Mr Cameron said the point that things are different in different parts of the country, and that's quite so. The problems in the Kaipara are different. But central government and local government are, between themselves, with some help from landowners, spending over the next 10 years $200 million to stop the build-up of sediments in the Kaipara, which is the nursery of snapper for the West Coast of the North Island. It's a juvenile white pointer - raising area, and there are recent mudbanks in the Kaipara that are 2 metres deep—2-metre deep recent mudbanks—and I've seen them. It's terribly sad. Every tide, there's another film of additional sediment. Some of it's coming from inappropriate management of fill coming from subdivisions into the north of Auckland. Some of it's coming from agricultural sectors, and that needs to be improved too.
