"It was a good result from Z, it's been interesting this week but they've continued onwards and upwards as they should," said David Price, director, institutional equities at Forsyth Barr. "They confirmed circa 10 per cent gross dividend yield for next year, which in the current low environment is pretty good."
Chorus rose 2.8 per cent to $4.18, Genesis Energy gained 2.6 per cent to $2.36, and Port of Tauranga advanced 1.8 per cent to $5.
Dairy stocks gained, with Synlait Milk up 1.6 per cent to $10.21 and A2 Milk Co rising 1.4 per cent to $12.72. Fonterra Shareholders' Fund rose 0.2 per cent to $5.76
The worst performer was Gentrack Group, coming off yesterday's record high and down 2.7 per cent to $7.20.
"If you look at volumes yesterday, it was very much just machines going off. I wouldn't read anything into that," Price said. "We've had a few people away at the Macquarie conference. The stocks have been running on very little in the way of volume."
SkyCity Entertainment Group dropped 1 per cent to $3.99, Infratil fell 0.9 per cent to $3.155, and Arvida Group declined 0.8 per cent to $1.19.
Vector was unchanged at $3.21. The Auckland electricity and gas distributor has asked the Auckland High Court for an injunction against media organisation Stuff over Vector customer data given to Stuff by a hacker, to stop Vector "failing its customers again".
Stuff says it has destroyed the data and won't give it back to Vector to avoid revealing its source, but Vector says in its last communication with Stuff, it was told Stuff would not destroy the data, and the comments to the media were "disappointing".
Separately, Fairfax Media, the Australian parent of Stuff, outlined its revenue gathering strategy as it shuts down regional newspapers. Group chief executive Greg Hywood said its audience was being monetised through digital ad sales, third-party syndication and standalone print products, along with its website Neighbourly, its joint venture Stuff Fibre, and "lead-generation partnerships with utilities, health insurance and financial service providers."
Fairfax's ASX-listed shares gained 1.3 per cent to 76 Australian cents.
