New Zealand shares dropped, led by Auckland International Airport, as institutions sold shares to participate in the selldown of the nation's busiest gateway. Hallenstein Glasson and Steel & Tube gained after posting better earnings.
The NZX 50 Index fell 42.46 points, or 1 percent, to 4196.73. Within the index, 29 stocks fell, 10 rose and 11 were unchanged. Turnover was $474 million, making it one of the busiest days this year, reflecting the NZ Superannuation Fund's selldown of its Auckland Airport stake.
Auckland Airport dropped 5.8 percent to $2.77. The so-called Cullen Fund sold 7.6 percent of the airport company at $2.76 apiece overnight, a 6 percent discount to where it ended up the previous day, when it closed at $2.94, the highest since November 2007.
The selloff was driven by "the massive placement in Auckland Airport", says Matt Goodson, portfolio manager at BT Funds Management. "Stocks needed to be sold to raise funds to participate" and the impact was seen across the market.
