So what ACT would advocate for is better education and, for the agencies involved in certification, to identify where those gaps are in education and training, and to propose better vocational education qualifications if that's necessary, and also a process to review the practice of these designers and fabricators so that they can receive the benefit of continuing professional development as they go about their vitally important work. And it is vitally important work, because not only do we need this equipment to be safe, but we also need more trucks on the road to cart more quarry products and aggregates from those quarries to cement plants, and then the concrete to the house building sites and to the roads and even to the railways that our colleagues in the Green Party and previous and current Labour Ministers are so fond of—those railways, which will consume hundreds of thousands, if not millions of tonnes of concrete and other products; this year, expected to run to 4 million cubic metres or 10 million tonnes of concrete coming from batching plants in trucks on the roads. And you can't make concrete without getting the rock from the quarry to the batching plant and the cement from the cement kiln to the batching plant.
