17 While this section undoubtedly provides a wide discretion to council in granting an approval under this section, any discretion must be limited by the overall constraints imposed by the Act itself. Section 3 provides the objects for the Act. These are:
(a) to set out the rights of members of the public to pass along public roads, and
(b) to set out the rights of persons who own land adjoining a public road to have access to the public road, and
(c) to establish the procedures for the opening and closing of a public road, and
(d) to provide for the classification of roads, and
(e) to provide for the declaration of the RTA and other public authorities as roads authorities for both classified and unclassified roads, and
(f) to confer certain functions (in particular, the function of carrying out road work) on the RTA and on other roads authorities, and
(g) to provide for the distribution of the functions conferred by this Act between the RTA and other roads authorities, and
(h) to regulate the carrying out of various activities on public roads.
18 There is no provision in the Roads Act 1993 that would suggest that the powers extend beyond the matters identified in s 3, and particularly to matters relating to the reconsideration of planning matters normally exclusively dealt with by s 79C of the EPA Act. I agree with the submission of Mr Wright that the only practical explanation for the requirement for approval under s 125, in this case, is to give effect to condition 50. The approach is similar to the way a Construction Certificate gives effect to conditions of a development consent. I do not accept that there is any basis to conclude that s 125 is to provide a further opportunity to reconsider issues that were previously considered and determined as part of the merit assessment of the development application.
