The consultation occurred on whether we should sign this, and obviously, in doing so, we just have to make sure that there are all considerations, and the two global problems relating to shipping emissions are, of course, impacts on human health and environments in port communities from maritime pollution. While I've mentioned Wellington Harbour, you go to somewhere like Picton, which, again, is in a narrow valley. That's now one of New Zealand's busiest ports. In fact, Picton's a bit unique, because most New Zealand ships—certainly coastal ships—haven't complied with this, whereas most international ships coming here now have. Most of the container boats—certainly most of the cruise liners—that have come here do actually comply. So you get a port like Picton, where, obviously, while being busy, most of those visits are from ferries going back and forth, and those ferries don't actually comply, so you can imagine what the impact on a place like Picton might be.
