These days, of course, we don't rely on waka, we don't rely on sailing vessels, and we don't rely on steam; we rely very heavily in terms of shipping on, usually, dirty diesel freight ships—large dirty diesel freight ships—and much of the fuel that they are burning is full of toxins. It's bad for the environment. It has all kinds of nasty levels of sulphur, nitrous oxide, and a whole range of other substances that would be neither good for our marine environment, our atmospheric environment, nor, indeed, for human living conditions. So it's appropriate that after what probably is too long a period, New Zealand is going to finally get around to ratifying and taking our responsibilities seriously under the MARPOL Annex VI agreements and conventions that will prevent pollution from international shipping. So I think this is a good move, and I'm delighted on behalf of the National Party and my colleagues to support this legislation.
