Sky Network Television was the worst performer on the local index, down 5.8 per cent, or 13 cents, to $2.11. It gave up rights to a 7.5 cent interim dividend.
"Certainly the bottom end of the market has been hit by [stocks giving up dividend rights], both Sky TV and NZ Refining went ex-div, although Sky has given up a bit more than the dividend," Easton said. "Obviously people have been holding on for the dividend for some reason, and now they're just giving up. It has been a long slide for them."
New Zealand Refining Co fell 4.5 per cent, or 11 cents, to $2.35. It shed a 12 cent final dividend.
Other benchmark index stocks to give up dividends today were Mercury New Zealand, which dropped 4.5 cents to $3.225, compared to its 6 cents per share interim dividend; Investore Property, which dropped 3 cents to $1.38 while shedding a 1.86 cent dividend; Vital Healthcare, which dropped 1 cent to $2.12, compared to its 2.125 cent dividend; and Metlifecare, which shed 1 cent to $5.84 while dropping a 3.25 cent dividend.
Synlait Milk was the best performer, up 2.3 percent to $8.08. Heartland Bank rose 1.7 percent to $1.80 and Z Energy gained 1.2 percent to $6.95.
Outside the benchmark index, Trilogy International gained 2.2 per cent to $2.83. It is set to de-list from NZX with shareholders backing a $211m takeover from China's Citic Capital Partners at today's special meeting. The deal will see the Chinese investment firm pay $2.90 a share to take over the listed skincare products and scented candle maker.
"It's now just awaiting Overseas Investment Office approval, which the company has asked for by the end of March, so that could well be another company off our exchange in the very near future," Easton said.
