New Zealand shares fell, on weak offshore leads and local stocks giving up dividend rights, with Sky Network Television, New Zealand Refining Co and Mercury New Zealand declining.
The S&P/NZX50 Index dropped 40.51 points, or 0.5 per cent, to 8,432.63. Within the index, 21 stocks fell, 21 were unchanged, and eight rose. Turnover was $154 million.
"There has been a bit of a negative lead from offshore, quite a big deal didn't go through with Broadcom and Qualcomm in the US," said Greg Easton, investment adviser at Craigs Investment Partners.
US President Donald Trump blocked a planned takeover of chipmaker Qualcomm by Singapore-based rival Broadcom on grounds of national security, with the deal slated to create the world's third-largest microchip maker if it went ahead.
"That put some spooks through the market and that has flowed through into the rest of the world a little bit," Easton said. At 5:15 pm New Zealand time, the ASX 200 was down 0.8 per cent, Hong Kong's Hang Seng had fallen 1.3 per cent and Japan's Nikkei 400 had dropped 0.7 per cent.
