The bill as it's been proposed is really around enabling the Minister to make marine protection rules around Annex VI, around air pollutant substances, which are things like nitrous oxides in sulphur, oxides in particulate matter. That's important because it makes our harbours and our communities around those harbours much safer and, obviously, has some public health benefits. It enables the director of Maritime New Zealand to make interventions, to do audits, to check that, actually, ships are complying with Annex VI, and it has a number of obligations on them, which is fantastic.
