We publish monthly Fund performance data dating back to when it first started investing in 2003.

The above graph shows the growth in the size of the Fund since investing began in 2003. It illustrates the impact of the Global Financial Crisis in 2008/09 and the COVID-19 crisis in 2019/20, and the subsequent recovery in the value of the Fund. Between 2009 and 2017 Government contributions to the Fund were suspended. As at 30 June 2022, the Government had contributed a total of NZ$22.38 billion to the Fund.

 

The table below sets out the Fund's returns since inception (September 2003) on a monthly basis. Click on the relevant year to see month-by-month returns.

We disclose:

  • Total Fund Return (after costs, before NZ tax)
  • Treasury Bill Return (proxy for the cost of debt) - the rolling yield on 90 day Treasury Bills
  • Net return (returns over and above the Treasury Bill return)
  • Reference Portfolio Return (passive benchmark)
  • Value added by Guardians (compared to Reference Portfolio)
  • Fund size. This is shown in NZ dollars and inclusive of net investment income, but excluding provisions for NZ tax.

Please note that:

  • these figures are unaudited. For audited figures please refer to our Annual Reports
  • all Fund returns are quoted after fees and before NZ tax. Returns are measured on a 'time weighted' basis (monthly compounding). We measure on a 'time weighted' basis because we do not have control over the flow of cash in and out of the Fund
  • from 1 July 2007, the Fund has applied New Zealand International Financial Reporting Standards (NZ IFRS), under which listed securities are valued based on the end of day bid price on the relevant exchange. In line with common market practice, performance continues to be reported based on last sale price;
  • not all assets are valued on a monthly basis;
  • prior to July 2010, the column showing the Reference Portfolio Return refers to a previous performance benchmark, which used a Strategic Asset Allocation methodology.
