The New Zealand Superannuation Fund finished the June year worth $94.4 billion, $9.3 billion more than a year earlier, after a second strong run on global sharemarkets. The Guardians of New Zealand Superannuation, the Crown entity that manages the money, released the provisional result on Wednesday, reporting a return of 14.17 percent after costs and before New Zealand tax for the 12 months to 30 June 2026.
The more striking number sits underneath the headline figure. The Guardians’ own published performance data shows the Fund paid $2.52 billion in New Zealand income tax over the year while the Government contributed nothing to it. For the first time in the Fund’s working life, the flow of money between the Crown and its own investment vehicle ran entirely one way, and it ran towards the Crown.
Chief executive Jo Townsend said the Fund was already making a positive contribution to the Government’s books. “Over the past year, we were again New Zealand’s largest taxpayer. Treasury forecasts that for the next five years our tax payments will exceed the Government’s required capital contribution by more than $1 billion a year, with the difference expected to top $2 billion in 10 years’ time,” she said.
Townsend called the result a satisfying one and said it followed strong performances in the previous two years. The Fund’s 14.17 percent return was well clear of the 2.71 percent yield on 90-day Treasury bills over the same period, the benchmark the Guardians use to represent what the Government would have saved by using the money to pay down debt instead. On that measure the Fund earned $9.53 billion more than the alternative.
It did, however, fall just short of its other benchmark. The Reference Portfolio, a notional low-cost mix of 80 percent global shares and 20 percent fixed interest that the Guardians use to measure whether their active decisions are worth the fees, returned 14.27 percent. The Fund lagged it by a tenth of a percentage point, a shortfall worth about $80 million. That is what happens when a narrow bet on global equities wins big and a broader portfolio cannot quite keep pace.
Townsend said the Fund’s spread of assets, which takes in timber, real estate and private market holdings as well as listed companies, had performed exceptionally well to deliver such a strong result in the current market. “In the short term, a concentrated portfolio can achieve strong results; however, over the long-term, we firmly believe a more diversified portfolio is better suited to our mandate,” she said.
Over 20 years the argument has held up. Townsend said the Fund had generated $22 billion over and above the passive benchmark across that period. “To put it another way, during that period the Fund has achieved an annual average return of 9.68 percent, as opposed to the Reference Portfolio’s annual average return of 8.19 percent,” she said. Since the Fund began investing in 2003 it has averaged 10.26 percent a year.
The Guardians are nonetheless telling everyone to expect less. Earlier this year they cut the Fund’s long-term expected annual return from 7.8 percent to 7.2 percent, a decision Townsend said reflected both a view that equity returns will soften and a deliberate reduction in how much active risk the Fund takes. “Returns for US equities over the past couple of years are close to double annualised returns for the past 20 years, so we would expect there to be some reversion to the mean at some point,” she said.
That downgrade is not an academic exercise. The forecast size of the Fund is one of the inputs Treasury feeds into the model that decides how much the Government must put in each year and when it can start taking money out. A lower expected return means the Fund grows more slowly, which means the Crown has to tip in more and wait longer.
The effect showed up in Budget 2026. Finance Minister Nicola Willis said in May that contributions were forecast to total $3.1 billion over four years, $2.2 billion more than had been expected at the Half Year Update in December, rising from $562 million in the coming financial year to just over $1 billion in 2029/30. “Updated population projections, new inflation forecasts and other changes to formula inputs mean we are continuing to make contributions over the next few years, rather than drawing down from the Fund as expected in last year’s Budget,” Willis said. Withdrawals are now expected to begin in 2054. When the Fund was set up, the first drawdowns were pencilled in for 2036.
Townsend said lowering the expected return did not change how the Guardians will be measured. “We will continue to be judged according to whether we deliver more value for taxpayers than would be generated by the Government using the Fund’s assets to pay down debt, and whether our long-term returns outperform a passive strategy with an equivalent risk appetite,” she said.
It is worth keeping the scale in view. The Fund is not there to pay the pension. It exists to smooth the cost of New Zealand Superannuation across generations, and it is small next to the bill it is meant to help with. Budget forecasts have the cost of the pension growing from $24.7 billion in the current financial year to $31.2 billion in 2029/30. At $94.4 billion the entire Fund would cover under four years of payments at today’s rate, and the whole point is that it is never spent that way.
The Fund has also lost years it will not get back. Contributions were suspended by the National-led government in July 2009 during the global financial crisis and did not resume until December 2017, by which point the Fund was worth $37.5 billion. The Guardians estimate the missed contributions over that period came to around $12.5 billion, with roughly $12 billion in forgone returns on top and about $3 billion in tax the Crown never collected as a result. Total government contributions since 2003 stand at $27.43 billion, against $13.66 billion in New Zealand income tax paid back.
The figures released this week are provisional and unaudited. The audited numbers appear in the Guardians’ annual report later in the year. Coverage of the result has also run at RNZ and interest.co.nz.
What do you make of it? Should the Government be putting more into the Fund while the pension bill climbs, or is a sovereign wealth fund that pays more tax than it receives already doing its job? Leave a comment below.
