LAWRENCE YULE (National—Tukituki): Minister, thank you for your answers to my questions on TB. I just want to come back to them for a minute, because the scale I've mentioned is significant in Hawke's Bay. But one of the new issues that's emerged is that plantation forest owners do not pay a levy, a TB levy, and what happens in the growth of the forest is that the possums all go and live in the forest, and as soon as the harvesting operation starts, they are, obviously, disturbed and they all leave and go out into the fields. So my question, really, is: is the Ministry for Primary Industries doing any work, or is Operational Solutions for Primary Industries New Zealand doing any work, on whether in fact we need to review the structure of payments, particularly around forestry operators, and the need to poison prior to harvesting? In Hawke's Bay, as I understand it, that is one of the factors that has made the spread way worse than what was anticipated.
