Hon MICHAEL WOOD (Minister of Transport): It is a real focus of our Government, particularly in light of the independent climate commission's recommendations that we reduce our emissions and decarbonise the transport system. The rebalancing that we engaged in around the New Zealand Upgrade Programme earlier this year was significant in this regard, and the overall impact of the New Zealand Upgrade Programme now is actually to reduce emissions on the whole. So I'm really pleased with the progress that we've made there. But we know that we need to continue carefully considering the projects that we invest in.
