Spark shed 1.9 per cent to $3.665 while A2 Milk fell 1.4 per cent at $3.44, which McIntyre put down investors booking profit on recent gains in the stock.
Auckland International Airport lost 0.7 per cent to $6.89 despite positive passenger numbers. The company said total international passenger numbers, excluding transits, increased by 15 per cent to 861,292 in April 2017 from the same month a year earlier. However, news that the transport hub's Chinese visitor arrivals were down 10.1 per cent in April 2017, compared with April 2016, may have weighed on sentiment, McIntyre said.
Fisher & Paykel Healthcare shed 0.2 per cent to $10.08. Earlier, Macquarie Group lifted its 12-month target price on the stock by 7.3 per cent and kept its 'outperform' rating after the company's full-year revenue growth beat expectations and as a weaker New Zealand dollar weighs in the exporter's favour. McIntyre said the stock was weaker on some profit-taking as investors had taken positions ahead of the result.
Ebos Group was the leading gainer adding 1.7 per cent to $18.25 after it entered an agreement to acquire HPS, Australia's largest provider of outsourced pharmacy services to hospitals, for A$154m (NZ$164m). The acquisition is expected to increase Ebos's underlying earnings before interest, tax, depreciation and amortisation by at least 5 per cent in the 2018 financial year and will add to earnings per share from year one, it said in a statement to the New Zealand stock exchange.
"On the surface it looks like a pretty positive acquisition for Ebos and certainly will provide them with some synergy benefits throughout Australasia. The market likes it," said McIntyre.
Serko shares jumped 21 per cent to 46 cents after the online travel booking software firm said it boosted sales and scaled back spending, allowing it to almost halve its annual loss and affirm its target of making a profit in 2018.
Chorus also helped shore up the index, adding 1.1 per cent to $4.48. McIntyre said the company continues to benefit from its addition to the S&P/ASX 200 index, index-tracking investors have to hold the stock. "They are very bond-like as they pay a good solid income stream to investors," he said, adding there is likely some ongoing buying from institutional investors.
Xero added 1.5 per cent to $24 as it moves toward break even. McIntyre noted that the chief executive Rod Drury seems to be giving a series of presentations about the business which is also helping it get some momentum.
Fonterra Shareholders' Fund rose 1.5 per cent to $6.13. The dairy giant is expected to publish its final forecast for the season that is just ending as well as its opening forecast for the season that starts on June 1.
