Through engagements with transport regulators, the Ministry of Transport has realised that these exemption powers lack some necessary features and do not reflect modern best practice. In particular, the current provisions do not give regulators clear powers to grant class exemptions where a category or thing or person is defined. Changes in the bill specifically provide for class exemptions and will make sure that these are treated in the same way as secondary legislation—since they are, effectively, changing a rule for a group or category.
