New Zealand: Winstone Wallboards says it is moving away from its gypsum wallboard allocation model as a market shortage has eased. The company’s general manger David Thomas said that its GIB Weatherline and GIB Barrierline products were no longer on allocation. It now intends to take all of its wallboard products out of allocation over the next few months. The subsidiary of Fletcher Building introduced an allocation model of wallboard supply in the summer of 2022 to cope with a national shortage.
