Some 17 out of 23 analysts expect the RBA to cut its cash rate by 25 basis points to 1.5 percent by August, according to a Bloomberg survey, while traders are pricing in a 78 percent chance of a 25 basis point cut by the RBNZ in June, and a more than 50 percent chance of a follow-up 25 basis point cut by November, according to the overnight interest rate swap market.
"With the RBA expected to struggle to reach its inflation target over the next couple of years, a number of analysts changed their calls to predict further rate cuts," Bank of New Zealand currency strategist Jason Wong said in a note.
"The New Zealand dollar fell in sympathy, with investors concluding that with the same forces affecting New Zealand, further RBNZ easing was also more likely."
The greenback held up on Friday in the US, even after a weaker-than-expected US non-farm payrolls release that showed the world's biggest economy added 160,000 jobs last month, compared with expectations of about 200,000, with concern about the headline number offset by figures showing annual wage inflation beat estimates at 2.5 percent.
The New Zealand dollar slipped to 92.59 Australian cents from 92.71 cents on Friday, fell to 59.78 euro cents from 60.10 cents, sank to 4.4271 yuan from 4.4578 yuan, declined to 72.94 yen from 73.43 yen and edged lower to 47.26 British pence from 47.33 pence
