The New Zealand dollar rose after the nation's terms of trade rose to their second highest level ever in the September quarter.
The domestic currency's gains were buttressed by downbeat data in Australia on housing consents and job advertisements.
The kiwi was trading at 64.46 US cents at 5pm in Wellington from 64.30 at 8am while the trade-weighted index was at 71.48 from 71.31.
New Zealand's terms of trade, a measure showing the purchasing power of New Zealand's exports relative to imports, jumped 1.9 per cent in the three months ended September, nearly double the 1 per cent gain economists had been expecting and the largest quarterly increase since March 2016.
The terms of trade are now within a whisker of their record level set in December 2017.
