New Zealand’s NZX 50 fell 20 points, or 0.1%, to close at 13,561 on Monday, reversing a 0.7% morning gain and extending the previous session’s losses to reach its lowest level since June 26. Financial, communication-services and industrial shares led the decline as weaker U.S. stock futures, rising oil prices and concerns about AI safety weighed on sentiment. Domestic data provided some support, with BusinessNZ’s Performance of Services Index rising to 51.2 in August 2026 from 50.6 in July, its strongest services activity in eight months, while manufacturing growth eased and tourist arrivals reached a four-month high. Investors awaited New Zealand’s second-quarter GDP report, China’s economic data and the Federal Reserve’s monetary policy meeting later in the week.
