The kiwi came under renewed pressure when New Zealand business confidence hit a seven-year low in June as cost pressures weigh on profitability and the downbeat sentiment is beginning to impact on future planning.
The weak sentiment has led economists to lower their expectations for economic growth and to continue to speculate on a possible rate cut by the central bank.
"Weak business confidence and the risk it presents to GDP growth over the rest of 2018 suggests the odds of a rate cut (rather than hike) are growing," said ASB Senior Economist Jane Turner.
The RBA kept rates on hold and continued to signal that rates would be on hold for some time to come.
The RBA does expect an acceleration in wages growth and inflation over time, but the process will be slow.
"The low level of interest rates is continuing to support the Australian economy. Further progress in reducing unemployment and having inflation return to target is expected, although this progress is likely to be gradual," it said in a statement.
Looking ahead, investors will be watching for the minutes from the US Federal Open Market Committee as well as jobs data later in the week. Trading, however, will be quiet due to the July 4 Independence Day Holiday.
