One of them that came to select committee and really did go into some detail was the New Zealand refinery up north at Marsden Point. And therein lies a real issue, because they told us that they had a special agreement that had been entered into in good faith years and years ago, at the time when the refinery was set up, going back as far as the mid-1960s, to a period of time before the refinery was set up, when actually we imported refined fuels into New Zealand in a finished state. I don't think we would want to, as a country, go back to that. So there's a case in point where the refinery company makes a good, solid contribution in terms of the day-to-day lives that we have—and, yes, over a period of time, one would expect that the reliance that we have as a nation on fossil fuels to provide fuels for transport, for light and heavy vehicles, will diminish. That's fine and dandy. But the Minister, in his answer to my colleague Erica Stanford's question, was quick to point out that the component that was the free allocation cost, if you like, to that business, relative to revenue, was very tiny. But, as a former boss of mine used to often tell me, a sale isn't profit. And, what's more, actually it's the margin; it's the proportion of the impact on the profit and the ability for that entity to trade profitably on an ongoing basis that's, frankly, more important than the revenue number.
