Holcim New Zealand Ltd has gained interim resource consent to operate a new cement plant at Weston, near Oamaru.  
 
Holcim has until December 19 to respond to a range of conditions specified by the commissioners, covering hours of operation, noise, air quality, and traffic management. ``Obviously we are delighted that the commissioners have issued an interim decision so promptly,’’  Holcim capital projects manager, Ken Cowie, said.  
 
He said the ultimate go-ahead rested with its Swiss parent company,  Holcim Ltd, which will weigh up whether in the long-term it should build a new plant at Oamaru or one near Westport.  
 
Its current Westport plant is running to full capacity, and importing cement to supplement demand.
