"This story was already flagged in the overseas trade figures," said Michael Gordon, senior economist at Westpac Bank. "Dairy production had recovered to pre-drought levels by the September quarter, but wasn't shipped overseas until the December quarter."
He said the manufacturing figures were consistent with Westpac's forecast for gross domestic product to have risen 0.9 per cent in the fourth quarter.
The value of manufacturing sales rose 6.3 per cent in the fourth quarter, or 1.1 per cent once dairy and meat were stripped out. The value of dairy and meat sales rose 18 per cent.
Among other contributors to the rise in volumes, transport equipment and machinery and equipment manufacturing rose 5.9 per cent. Fruit, oil, cereal and other food manufacturing rose 5 per cent.
These were also the biggest contributors to the gain in the value of sales after dairy and meat. Transport equipment and machinery and equipment manufacturing rose 4.5 per cent by value and fruit, oil, cereal and other food manufacturing rose 5 per cent.
