The New Zealand Superannuation Fund, the sovereign wealth fund part funding New Zealand’s old-age pension from 2029/2030 onwards, has been a bit of a wild ride. Sometimes the earnings of the Fund were well below and sometimes earning well above the long-term bond rate.

Since its inception, the Fund earned an average annual return of 9.78%, which was 5.06% above the long-term bond rate, and 1.03% above its reference portfolio.

No information was given in the annual report of the New Zealand Superannuation Fund on the marginal dead weight cost of the taxes raised to fund the New Zealand Superannuation Fund to see whether there is any net benefit to taxpayers from its establishment and continued operation.

The New Zealand Government has contributed $14.88 billion to the fund from prior its inception in 2001 to the suspension of contributions in 2009 by the incoming National Party Government.

Over the nine years in which contributions were made, the company tax rate of 28% could have easily been up to 10 percentage points lower.
The New Zealand Treasury estimates that a one percentage point cut in the company tax costs about $220 million in forgone revenue if there are no other changes to the tax system. These are static estimates that do not include any feedback from greater investment and higher growth.
The New Zealand Superannuation Fund must beat the market every single year to make up for the deadweight cost of its funding, a premium for the investment risk added to the Crown’s portfolio and the cost to New Zealand’s growth rate of higher than otherwise taxes on income, entrepreneurship and investment.

Figure 1 shows a divergence from a common starting point in 1974 effective retirement ages. The French in particular were the first to put their feet up and start retiring by the age of 60 by the early 1990. There was also a sharp increase in the average effective retirement age for men in the UK over a short decade. After that, British retirement ages for men started to climb again in the late 1990s. Figure 1 also shows that the gentle taper in the effective retirement age for American men stopped at the 1980s and started to climb again in the 2000s. The German data is too short to be of much use because of German unification. France only recently stopped seeing its effective retirement age fall and it is slightly increased recently – see figure 1

Figure 2 shows similar results for British and American women as for men in the same country shown in figure 1 . That is, falling effective retirement ages for both British and American women in the 1970s and 1980s followed by a slow climb again towards the end of 1990s. French effective retirement ages for women followed the same pattern as for French retirement ages for men – a long fall to below the age of 60 with a slight increase recently. The German retirement data suggest that effective retirement ages for German women is increasing.

Figures 1 and 2 shows a sharp increase in the average effective retirement age for men and women in both Australia and New Zealand between 1970 and 1990. After that, retirement ages for men in both countries stabilised for about a decade. effective retirement age than Australia.

Interestingly, in the 1970s and 1980s, New Zealand had an old-age pension scheme, known as New Zealand Superannuation, whose eligibility age was lowered from 65 to 60 in one shot in 1975. This old-age pension in New Zealand had no income test or assets test, but there was for a time a small surcharge on any income of pensioners. Nonetheless, New Zealand had a higher effective retirement age than in Australia where the old-age pension eligibility age is 65 with strict income and assets tests.

Figure 1 and figure 2 also shows that the sharp increase in effective retirement ages in New Zealand for both men and women after the eligibility age for New Zealand’s old-age pension was increased from 60 to 65 over 10 years.
Figures 1 and 2 also show the gradual increase in effective retirement ages for Australian men and women from the end of the 1990s.
