The New Zealand dollar fell against the greenback as China, the fastest-growing major economy, cut its growth target to the lowest level since 2005, sapping demand for growth-linked assets including the kiwi.
The New Zealand dollar fell to 82.09 US at 8am from 82.75 US cents at 5pm yesterday. The kiwi declined to 66.75 yen from 67.58 yen.
China, New Zealand's second-biggest trading partner, cut its 2012 growth target to an eight-year low of 7.5 per cent from 8 per cent, a sign that its leaders are determined to cut reliance on exports and capital spending in favour of consumption.
"That was really what knocked back the New Zealand dollar and the Australian dollar," said Nick Tuffley, chief economist at ASB.
China comfortably surpassed the 8 per cent target set in the previous eight years and still plans to aim for inflation of about 4 per cent, unchanged from 2011.
