The NZX 50 fell 17 points, or 0.1%, to close at 13,739 on Friday, reversing gains from morning trading and ending a two-session advance. Investors continued to assess Thursday’s GDP data, which showed New Zealand’s economy grew faster than expected in the second quarter on both annual and quarterly measures, although quarterly growth eased to 0.1% from 0.2%. Traders were also looking ahead to China’s interest-rate decision and US PMI data next week for indications about the economic outlook in both countries. The latest domestic data limited gains: New Zealand’s trade deficit narrowed in August from July, while food inflation remained at a 19-month low. A rally on Wall Street on Thursday helped cushion the decline, with lower oil prices also softening Treasury yields. Consumer staples, financials and communication services were the main drags. A2 Milk fell 3.9%, Skellerup Holdings dropped 2.9%, Gentrack Group declined 2.6%, Infratil lost 1.0% and Westpac Banking Corp eased 0.9%.
