New orders recorded the highest reading in the latest survey at a seasonally adjusted 62, compared with 60.7 in October and 51.7 in November last year. Production at 59.4 and deliveries of raw materials at 56.7 both increased to their highest level of activity since July. Employment increased to 53.3 while finished stocks dropped to 50.2 although remained in expansion.
Key sectors such as metal product manufacturing were showing "stellar levels" of activity, helped by a boom in construction, BusinessNZ executive director for manufacturing Catherine Beard said in the statement.
For the first time since November 2010, all areas of the country displayed post-60 levels of expansion.
The robustness of the latest survey indicated activity had broadened outside of Canterbury, where activity is higher as a result of rebuilding following a series of earthquakes, Ebert said.
The Northern region recorded its highest level of activity since November 2009 while the Central region posted its highest level of activity since November 2002.The Canterbury/Westland region continued its onwards momentum while the Otago-Southland region showed a similar result to the same time last year.
Survey respondents noted a stronger pre-Christmas rush compared with previous years, BusinessNZ's Beard said.
