History
The Valley was one of the last areas explored by Europeans in northern Marlborough. John Tinline discovered it while looking for a route to Nelson in January 1850.

The Rai Valley was densely forested in the 19th century. A township grew up at Carluke, just to the west of Rai Valley locality, around a sawmill built by William Brownlee in 1907. About 100 people worked at the mill, and a light railway connected it to a port on the Pelorus River.

Returned servicemen took up many local farms in 1919.
