Employment also dipped, dropping 1.4 points to 51.3.
Last week's June household labour force survey from Statistics New Zealand showed employment in the manufacturing sector flat on the March quarter but up 1.6 per cent or 3900 people on a year ago.
BNZ economist Stephen Toplis said manufacturing had probably passed its peak in terms of growth, consistent with the broader economy which was peaking about now. But the levels of activity were still robust, he said, as much of the manufacturing sector provided inputs to the buoyant construction sector.
The stronger-than-expected June quarter retail sales figures released yesterday also explained, in part, why the manufacturing PMI remained well in expansion territory as the sector benefited from strong domestic spending growth and soaring building activity, Toplis said.
NZIER's recent quarterly survey of business opinion (QSBO) recorded positive expectations among manufacturers for both domestic and export sales.
"Close to average export sales expectations is a commendable result given that the New Zealand dollar remains a long way above average. Export expectations may well lift as the dollar has eased back since the last QSBO and more so if the currency falls further as we think it will."
