Now, it's a matter of some concern to two iwi groups within Horowhenua that there could be an exception to their area, and I understand their concern in that for far too long they've had to put up with Lake Horowhenua effectively being a dumping ground for pollutants from that catchment that they've had to put up with ruining their lake. So we're determined to improve things in Lake Horowhenua, and we are considering whether our revised proposal to have a complete exemption for ever to the nitrate toxicity level is appropriate or whether there should be some narrower form of interim exemption which none the less sustains vegetable production, which, of course, we need for human health. There aren't that many places that we can grow those leafy greens that we all need to have a healthy diet at an affordable price, particularly in winter.
