It fell against the Australian dollar after the Australian Bureau of Statistics said private new capital expenditure rose a seasonally adjusted 1 per cent in the third quarter. Rising iron ore and rebar prices also helped shore up the Aussie.

The rising metals "saw the Aussie-kiwi outperform quite strongly and that kept the pressure on the kiwi as well," he said.
Looking ahead, Kelleher said investors will be watching for US jobless claims and core PCE price index data in particular, as it is the Federal Reserves' preferred measure of inflation.
