New Zealand shares gained, with turnover peaking for the week as investors tidied their portfolios. Sky Network Television and Scales Corp gained while Meridian Energy fell.

The S&P/NZX 50 Index rose 17.64 points, or 0.2 per cent, to 7.361.09. Within the index, 23 stocks gained, 21 fell and six were unchanged. Turnover was $187.3 million.

"People are tidying up some things, there's quarter-end, month-end stuff, and there appears to be fairly significant intraday volatility in some stocks.

"There's quite decent volume gone through and it appears to be offshore driven," said Craig Stent, director and research analyst at Harbour Asset Management.


Sky led the index, up 3.6 per cent to $4.92, while Scales Corp gained 2.9 per cent to $3.23 and Metlifecare advanced 2.1 per cent to $6.25.

Air New Zealand was unchanged at $1.86. The airline is considering a $75 million retail bond offer next month to partially repay the upcoming maturity of an existing $150 million note, with full details available next week.

Some 9.2 million shares in the company were traded, worth $23.6 million. The stock fell as low as $2.56 and bounced as high as $2.63 in the day's trading.

In the past month or so the market theme has been for yield or yield-related stocks such as the gentailers and Spark to come under selling pressure, Stent said.

"That reflects that interest rate rises may be just around the corner from the Fed," he said. Outside the main index, Intueri Education Group dropped 5 per cent to 11.4 cents.
