The NZX 50 Index extended gains to a new record, led by Xero which reached a fresh high after being included on an Asia-Pacific index, and Air New Zealand which continued to rise on post-earnings optimism.
The benchmark index rose 41.701, or about 0.8 percent, to 5114.791. Within the index, 27 stocks rose, 13 fell and 10 were unchanged. Turnover was $170.6 million.
"The whole New Zealand market is going nuts at the moment," said Greg Easton investment advisor at Craigs Investment Partners. Investors were drawn to the potential of growth and good economic indicators in the New Zealand market, as opposed to more risky emerging market options, he said.
Xero climbed 4.4 percent to $44.49, with an intraday high of$45.99. The Wellington-based accounting software stock was included on a FTSE Asia-Pacific, excluding Japan, mid-cap index.
Air New Zealand climbed 3.2 percent to $1.915, a six-year high. The national carrier lifted first-half earnings by controlling costs and said full-year profit would rise more than 17 percent.
