The New Zealand dollar rose above 72 US cents for the first time since the beginning of March as the nation's robust economic growth story lifted sentiment.
The kiwi rose to 71.87 US cents as at 8am in Wellington, and earlier touched 72.05 cents, from 71.56 cents late yesterday.
The trade-weighted index rose to 77.24 from 76.98.
The GDT price index rose 0.6 per cent in the GlobalDairyTrade auction overnight to US$3,395, marking the sixth consecutive gain, although whole milk powder fell.
The auction is just one of a number of positive indicators for New Zealand including terms of trade rising to a 44-year high in the first quarter, driven by prices of dairy and forest product exports. Business confidence rose in May, as did New Zealand commodity prices. By contrast, data on Friday showed the US economy isn't adding jobs as fast as expected.
