The New Zealand dollar rose after a gain in Chinese equities boosted optimism, pushing global sharemarkets and commodities higher.
The kiwi increased to 63.48 US cents at 8am in Wellington, from 62.76 cents at 5pm yesterday. The trade-weighted index rose to 69.09 from 68.49 yesterday.
Global equity markets gained and commodity markets rallied overnight, triggered in part by a late surge in Chinese equities, amid optimism China's government will act to support its flagging economy.
That boosted investor appetite for currencies from commodity producing countries such as the kiwi, Aussie, Norwegian krone and Canadian loonie, and saw them reduce holdings of lower-risk currencies such as the yen and the Swiss franc.
"A rebound in the Chinese equity market and rebound in key commodity prices helped lift the mood in markets generally," Bank of New Zealand senior market strategist Kymberly Martin said in a note.
"In this backdrop, the 'commodity-linked' AUD, NZD, NOK and CAD were the strongest performers. By contrast, improved sentiment resulted in the 'safe-haven' JPY and CHF being shunned."
BNZ's Martin said the kiwi has support at 62.50 US cents and faces resistance above 64 cents.
