The New Zealand dollar gained after better manufacturing data from China boosted investor confidence about growth in Asia's largest economy and as prospects fade for imminent western military action in Syria.
The kiwi advanced to 77.60 US cents at 8am in Wellington, from 77.19 cents at the New York close and 77.70 cents at 5pm in Wellington on Friday. The trade-weighted index was little changed at 73.61 from 73.67 in Wellington Friday.
Over the weekend, a Chinese manufacturing gauge for August rose to a 16-month high, bolstered by new orders and overseas demand, prompting some economists to raise their estimates for third quarter economic growth in the world's second-largest economy. China is New Zealand's second-biggest trading partner after Australia, which counts China as its largest trading partner.
"It shows a bit of a rebound going on in China," said Tim Kelleher, head of institutional FX sales in New Zealand for ASB Bank. "Also, there has been no military action in Syria, which has calmed down things a bit. The risk on the day is probably on the upside."
The New Zealand dollar will likely trade up to the top of its recent range of 78 US cents today, while the Australian dollar may rise to 90 US cents, from 89.39 US cents at 8am, Kelleher said.
