State Highway 17 was a 32 kilometre stretch of highway in the North Island of New Zealand that was revoked at the end of 2012 by NZTA. It linked State Highway 1 at Puhoi and State Highway 1 at Albany. Its main destinations were the towns of (from north to south) Waiwera, Orewa, Red Beach, Whangaparaoa, Dairy Flat and the suburb of Albany.
SH17 was part of SH1 before the extension of the Northern Motorway in the late 1990s. Between December 1999 and January 2009, SH17 ran from present-day Exit 412 at Greville Road north through Albany and Dairy Flat to the interchange of SH1, SH1A and SH17 at Silverdale (Exit 398).
When the SH1 Northern Gateway Toll Road opened on January 25, 2009 it replaced both SH1's old route and SH1A, and SH17 has extended to replace the latter two roads, although this extension has not been signposted.
State Highway 17 was revoked in October 2012 because there was no need to maintain SH1 and SH17 as close together as they were, especially as most long-distance traffic was taking the SH1 toll road. Upon revocation, the route became Urban Route 31.
SH17 began at the junction with SH1 just south of Puhoi, at Exit 388. While SH17 officially started here, it was not signposted until its original (pre-toll road) terminus at Silverdale. SH17 wound over the Johnston Hill and down into the town of Waiwera. From here it becomes the Hibiscus Coast Highway and continued along the hills, coming down into Hatfields Beach and over another hill into Orewa township.
After crossing the Orewa River SH17 arrived at Red Beach, where there are intersections at Red Beach Road and Whangaparaoa Road for Whangaparaoa and other peninsula suburbs. Just outside Silverdale is the intersection with East Coast Road, a third route into Auckland city via Urban Route 25. Almost a kilometre after this is the interchange (Exit 398) with SH1, the Northern Motorway and Northern Gateway Toll Road. From here SH17 was signposted through to the city.
SH17 continued through mostly rural countryside to Albany township, passing through Dairy Flat. Just outside Albany, the surface quality of the highway improves and Botts' dots replace painted lines on the road at the intersection with the Coatesville-Riverhead Highway. As the road enters Albany it becomes the Albany Expressway, running through the township until it meets the Albany Highway, whereupon it becomes a dual carriageway through to its terminus at Greville Road and SH1.
