# Whau Valley

Whau Valley is a suburb of Whangārei, in Northland Region, New Zealand. State Highway 1 runs through it. The valley was named for the whau trees which grew there in the 1850s.
At the end of the 4 km long Whau Valley Road is the principal water reservoir for Whangārei City, created by the Whau Valley Earth Dam. The reservoir is stocked with rainbow and brown trout.

## History

Some of the early settlers in what was then called Whauwhau Valley were William Hawken and his family, who arrived in 1859, and John MacDonald and his family, in 1860. The MacDonald family was part of the group of people from Nova Scotia who settled in the Whangārei area.
Coal was discovered in the Whauwhau Valley on 24 August 1864. Henry Walton and William Grahame took a 99-year lease on the land and developed a mine. A wooden tramway was built from the mine to the Hātea River so coal wagons could be pulled by horses to be loaded onto ships. The railway line between Kamo and Whangārei, opened in March 1881, replaced the tramway. Output of the mine was 45,359 long tons (46,087 t) by 1885.
