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 says 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.
