The New Zealand dollar rose along with other commodity currencies after the Australian Reserve Bank chose not to cut interest rates yesterday and following better-than-expected growth data in Canada.
The kiwi increased to 75.58 US cents at 8am in Wellington, from 75.26 cents at 5pm yesterday.
The trade-weighted index gained to 78.52 from 78.28 yesterday.
The currencies of countries reliant on commodity exports advanced overnight after the RBA opted to leave its interest rate unchanged at a record low 2.25 per cent, and a report showed Canada's economy grew at an annualised rate of 2.4 per cent in the fourth quarter, beating the 2 per cent expected.
Meanwhile, average prices advanced 1.1 per cent at the GlobalDairyTrade auction overnight, keeping Fonterra Cooperative Group's forecast payout to dairy farmers this season intact.
