I was actually quite struck by reading in the legislative statement the extent to which we import timber, as well as the export. Again, Mr Muller referred to that. So the balance of trade calculation is interesting. As an export earner, some $6.3 billion worth in the year ending June of last year, and in the equivalent period, $2.35 billion going the other way. So we do win overall on that equation, but it's not insignificant that we have timber from other nations coming in. And so, of course, we want to assure ourselves as to the legal provenance of that. Of course, New Zealand has a reputation already as a high-quality exporter of timber products. We do trade on our reputation, quite literally, in the sense that we want those international markets not only to consider us "100% Pure", as the marketing campaign goes, in an environmental sense, but also in assuring the purity of our products, in the sense that it is legally pure, almost morally pure, if we're talking about, again, the environmental aims that go alongside the commercial imperatives to protect the trade.
