"New Zealand's Performance of Manufacturing Index (PMI) bounced back very well in February," Bank of New Zealand economist Craig Ebert said in a note.
"This was driven mostly by the two components that caused all the consternation back in January, with the PMI production index increasing to 51.8 from 47.4, while the new-orders index rebounded right the way up to 61.5 from 50.1."
Across industry groups, petroleum, coal, chemical and associated product manufacturing jumped to 62.9 in February from 37.5 a month earlier, the lowest level since 2009 and when a global slump in oil prices weighed on the sector.
Food, beverage and tobacco manufacturing posted a reading of 60, while machinery and equipment was little changed at 54.8.
Metal product manufacturing improved to 53.3.
Activity across all four regions expanded in February.
The Otago-Southland region increased to 60.7, while Canterbury Westland rose 7.5 points in the month to 55.8.
The Northern region posted a reading of 54.9, while the Central region reported a reading of 55.4.
