The New Zealand dollar gained half a cent against the greenback as better-than-expected manufacturing in the US and China underpinned optimism the world's two largest economies are back on track.
The kiwi rose as high as 82.54 US cents in Northern Hemisphere trading and traded at 82.36 cents at 8am, up from 81.96 cents yesterday at 5pm. The trade weighted index increased to 73.19 from 72.98.
Investors' appetite for higher-yielding assets was stoked after US manufacturing figures showed the sector expanded at a faster pace than forecast in March. The Institute of Supply Management's factory index rose to 53.4 from 52.4 a month earlier. Fifty is the dividing line between growth and contraction. Economists in a Bloomberg survey had predicted the gauge would climb to 53.
That followed on from official Chinese manufacturing figures, which showed industrial activity is still expanding after HSBC's lead indicator raised fears it may be contracting.
"The data effectively gave the New Zealand dollar another growth signal," said Alex Sinton, senior dealer at ANZ New Zealand. "What the market wanted was a back-up to the Chinese data."
