I was fortunate enough to be the chair of the select committee which actually considered this bill, the Transport and Infrastructure Committee, and we had a number of submitters who were actually, invariably, very positive about it. There was a matter brought, particularly, that's been mentioned by Minister Parker, around what was ballast water and what was sediment. And, of course, this was important to be worked out, because, without going into too much detail, these ships will be carrying things called scrubbers, which they will actually put the emissions through. As a result, there will be sediment, there will be materials that do need to be dealt with when they come into New Zealand ports. That was why we did require to make that change that has been previously mentioned—because each of the ports will be required to actually have the ability to deal with this material.
