If I can just take a couple of moments to speak to the referral motion and why it is that the Government is seeking from the House a shortened report-back date and the other conditions that I have just outlined on this piece of legislation. The driving reason is that we are very keen to ensure that New Zealand can accede to MARPOL Annex VI in early 2022 in line with international commitments that we have made to ensure that New Zealand can benefit from the reduced air pollution that will come from ascension to the treaty and, very importantly, to ensure that New Zealand can assume a credible role in negotiations at the international maritime organisation that will be beginning to occur from that time onwards. Our ability to be able to stand up and say that we have acceded to MARPOL Annex VI is an important part of New Zealand's ability to engage in a meaningful way in that process.
