We've also required farms over a certain size to have a farm plan, or an environmental component of a farm plan, which enables a farm by farm assessment of what are the critical source areas for erosion, for example. Why is that a problem? Well, we know that in some areas like the Kaipara, we've got recent mudbanks that are 2 metres deep. This is the largest harbour in New Zealand and it's where the majority of snapper on the West Coast of New Zealand spawn, and yet we've got such high sediment loads coming into that estuary that we literally have mudbanks of recent origin that are 2 metres deep. We have contributed at central government level $100 million to a restoration package. That money is being matched by local government and farmers in order to bring forward improvements there.
