The New Zealand Institute of Economic Research states that the free trade agreement with India functions primarily as strategic positioning in a fragmented global economy rather than an immediate export booster.
The Reserve Bank of New Zealand expects headline inflation to reach 4.3 per cent in the September 2026 quarter after the Strait of Hormuz disruption drives up fuel costs. Markets price an official cash rate peak of 3.7 per cent by the end of 2027, above the central bank's conditional 3.2 per cent path.
New Zealand's gross domestic product is forecast to grow between 0.7 and 1.0 percent in the March 2026 quarter on a seasonally adjusted basis. Stats NZ will release the official figures on 18 June 2026.
The December 2025 quarter recorded 0.2 percent growth. The positive print would follow modest momentum from the prior quarter, with timely indicators such as retail spending pointing to continued expansion.
Westpac and ANZ both forecast 1.0 percent growth for the March quarter. Kiwibank predicts 0.7 percent while BNZ sees 0.7 to 0.9 percent. The RBNZ also projects around 1.0 percent. Seasonal factors are expected to add approximately 0.4 percentage points to the headline result.
Kiwibank economist Alexandra Turcu described the Q1 data as the calm before the storm. ANZ economist Matthew Galt noted that aligned growth would shore up prospects of an OCR hike in July.
Auckland's Viaduct Basin commercial precinct — the GDP data due Thursday will set the baseline for how New Zealand's economy entered the oil-shock era.

Oil Shock Clouds the Outlook
However the Middle East conflict has already disrupted oil supplies. Brent crude prices reached around $130 per barrel in March 2026 — up $60 per barrel from pre-conflict prices.
The RBNZ May 2026 Monetary Policy Statement incorporated the shock. It downgraded the near-term growth outlook, with annual GDP growth in 2026 now expected to be 0.9 percentage points lower than February projections.
Kiwibank economist Alexandra Turcu described the Q1 data as the calm before the storm.
Treasury's Budget Economic and Fiscal Update 2026 cut its 2025/26 growth forecast by 0.5 points to 1.2 percent. The 2026/27 forecast was reduced by 1.1 points to 2.3 percent.
Westpac revised its full-year 2026 forecast down to 1.9 percent. The OECD projects 1.4 percent growth for New Zealand in 2026. The IMF, in its post-conflict downgrade report released in April 2026, estimates 2.1 percent growth for New Zealand in 2026.
OCR Implications and the Road Ahead
A result near 1.0 percent would support the case for an OCR hike in July. ANZ economist Matthew Galt noted that aligned growth would shore up prospects of such a move. The RBNZ held the OCR at 2.25 percent in April. It signalled potential decisive hikes if inflation pressures persist.
Inflation is projected to peak above 4 percent in 2026 due to higher fuel costs. The full effects of elevated energy prices on consumption and investment will appear in Q2 GDP data due in September. That quarter may show contraction.
New Zealand's floating exchange rate and diversified economy provide some buffers compared with past oil shocks. Households face higher petrol and diesel prices while businesses confront increased input costs. The data will inform the RBNZ's July policy decision and Treasury revenue projections.
