Hon DAVID PARKER (Minister for the Environment): Thank you, Madam Chair. I mean, I would say that two of the most pressing issues in Canterbury are nitrate levels in groundwater and problems which are partly nitrate-related in the Ashburton lakes area, which are at risk of tipping into a state which will see them severely degraded to the extent that they're not already. The member's quite right that the national policy statement (NPS) on freshwater management includes new attributes in respect of these issues, which have to be met by new water plans. I'm also aware that the NPS on drinking-water sources is of relevance, which is a matter which is under the control of the Hon Kiritapu Allan.
