State Highway 15A (SH 15A) is a New Zealand state highway in the Northland region of the North Island. It is 8.5km long and links SH 1 with the Marsden Point Oil Refinery and Northport. SH 15A is a peculiarity since there is currently no corresponding SH 15. This is because SH 15, which used to connect SH 1 with the former site of Port Whangarei, had its highway designation revoked in December 2003. SH 15A was created six months later, in June 2004, to provide a highway connection to the new site of the port at Marsden Point.

Route

SH 15A commences near the town of Ruakaka, 26km south of Whangarei, at a roundabout with SH 1. It travels northwest along a road named Port Marsden Highway for 8.5km, terminating at the entrances of Northport and Marsden Point Oil Refinery. The first 3km of the highway runs along the route formerly taken by the southern end of One Tree Point Road, which was significantly realigned as part of its upgrade to highway status. The next 3km of the highway uses a section of road which was newly built as part of the creation of the highway, whilst the final 2.5km uses an existing road which was formerly the northern end of Marsden Point Road.
