Traders are pricing in a 73 percent chance of a rate cut on Tuesday, according to the Overnight Index Swap Curve.
"With the interest rate differential, if they do cut rates there's a high chance we will see parity" between the kiwi and the Australian dollar, said Stuart Ive, senior dealer at OMF. "I find it hard to believe it will be sustained though."
Ahead of the RBA, US non-farm payrolls due out Friday in the US are expected to show the world's biggest economy added 245,000 jobs last month, although the the ADP National Employment Report on private payrolls showed a lower-than-expected gain of 189,000 last month, the lowest in 14 months.
"The expectation is for a very good number. If it fails to deliver, then the US dollar could be punished," Ive said. Any moves could also be amplified by reduced trading during a holiday period.
"The market is long US dollars. Whether the Federal Reserve raises in June or September, interest rates are going up in the US."
The kiwi actually gained overnight after prices for dairy products fell an average 10.8 percent in the latest GlobalDairyTrade auction, with many in the market anticipating an even weaker sale.
The currency was little changed at 69.28 euro cents from 69.32 cents yesterday. Ive said next week is key for the euro because the deadline for Greece to repay 450 million euros of debt is April 9 and any disruption could see the euro drop sharply initially.
The kiwi slipped to 89.29 yen from 89.38 yen yesterday and was little changed at 50.31 British pence from 50.29 pence.
