There was a major review of the NZTA, which concluded that there were significant issues because of the NZTA's lack of a strong regulatory role and the lack of a single regulatory voice in the agency. And if I could just read from the regulatory impact statement, that review—which Martin Jenkins conducted, and I quote—"concluded that since the NZTA's establishment, significant deficiencies in its regulatory capability have developed over time, resulting in regulatory failure. The absence of a single and clear point of accountability for regulatory decision-making in the NZTA (contrary to many other regulatory agencies), and lack of established principles of good governance, have been significant contributors to the regulatory failure." That is what we inherited from the last National Government. This bill is part of the fix to that, because this Government wants to ensure that people are safe on our roads. That means ensuring that those organisations providing warrants of fitness do so properly. It means ensuring that the police and others have the powers to detain vehicles after crashes to ensure that the causes of those crashes are properly identified, and this bill provides a power there.
