New Zealand: Winstone Wallboards says that it successfully started a test run on the new production line at its new Tauriko gypsum wallboard plant in mid-May 2023. In a statement general manager David Thomas said “The team successfully put ‘slurry on paper’ and ran board down the line and, beyond our initial plan, through the dryer.” He added the company was confident that it would be producing wallboard in the second half of 2023.
