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 in the 1860s. Henry Walton and William Grahame took a 99 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 1882, replaced the tramway. Output of the mine was by 1885.
