SH 67 starts at SH 6 and proceeds in a northerly direction until the intersection with SH 67A. There the road turns right and crosses the
Buller River to enter the township of
Westport. Once in the CBD, the highway turns right and proceeds in an easterly direction until it crosses the
Orowaiti River. The road passes through alternating areas of farmland and temperate rainforest vegetation as it passes the settlements of
Waimangaroa (turn right here for
Denniston), Birchfield,
Granity (turn right here for
Millerton,
Stockton and
Stockton Mine),
Ngakawau and
Hector. Before Hector the road crosses the
Ngākawau River. Beyond Hector, the road acts as a frontier between the coastline and the adjoining hills until it reaches
Waimarie and
Summerlea, where it swings inland towards
Mokihinui and its turn-off to
Seddonville. The State Highway ends at the bridge across the
Mōkihinui River, but the road continues to
Karamea as Regional Route 67 using white shields (). ==Spur sections==
