The New Zealand dollar was testing 84 US cents in early trading after having a strong session overnight as the US dollar weakened.
The kiwi was at 83.94 US cents at 8am, up from 84.02 US cents at 5pm on Monday. It traded as high as 84.30 overnight.
Support at 83.60 cents held on Monday so the kiwi resumed its upward trend.
The NZIER Quarterly Survey of Business Opinion and a residential property market report this morning will provide fresh information on the state of the economy, but a speech by US Federal Reserve boss Ben Bernanke at the same time may be of more interest to traders.
"There have been some Fed guys speaking overnight. They are going down the line that the US economy is improving but the path is still not clear," Stuart Ive, currency strategist at HiFx said.
