The New Zealand dollar gained along with other commodity-linked currencies as a pickup in prices of raw materials boosted sentiment ahead of the GlobalDairyTrade auction tonight.
The kiwi dollar rose to 72.08 US cents as at 8am in Wellington from 71.75 cents late yesterday. The trade-weighted index climbed to 76.33 from 76.07.
The Thomson Reuters/CoreCommodity CRB index, a broad measure of prices for raw materials, rose 1.3 per cent to a month-high of 185, while Brent crude oil gained about 3 per cent to US$48.41 a barrel.
Rising commodity prices tend to benefit the currencies of nations that export raw materials, such as Australia's iron ore, coal and crude oil and New Zealand's dairy, meat and logs. Dairy futures suggest whole milk powder will rise about 10 per cent in tonight's auction, adding to a 10 per cent gain in the last sale two weeks ago.
"USD remains out of favour and the commodity currencies have seen modest gains," said Jason Wong, currency strategist at Bank of New Zealand.
