The New Zealand dollar declined against the Australian dollar ahead of the Reserve Bank of Australia's decision on interest rates today.
The kiwi touched 90.82 Australian cents overnight, and was trading at 90.23 cents at 8am in Wellington, from 90.26 cents at 5pm yesterday.
The local currency slipped to 65.70 US cents from 65.89 cents yesterday. The trade-weighted index was at 70.30 from 70.31 yesterday.
Australia's Reserve Bank is likely to keep interest rates on hold today, according to 25 out of 28 economists in a Bloomberg poll.
While RBA governor Glenn Stevens is expected to keep the rate at 2 per cent, traders will be closely watching the tone of his statement for signs of potential weakness ahead.
