Australian and New Zealand dollars tumble

The Australian and New Zealand dollars ground to multi-week lows on Tuesday, weighed by persistent global growth concerns with investors waiting for concrete action from policymakers in the United States and Europe. The Aussie dollar plumbed one-month lows against both the US dollar and yen, undermined by Japanese sales. It dipped to $1.0345, its weakest since late July, to last fetch $1.0360.
The Australian dollar was nursing chunky losses against a broadly stronger yen. It skidded to 81.25 yen, its weakest since late July, and looked set to test 81.04, the 61.8 percent of the 79.49-83.57 move. The New Zealand dollar fell to a two-week low of $0.8057 from $0.8082.
