The Australian and New Zealand dollars were on the defensive on Friday after a rough week in which worries about China's economy and asset markets drove both currencies to multi-month lows. The Aussie dollar was down 1.2 percent for the week at $0.7340 and within a whisker of a one-year trough at $0.7323. It still has some support around the $0.7329 low from May last year, but bearish charts flag the risk of a return to the December 2016 nadir of $0.7160.
The kiwi was pinned at $0.6743, having shed 2.4 percent in a week that saw it delve depths not visited since June 2016 at $0.6739.
