New Zealand shares extended their gains on the back of improved sentiment in the US. Exporters including Fisher & Paykel Healthcare and A2 Milk benefited from a weaker kiwi dollar.

The S&P/NZX 50 Index rose 66.9 points, or 0.7 per cent, to 10,071.74. Within the index, 29 stocks gained, 15 fell, and six were unchanged. Turnover was $110.6 million.

The New Zealand market followed international cues as Wall Street set the tone. The Nasdaq and S&P 500 closed at records as better-than-expected earnings results and strong housing data allayed concerns that the US economy may be slowing. Stocks across Asia were mixed, with Australia's S&P/ASX 200 index up 0.9 per cent in afternoon trading, Singapore's Straits Times index rising 0.2 per cent while South Korea's Kospi Composite dropped 1.3 per cent.

David Price, a broker at Forsyth Barr, said New Zealand's market was following those international leads, but volumes were very light in the holiday-shortened week with little news to drive direction.


"There hasn't been any negative news for a while, so the market is just going in the same direction where it left off previously," he said. "We're just a little boat bobbing in the sea at the moment."

Exporters continued to benefit from a weaker New Zealand dollar, which followed the Aussie lower as weaker-than-expected Australian inflation raised the prospect a rate cut across the Tasman.

A2 climbed 2.4 per cent to $16.46, F&P Healthcare was up 2.3 per cent at $15.99, and Sanford rose 0.7 per cent to $6.92.

Synlait Milk, which supplies A2, led the NZX50 higher, up 2.7 per cent at $10.70 on a volume of 66,000 shares.

Several of the electricity generator-retailers updated their production numbers ahead of the Easter shortened week, with Mercury NZ and Genesis Energy both downgrading their earnings outlooks due to dry weather in the central North Island and a shortage of gas supply. Mercury increased 0.4 per cent to $3.865 on a volume of 1.1 million shares and Genesis rose 0.3 per cent to $3.09.

Outside the benchmark index, Scott Technology rose 0.4 per cent to $2.50 after announcing plans to buy French technology company Normaclass for an undisclosed sum.

Trade Me Group, which is set to de-list next week following a successful $6.45-a-share takeover, was unchanged at $6.43. It announced Norwegian online media executive Anders Skoe will take up the chief executive role in July under its new ownership.

Fisher Funds-managed investment vehicle Kingfish fell 0.7 per cent to $1.41. Its manager said the vehicle had its best quarter in 13 years in March, as it quit a long-held position in Michael Hill International and increased its exposure to A2, F&P Healthcare and Mainfreight.
