Activity in the manufacturing sector fell June after picking up sharply in May.
The BNZ Business New Zealand Performance of Manufacturing Index fell 5.6 points to 50.2 - the lowest June reading since 2009.
A reading over 50 indicates the sector is expanding.
New orders, production and finished stocks expanded, but employment and deliveries fell.
BNZ Economist Doug Steel says manufacturing activity has been choppy for some months, and that's likely to continue.
