The S&P/NZX 50 Index declined 143.87 points, or 2.5 percent, to 5607.32 today.

"It's one of those things - stocks go up in escalators and come down in elevators," said James Smalley, director at Hamilton Hindin Greene.
Xero, the cloud-based accounting software firm, led the benchmark index lower, down 8.1 percent to $13.80 while A2 Milk declined 5.5 percent to 69 cents.
Chorus shares fell 4.6 percent to $2.625 after the telecommunications network operator reported a 39 percent decline in annual profit to $91 million as the lower regulated price for its copper-based services generated weaker revenue.

Property investors and other defensive stocks fell to a lesser degree, Mr Smalley said.
