The rebound in dairy prices adds to positive sentiment for the kiwi dollar, which offers a reasonably attractive yield in a world where many central banks have interest rates that are near zero or negative.
"Global milk supply has been tightening more quickly in recent months prompting buyers into action," said Con Williams, agri economist at ANZ Bank New Zealand. "Where to from here will crucially depend on new season milk volumes from New Zealand and how demand holds up in the face of higher prices."
The kiwi dollar was also helped by a weaker US dollar, after the US non-manufacturing ISM composite index fell more than expected to 51.4 from 55.5, a seven-month low, suggesting the services sector in the world's biggest economy isn't as robust as economists had thought.
The kiwi rose to 96.42 Australian cents from 95.92 cents, slipped to 75.63 yen from 75.82 yen and rose to 4.9454 yuan from 4.8878 yuan. It gained to 65.85 euro cents from 65.65 cents and rose to 55.19 British pence from 54.94 pence.
