Our economy's been shrinking much faster than economists thought. 

Latest data just out from Stats NZ shows GDP fell 0.9% in the three months to June.

Infometrics Chief Forecaster Gareth Kiernan told Kerre Woodham it's far worse than any economists were expecting. 

He says this number is completely "off the charts", as far as they're concerned.
