We take raw water from a number of sources, and our two main storage reservoirs at Whau Valley and Wilsons Dam ensure continuous supply during even prolonged dry spells.

Two other dams, the Gomez Dam at Hikurangi and Takahiwai Dam at Ruakaka, are not currently in use but are available in emergencies.

Whau Valley Dam

Whau Valley Dam holds 1,871,286 m3 of water and supplies Whangarei City and its surrounds.

The catchment area also has recreational value and management of it is included in our reserve management plan for Pukenui Forest.

  • Boating and swimming are not allowed at this dam.
  • Dogs must be kept on a leash around the Whau Valley Dam as young kiwi have been released into the area.

Wilsons Dam

Wilsons Dam holds 2,491,730 m3 of water and supplies the Bream Bay area. 

  • Boating and swimming are not allowed at this dam.
