Fiscal Reality Check: Treasury Pushes Surplus Past 2029 as National’s Debt Goal Slips1

By Lions Roar News Business & Finance Team

WELLINGTON, NZ – New Zealand’s economic recovery is proving to be slower and more painful than anticipated, pushing the government’s long-sought return to a fiscal surplus further into the future. The grim outlook, delivered in the Treasury’s Half-Year Economic and Fiscal Update (Hyefu) released this week, confirms that Finance Minister Nicola Willis will be presiding over deepening deficits for the foreseeable future, while the national debt pile continues its upward climb.

The Hyefu report paints a sobering picture: the traditional measure of the operating balance (Operating Balance Before Gains and Losses, or OBEGAL) is now not expected to reach a surplus until the very end of the forecast horizon, with a minimal $60 million surplus predicted in 2029/30.² This timeline severely undercuts the Government’s pre-election commitment to return the books to surplus by $2026/27, marking a significant political setback.

📉 Deficit Deepens Before Any Recovery

The immediate forecast shows the country’s deficit worsening before it can be repaired.³ Treasury sees the deficit widening from an expected $14.0 billion in the year to June 2025 to a whopping $16.9 billion in 2025/26.

The Treasury report states the economy has been “slow to recover from a deep cyclical downturn.” This prolonged stagnation is attributed to the necessary high interest rates imposed by the Reserve Bank to curb inflation—a policy that intentionally engineered a recession.

While the Reserve Bank has now eased its stance, the Hyefu points to external factors prolonging the pain: “Uncertainty around global trade policy has exacerbated the lasting impact of high interest rates and has dampened consumer spending, business profitability and investment activity.”

Consequently, the forecast for economic recovery has been marginally slowed compared to the May Budget. Nevertheless, the Treasury still projects annual Gross Domestic Product (GDP) growth to lift from $-0.6\%$ in 2024/25 to a robust $3.3\%$ in 2025/26 and $3.0\%$ in 2026/27, suggesting that while the immediate future is bleak, an upswing remains on the cards.

💰 The Debt Curve: Peak Higher and Later

The slippage in the surplus target has a direct impact on the national debt.⁴ Net core Crown debt is now expected to be marginally higher than the Budget forecast and continue its upward trend.

• Net Core Crown Debt Forecast: Debt is projected to climb from ⁵$41.8\%$ of GDP in 2024/25 to a peak of ⁶$46.9\%$ of GDP in ⁷$2027/28$ and ⁸$2028/29$.⁹

This peak is higher and later than previously forecast. Finance Minister Nicola Willis’s publicly stated fiscal strategy committed to putting the debt-to-GDP ratio on a downward trajectory toward ¹⁰$40\%$ over the longer term.¹¹ The latest figures show that goal becoming more challenging to achieve.

Surplus Goal Watered Down

In response to the Treasury’s bleak outlook, Minister Willis has been forced to adjust her own target for returning the books to surplus using her preferred measure, “Obgealx” (Operating Balance Before Gains and Losses, excluding the impact of ACC).

Her original goal was to achieve an Obgealx surplus by ¹²$2027/28$.¹³ She has now softened this target, aiming for surplus a year later, in ¹⁴$2028/29$.¹⁵ Crucially, Treasury’s independent forecast sees even this adjusted goal being missed, with the Obgealx measure only returning to surplus by ¹⁶$2029/30$.¹⁷

Secretary to the Treasury Iain Rennie noted that the path back to balance is a two-pronged effort. He estimates that approximately one-third of the Obgealx deficit will narrow naturally as the economy recovers and enters a more favourable part of the cycle.¹⁸ The remaining two-thirds of the deficit reduction must come from deliberate government action:

• Limiting expenditure growth.
• Improving the financial performance of large Crown entities like Kāinga Ora and Health New Zealand.
• Rising tax revenue as a percentage of GDP, partially driven by wage inflation pushing individuals into higher tax brackets.¹⁹

💸 Borrowing Binge and Budgetary Constraint

The ongoing deficits mean the Government must continue to borrow heavily.²⁰ New Zealand Debt Management has slightly increased its forecast bond issuance programme, planning to issue $135 billion of New Zealand Government Bonds in the four years to $2028/29$ (up from $132 billion previously).

This level of debt issuance is starkly higher than the pre-Covid era, when the government issued around $8 billion of bonds per year. The debt load is being driven by several concurrent factors:

• Renewing Covid-era debt: The government is unable to pay off the massive debt accumulated during the pandemic.
• New Debt: Issuing new debt to fund initiatives and cover operating deficits.²¹
• Interest Costs: Servicing the interest bill, which is now worth approximately $9 billion annually.
• Quantitative Tightening: The Reserve Bank’s unwinding of its money printing (quantitative easing) programme requires the Government to issue more debt to mop up liquidity.

Despite the fiscal pressures, the Finance Minister confirmed a highly constrained Budget 2026, limiting operational expenditure increases to just $2.4 billion and capital expenditure to $3.5 billion.²² Given the existing cost pressures across public services, this modest operating allowance suggests that most agencies will face another year of finding efficiency savings, and potentially real-terms cuts, to manage service demands.²³ While Minister Willis declined to detail major spending cuts, significant changes to the Accident Compensation Corporation (ACC) that could save the government money are expected to be announced in the coming days.

Ultimately, the Hyefu confirms that the Government faces a protracted battle to restore the nation’s finances, pushing politically significant milestones for surplus and debt reduction several years beyond initial public promises. The price of the current economic environment, initially driven by the fight against inflation, is turning out to be a sustained period of high debt and fiscal restraint.
