SYDNEY/WELLINGTON, Dec 7 (Reuters) - The Australian dollar slipped to more than two-week lows on Thursday after data showed the country's trade surplus slumped in October on weaker iron ore prices, while its New Zealand cousin remained within recent ranges.
The Australian dollar AUD=D4 fell 0.3 percent to as low as $0.7542 after data showed the trade surplus shrank to A$105 million ($105.00 million), down from A$1.6 billion in September and expectations of A$1.4 billion. still managed to notch up 12 straight months of surpluses, the longest streak since 2011.
Iron ore is Australia's top export earner so Thursday's data points to a disappointing start for the final quarter of 2017, particularly after exports made zero contribution to gross domestic product (GDP) last quarter.
Still, exports likely bounced back in November following a recent surge in iron ore prices. The most-traded Dalian iron ore contract DCIOcv1 jumped 16.5 percent last month alone.
Economists were still uncertain about whether volumes would pick up as an industrial pollution crackdown in China, which has dented demand and prices, remains in place.
"Overall, it's possible that the total trade surplus will turn into a deficit in the coming months, at least for a short while," said Paul Dales, chief economist at Capital Economics.
"And while it is early days yet...net exports may be a small drag on GDP growth in the fourth quarter."
Across the Tasman Sea, the New Zealand dollar NZD=D4 was steady at $0.6879. It has been trapped in a narrow range of $0.6830 to $0.6913 since the end of November.
