Hon DAVID PARKER (Minister for the Environment): I'm happy to elucidate a little bit more. In respect of Māori wards, if Māori wards are to be in place in a date and time for the local government elections next year, that creates effectively a cascade of dates backwards, and in respect of the climate change auction prices, that's necessary so that by the time the first auction under the revised emissions trading rules takes place, there is a reserve price able to be put in place. At the moment, the legislation doesn't allow an auction reserve and this legislation is necessary to put that in place before the first auction.
