New Zealand's economy grew at its fastest pace in almost two years in the September quarter as manufacturing and retail spending rose during the Rugby World Cup, but markets remained wary of the impact from the European debt crisis and continued to expect low interest rates for longer. 

Gross domestic product rose a seasonally adjusted 0.8 percent in the July-September quarter from the second quarter, compared with a 0.6 percent forecast in a Reuters poll and the Reserve Bank of New Zealand. 

The data failed to impress markets as recent historical numbers were revised down by around 0.5 percentage points, pulling down the annual economic performance.
