Asian stock markets wavered Friday on renewed expectations for a Fed rate hike this year while the New Zealand dollar jumped on prospects of increased dairy exports after China abolished its one-child policy, AP reported. Japan's Nikkei 225 was up 0.8 percent to 19,083.10 after the Bank of Japan left its super-easy monetary policy unchanged. Hong Kong's Hang Seng was down 0.5 percent at 22,706.48 and South Korea's Kospi fell 0.2 percent to 2,029.47. China's Shanghai Composite was little changed at 3,387.73. Australia's S&P/ASX 200 fell 0.5 percent to 5,239.40. Stocks fell in Singapore, the Philippines and Indonesia, but rose in Thailand. The New Zealand dollar surged in the wake of China's announcement it would allow all couples to have two children, abolishing its unpopular one-child policy. New Zealand is a major dairy exporter and its milk powder and formula industry is likely to benefit from a baby boomlet in China. The kiwi dollar jumped to $0.6755 from $0.6699 the day before. Shares of baby-related stocks also posted big gains. The Dow Jones industrial average fell 23.72 points, or 0.1 percent, to 17,755.80 on Thursday.
