The New Zealand dollar was confined in a narrow range ahead of the release of the December quarter consumer price index (CPI) this morning.
The kiwi was at 84.10 US cents at 8am, up from 83.93 US cents at 5pm on Thursday.
"It traded in a 40 point range at best overnight ," Mike Jones, from the sales team at BNZ said.
There was potential for the CPI data to set the market alight, particularly if inflation was low, he said.
The market is expecting a 0.1 per cent rise in the CPI, taking the annual rate to 1.2 per cent.
