New Zealand shares rose, joining a regional rally, as investors predict whether an upcoming MSCI index review will spur major activity next week. Fletcher Building, which could exit the index, gains, while new addition a2 Milk Co fell.
The S&P/NZX 50 index increased 6.65 points, or 0.1 per cent, to 8,594.59. Within the index, 29 stocks gained, 12 fell and nine were unchanged. Turnover was $132 million.
Investors are waiting to see the outcome of upcoming MSCI index changes after the rapid ascent of a2 Milk to claim the title as New Zealand's biggest listed company and the decline of long-standing bluechip stock Fletcher Building.
Brokers anticipate next week's reweighting will lead to a busier day than the previous review when about $1.1 billion of Contact Energy and Fisher & Paykel Healthcare shares changed hands. A2fell 3.2 per cent to $12.75, the day's biggest decline, while Fletcher led the bourse higher, up 3.7 per cent to $6.53.

"If a2 is included which is what most people predict, then we're talking probably the largest daily traded volume that's going to occur at the end of May than we've ever seen before," said Rickey Ward, NZ equity manager at JBWere in Auckland. "It'll be a day of significant volume if a2 goes in."
