct 2011
Treasury model used to calculate the government's capital contribution to the New Zealand Superannuation (NZS) Fund.
This model in MS Excel workbook format calculates the contribution rate for pre-funding New Zealand Superannuation (NZS). The model was updated at the time of the release of the Pre-election Economic and Fiscal Update 2011 (PREFU).
Since the last release with the Budget Economic and Fiscal Update 2011 (BEFU) the model's data inputs have been updated. Specifically, the model uses the latest five-year forecasts of the Fund's earnings and tax payments and longer-term projections of nominal GDP and total net (after-tax) NZS expenditure.
This version of the model includes no capital contributions between the years 2010/11 and 2016/17. Government policy is to review the length of this non-contribution period as economic and fiscal conditions change. Any changes will be reflected at each update of the NZS Fund projections.
