MELBOURNE/WELLINGTON, Feb 5 (Reuters) - Australian shares fell 0.7 percent by mid-session on Friday, led down by the big banks ahead of U.S. jobs and Chinese foreign exchange reserves data, and by consumer stocks on disappointing retail sales in December. New Zealand shares held steady.
The benchmark S&P/ASX 200 index .AXJO was down 38.5 points at 4,941.9 as of 0206 GMT, reversing nearly a third of Thursday's gains.
"People have been selling our banks -- it's more of a macro play. They're shorting the (Australian) dollar and shorting the Australian banks. We are the global play on China," said Chris Weston, a dealer at IG Markets.
As a major exporter to China, Australia's markets are often used by investors as a proxy for China, as they have limited access to Chinese markets.
Investors were positioning ahead of China's foreign exchange reserves report due on Sunday, watching to see how big an outflow of capital there was in January. If the outflow was bigger than expected, markets will turn more volatile.
"Anything linked to China will come off," Weston said.
Among the consumer stocks, APN News & Media APN.AX fell the most, down 7.5 percent, after rival News Corp NWS.AX NWSA.O reported a drop in quarterly earnings for the fourth quarter in a row. stocks helped limit the market's losses, with top global miner BHP Billiton (L:BLT) BHP.AX up 3.8 percent, top Australian gold miner Newcrest Mining NCM.AX up 4.4 percent and Alumina Ltd AWC.AX up 6 percent.
