Hon DAVID PARKER: Far too long. Dross has been stored at the old Mataura mill since early 2010, or thereabouts. The problems were exacerbated when the contractor hired by the Tīwai smelter to dispose of it went into receivership. This left the dross stuck in Mataura, with everyone denying ownership and responsibility—and, understandably, worrying local residents. Since 2017, we have worked to achieve a solution. We're glad it's been resolved. The efforts of many people need to be acknowledged. I'd like to particularly acknowledge the local residents; the Gore District Council; the local MPs, Dr Craig and Mark Patterson when he was here; Environment Southland; the Environmental Defence Society; Ngāi Tahu; Inalco Processing, who've been helpful; as well as, in the end, the smelter, for doing the right thing.
