State Highway 45 (SH 45) is a New Zealand state highway which has the moniker of the Surf Highway due to the number of prominent surfing breaks that are accessible from it.
It is two-line single carriageway for most of its length, with at-grade intersections and property access' in both urban and rural areas.
Route
SH 45 leaves at the corner of Leach and Eliot streets north-east of the New Plymouth CBD. It then continues west along the New Plymouth one-way network (westbound Leach and Vivian streets, eastbound Powderham and Courtenay streets) then onto Devon St West and South Road exiting New Plymouth via the south-western suburbs. It then heads south-west along the Taranaki coastal plain passing through Ōakura and Ōkato. At Cape Egmont it turns south-east following the coast passing the Oaonui production station and through Ōpunake and Manaia before terminating at the crossroad intersection of Waihi, Denby and South Roads in Hāwera, where it again meets SH 3.
