KEY POINTS:
The New Zealand share market plunged 2.3 per cent today as offshore markets weakened and as gains on Friday by major stocks reversed.
"Asian markets started the week in a weak fashion," said Nigel Scott, retail adviser at ABN Amro Craigs.
Many Asian markets were down 2 per cent and the Australian market was down about 1.6 per cent during the New Zealand market's session.
The benchmark NZSX-50 index closed down 84.172 points at 3540.055, reversing all of Friday's 61.1 point rise.
Volume was $232.9 million. Falls outnumbered rises by 65 to 37 among the 139 stocks traded.
Mr Scott said volume was inflated by the reporting of trades from Friday in pre-market crossings.
"There were some MSCI index adjustments on which we saw some pretty strong price appreciation in major stocks on Friday," he said.
The global MSCI stock indices guide institutional trading so weighting changes trigger buying and selling by institutions.
He said some buyers in the larger stocks held back ahead of the reweighting and they re-emerged on Friday.
"Today, the market really reacted to some profit-taking on light volume in some of those stocks," he said.
Telecom fell 20c to 382 after gaining 6c on Friday. Fletcher Building fell 30c to 770 after jumping 22c on Friday.
