Several of the major banks expect a significant bounce back in GDP for Q3 when Stats NZ releases its economic figures later this morning. 

Westpac and ANZ both predict a gain of about one percent, putting that down to a jump in activity across the board. 

ANZ Chief Economist Sharon Zollner told Heather du Plessis Allan while she's nervous some of that could turn up in the revised numbers down the track, it's looking positive. 

She says some of the corners should be knocked off the volatility in the economy and the overall level of GDP will be revised up.
