GDP data confirms broad-based growth in Q1, but the clock has already moved on
New Zealand's economy grew 0.8% in the March 2026 quarter, according to Stats NZ data, confirming that a recovery was building before the Middle East conflict disrupted global energy markets. Annual GDP growth came in at 1.5% year-on-year — ahead of most forecasts — lifted by an upward revision to the December 2025 quarter from 0.2% to 0.5%.
The headline number carried more weight than it appeared. Westpac senior economist Michael Gordon noted that "the net impact of revisions to the recent history make this a stronger overall result than we were expecting," while ASB senior economist Kim Mundy confirmed that "the growth drivers were more diverse in Q1" — a sign that the recovery was no longer being carried by the rural sector and tourism alone.
Kiwibank economist Alexandra Turcu framed the result as a question of starting position: the economy was solid coming into the oil crisis, but not so strong as to send inflation fears soaring.
That distinction matters — an economy with modest but broadening momentum, hit by a supply-side shock, is a different environment to one running hot, and it shapes how aggressively the RBNZ is likely to respond.
A recovery that was broader than expected
The breadth of the March quarter recovery is what makes the data significant, even if it is now dated. Growth was not concentrated in one sector — manufacturing rose 1.9%, wholesale trade expanded 2.4%, retail trade and accommodation grew 1.2%, and business services added 1.1%. Investment in plant, machinery, and equipment jumped 5.5%, with Turcu noting that computing and technology purchases were a notable driver, suggesting early signs of AI-related capital expenditure flowing through the data.
The drag came from construction, which fell 1% for the second consecutive quarter and sits 3.8% lower on an annual basis. Residential investment fell 3.1% over the quarter, and private consumption rose only 0.5%, constrained by a soft labour market and subdued house price growth.
What the GDP result means for the OCR
This data captures a three-month window that closed before the Middle East conflict began, and the picture since has shifted considerably.
NZIER continues to forecast the RBNZ will begin raising the OCR in July, with a follow-up hike in September — a view shared by ASB, which "still favours a July start to OCR hikes and a 3.25% OCR peak by year end." A move from the current 2.25% to 3.25% would represent 100 basis points of additional tightening, with mortgage rates expected to follow that trajectory higher across most fixed terms.
The RBNZ's response will depend far less on the March GDP result than on how the June and September quarters unfold — how much demand the fuel price shock destroyed, how durable the Middle East peace agreement proves, and whether inflation expectations become embedded.
