Manufacturing sales volumes rose slightly in the June 2012 quarter, latest figures from Statistics New Zealand show.
After adjusting for seasonal effects, the volume of all manufacturing sales rose 0.3 per cent compared with the first three months of the year.
However the total value of manufacturing fell 1.1 per cent in the quarter.
''This quarter's increase was the result of an almost even split of seven industries rising and six industries falling,'' industry and labour statistics manager Blair Cardno said.
The main movers in the quarter were: meat and dairy product manufacturing, up 1.8 per cent; transport equipment and machinery and equipment manufacturing, up 4.7 per cent; and petroleum and coal product manufacturing, down 9.0 per cent.
Excluding meat and dairy product manufacturing, sales values were relatively unchanged.
Values in the meat and dairy category fell 3.1 per cent in the three-month period.
The trend for the manufacturing sales volume, which gives a longer-term picture of movements, indicates manufacturing volumes have been fluctuating around the same level for three-and-a-half years, Statistics said.
