New Zealand stocks climbed 63 points, or 0.5%, to 13,930 on Wednesday, their highest close since August 6, extending gains from the previous session as healthcare and communication services shares advanced. Sentiment was supported by positive earnings from some companies and expectations for more results, although a weaker Wall Street session overnight, driven by a selloff in chipmaker-related stocks, rising Treasury yields (returns on U.S. government debt) and higher oil prices, restrained the market's upside. Domestic cost data also pointed to firmer price pressures, with input prices rising 2.9% quarter-on-quarter in Q2 and output prices up 1.6%, the fastest increases since Q1 2025. EBOS Group jumped 8.0% after reporting a 4.7% increase in net profit for the full year ended June 30, 2026, Fletcher Building gained 6.2% after returning to profit from a loss in the previous quarter, and Spark NZ rose 3.3% ahead of its earnings release on Thursday.
