Treasury lifts NZ deficit outlook but productivity remains the 'elephant in the room'

Pre-election update shows smaller borrowing forecasts while long-term growth challenge persists

New Zealand's Treasury has handed parties an improved near-term fiscal picture ahead of November's election, forecasting a $6.8 billion deficit for 2026-27, down from the $11.4 billion predicted in May, but economists warn the country's long-running productivity slowdown remains unresolved.

The Pre-Election Economic and Fiscal Update, released yesterday, gives political parties a clearer sense of the economy they could inherit. Treasury now expects lower government borrowing by $15 billion over the next four years thanks to higher tax revenue. Inflation has climbed back to 4.1 percent annually, and the global oil shock is flagged as a renewed risk to growth and prices.

GDP rose 0.2 percent in the June quarter, following 0.9 percent growth in March, and was 1.7 percent higher than a year earlier. That marks a return to growth after a period of weak performance and high inflation in 2023.

But the recovery remains fragile, and Treasury's own estimates show productivity growth averaged around 1.4 percent a year between 1993 and 2013, then slowed to just 0.2 percent a year over the following decade. University of Otago economics professor Dennis Wesselbaum, writing in The Conversation, describes this as the 'elephant in the room' that neither an economic recovery nor a change of government can quickly fix. Higher productivity is what allows wages and living standards to rise without longer working hours, and it funds public services from health to superannuation.

With the campaign trail now active, the update gives parties a firmer basis for costing their promises, but the underlying productivity problem remains largely absent from election pledges.

Analysis

Why This Matters

  • The improved deficit forecast gives the next government more fiscal headroom, but also more room to make un-costed promises that could worsen long-term debt.
  • Productivity growth near zero means the gains that usually fund public services and higher living standards are simply not being generated, a problem no single budget can solve.
  • The oil shock risk means inflation could stay above target, complicating the Reserve Bank's task and squeezing household budgets.

Background

New Zealand's economy has swung from weak growth and high inflation in 2023 to a modest recovery, with two consecutive quarters of GDP growth this year. The Treasury's pre-election update is a standard part of the electoral cycle, designed to give parties and voters an independent snapshot of the fiscal outlook. But the productivity slowdown is a deeper, structural issue that predates the current cycle. For decades New Zealand has trailed other advanced economies on measures of output per hour, and the sharp drop in productivity growth over the past decade has made that gap harder to ignore.

Key Perspectives

Treasury officials: They point to an improving deficit and higher tax revenue, while warning that oil price shocks remain a key risk to inflation and growth. Their forecasts frame the near-term recovery as real but fragile. Economists like Dennis Wesselbaum: They argue the recovery masks a more serious long-term problem. Without productivity growth, wage gains and public services cannot be sustained, and this issue deserves more attention in the election campaign than it is getting. Political parties: The article suggests election pledges have mostly avoided productivity, focusing instead on more immediate tax and spending commitments. Parties may prefer to campaign on the improved deficit than on the harder structural questions.

What to Watch

  • Whether any party releases a concrete productivity plan before the November election, and whether Treasury revises its forecasts after the oil shock.
  • The next inflation data, which will show whether the 4.1 percent rate is falling or heading back up.
  • How the improved borrowing track affects election promises, particularly any new spending or tax cuts announced in the final weeks of the campaign.
