Whau Valley is a suburb of Whangārei, in Northland Region, New Zealand.

The MacDonald family was part of the group of people from Nova Scotia who settled in the Whangārei area.

[8] 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,[9] replaced the tramway.

The results were 74.9% European (Pākehā); 28.4% Māori; 4.3% Pasifika; 8.3% Asian; 1.3% Middle Eastern, Latin American and African New Zealanders (MELAA); and 2.7% other, which includes people giving their ethnicity as "New Zealander".

St Francis Xavier and Whangarei Adventist schools are state integrated.
