The Australian dollars is on track for a third straight weekly loss as speculators bet central banks of both countries could cut rates as early as next week.
The Australian dollar was down 0.5 per cent for the week on top of its hefty 1.7 per cent loss the previous one.
At 1508 AEST it was trading at 69.98 US cents after falling below the key psychological support of 70 cents
The New Zealand dollar was also off 0.5 per cent this week, identical with the hit it took the prior week.
The currency was last at 66.23 US cents, inching closer to a recent five-month trough of 65.81.
The antipodean currencies have been on a downhill track since mid-April on a combination of factors, including a stronger US dollar, weaker-than-expected domestic inflation and talk of policy easing in both countries.
Official figures released early on Friday showed Australian dwelling approvals slid more sharply than forecast in March, adding to views that the country’s economic momentum is slowing.
Traders will be looking at where the Aussie finishes on Friday, as a close below 70 cents would be the first since January 2016.

Traders are generally long Aussie against the kiwi dollar as they see a greater chance of a rate cut in New Zealand, with RBNZ Governor Adrian Orr decidedly more dovish than his RBA counterpart Philip Lowe.
As a result, the Aussie climbed 1.3 per cent against the kiwi in April.
Some of those long Aussie positions were unwound last week after the first-quarter inflation rate was lower than expected.
New Zealand government bonds were barely changed.
Australian government bond futures were little changed too, with the three-year bond contract off half a tick at 98.725. The 10-year contract was flat at 98.20.
