Hon DAVID PARKER (Minister for the Environment): The aluminium dross has been stored in the Mataura warehouse since about 2011. In July 2019, a contract was entered into between central government, local government, the landlord, and the smelter for its removal. Since then, 2,065 tonnes have been removed and under that contract removal is due to be complete by August 2022. In addition, there are attempts to have the dross moved more quickly. That matter is currently before the Environment Court in a case primarily between the Environmental Defence Society and New Zealand's Aluminium Smelter Ltd, although the Crown is a party. Environment Court Judge Newhook has been attempting to mediate a solution. For the benefit of the member, I draw his attention to the most recent minute of Judge Newhook, which was dated 12 November and said—I quote, "The aim remains to [remove] it by Christmas (possibly weather-dependent), subject to the remaining issues being finalised". I can advise the member that I am under some restrictions as to what I can say, but it's obvious that those issues have not yet been finalised and that it's unlikely that the remaining dross will be removed by Christmas.
