The S&P/NZX 50 index closed 0.4% higher at 12,655 on Tuesday, extending recent gains and starting the first trading day of the month on a positive note, led by health stocks and non-energy mineral shares. Investors continued to weigh the global impact of US tariff policies, with the 90-day reprieve set to expire next week. Treasury Secretary Scott Bessent said some countries are “negotiating in good faith” but warned tariffs could “snap back” to April 2 levels if talks stall. Meanwhile, private data showed China’s manufacturing sector returned to expansion, easing concerns over risks to Kiwi exports given the countries’ close trade ties. Among health stocks and non-energy mineral shares, gains were led by Fisher & Paykel (+2.6%), AFT Pharmaceuticals (+1.1%), Fletcher Building (+2.1%), Santana Minerals (+2.7%), and Arborgen Holdings (+1.6%).
