SkyCity Entertainment Group rose 2.4 per cent to $4.20.
"It has been quietly improving since it came out with its result back in February, It wasn't much to smile about but the stock has been quite weak," Williamson said.
Heartland Bank gained 1.9 per cent to an all-time high $1.62. It has completed $40m of capital raising after its discounted share purchase plan closed more than three times oversubscribed. The lender raised $20m selling shares to existing investors at $1.46 apiece, saying the offer would be scaled back because it received applications for $62m of shares.
"A few shareholders will be a little disappointed with the results of the capital raising as they're not getting as much so they're topping up on market to get their stakes back up," Williamson said. "It's been a pretty impressive performer."
Summerset Group was the worst performer on the index, down 3.3 per cent to $5.22, while Goodman Property Trust dropped 2.5 per cent to $1.195 and NZX fell 1.8 per cent to $1.07.
Warehouse dipped 0.4 per cent to $2.48. It will leave the NZX50 Index when it rebalances on March 20, to be replaced by Sanford.
"Obviously it's trading pretty low on a historical basis, it has been failing to meet expectations and investors will be pretty disappointed with its performance. It seems to always be undertaking restructuring but there's still a long road to go," Williamson said.
Outside the benchmark index, Energy Mad was placed in a trading halt at 2.4 cents pending an announcement. The shares have dropped 27 per cent in the past 12 months.
