The New Zealand dollar fell, after dairy product prices dropped 8.8 per cent in the latest GlobalDairyTrade auction, on concern weaker prices for the country's largest commodity export could dent future economic growth.
The kiwi slid to 73.16 US cents at 8am in Wellington from 73.55 cents at 3am ahead of the auction result, and 73.79 cents at 5pm yesterday.
The trade-weighted index declined to 77.35 from 78.09 yesterday.
The New Zealand dollar weakened after dairy product prices dropped in the latest auction amid expectations that the supply of milk powder will not be as constrained as previously thought, and weak demand after officials last week detailed threats to poison New Zealand infant formula.
That caused the AgriHQ Seasonal Farmgate Milk Price for the 2014-15 season to drop to $4.60 per kilogram of milksolids, below Fonterra Cooperative Group's $4.70/kgMS forecast and prompted some analysts to question forecasts for a higher $6/kgMS payout in the upcoming 2015/16 season.
