The New Zealand dollar fell to its lowest in more than three weeks as the greenback soared after better-than-expected US jobs data boosted speculation the US Federal Reserve may raise interest rates as early as June.
The kiwi fell to 73.40 US cents and was trading at 73.47 cents at 8am in Wellington, from 73.60 cents at the New York close and 74.93 cents at 5pm in Wellington on Friday.
The trade-weighted index declined to 77.17 from 78.14 on Friday.
The dollar index, which measures the greenback against a basket of currencies, jumped to its highest in 11 1/2 years after a report showed the US added 295,000 jobs in February, ahead of the 240,000 expected and the 12th straight month the economy added more than 200,000 jobs.
The US unemployment rate fell to 5.5 per cent, the lowest in more than six years and at the top of a 5.2 per cent to 5.5 percent range of what many Fed officials consider to be full employment.
