The New Zealand dollar was trading in a narrow range as traders waited for direction on Japanese monetary policy and for US markets to gear up again after the Martin Luther King holiday.
The kiwi was at 83.63 US cents at 8am on Tuesday, little changed from 83.60 cents at 5pm on Monday.
The currency traded in a relatively narrow range overnight due to the holiday in US markets and inauguration of President Barack Obama, one dealer said.
He said statements by the Bank of Japan later today were expected to be main event in markets today.
Economists in a Bloomberg News survey expect the central bank to expand asset purchases after a two-day meeting ends today.
