The New Zealand dollar rose ahead of a speech by Reserve Bank governor Graeme Wheeler, on speculation he may soften his language about an easing bias, and after stocks rebounded and commodities gained.
The kiwi dollar rose to 66.77 US cents as at 8am in Wellington, having earlier gained to as high as 67.08 cents, from 66.61 cents late yesterday.
The trade-weighted index rose to 71.01 from 70.90.
Stocks on Wall Street rallied overnight, sending the Standard & Poor's 500 Index up more than 1 per cent, while the Thomson Reuters/Jefferies CRB Index rose about 0.8 per cent, easing concern the slump in Chinese equities would continue to weigh on global markets.
Locally, Wheeler is due to give a speech on the economy to a private briefing, with notes released at 9am this morning. It will be his first since last week cutting the official cash rate to 3 per cent, while saying that "softening in the economic outlook" meant "some further easing seems likely."
