So what the submitters proposed and what we haven't heard yet from the Minister is whether a professional practice, essentially like a mechanical engineering or a civil engineering discipline, could be created around the certification process. Because if there are going to be thousands of trucks and buses and trailers and log trucks and bulk trucks on our roads, and those being manufactured new and being adapted and modified every year, then we would want to know that the people certifying them aren't just people who've come from the factory floor or from the shop but they are actually people who understand engineering design processes, safety in design—all of those things that we've learnt how important they are through the Christchurch earthquakes, Pike River, and other disasters which have shone a very bright light on the role of professional engineers' training and continuing professional development, as well as the regulatory auditing function.
