Sky Network Television led the benchmark index higher, up 2.1 percent to $6.26. On Friday, the country's dominant pay television provider said it had renewed its five-year contract for the broadcasting rights for rugby and said it expected annual profit to grow as much as 8.6 percent to $180 million in 2015.
Fisher & Paykel Healthcare climbed 1.7 percent to a record close of $5.55. The breathing apparatus manufacturer and exporter is expected to report earnings for the six months ended Sept. 30, which should be bolstered by about a 13 percent decline in the New Zealand dollar against the US greenback from its 88.35 US cent peak in July.
"It's momentum ahead of results," Smalley said. "Momentum begets momentum, and people are buying up ahead of results, the question is will they buy the rumour to sell the fact?"
NZX rose 1.7 percent to $1.17 after Orion Health Group lodged its prospectus for an initial public offer, seeking to raise up to $155 million. The software developer has flagged a dual-listing on the NZX and ASX in late November.
Guinness Peat Group was the benchmark index's worst performer on the day, dropping 9.1 percent to 50 cents. Its Coats unit reported flat sales in the third quarter, affirming expectations annual profit will meet market forecasts. GPG is in the process of rebranding as Coats after liquidating its broader portfolio, though that's been delayed by protracted negotiations to settle its group pension liability with the UK Pensions Regulator.
"It's a serial underperformer and the big sword of Damocles hanging over its head is that pension scheme," Smalley said. Because UK interest rates remain low, the cost of its pension scheme is now surpassing the interest it earns, making it a more expensive problem, Smalley said.
