Summary of report findings
Development of the Campbells Bay Stream catchment began in earnest after the First World War and included the clearance of 100 acres of kauri forest and bush in 1918 to establish a golf course. The opening of the Auckland Harbour Bridge in 1959 also gave impetus to residential development within the area. The catchment is now largely fully developed. The stream consists of two distinct main channels. Although the catchment has been urbanised the stream retains significant natural character. Tributary 2 in particular has relatively good remnant native riparian vegetation.
