The Ararimu flow site is located in farmland in the Waikoukou valley.  The Ararimu River drains into the Kaipara River.


Ararimu was initially installed as an investigative site for WaterCare as a proposed water source, however the current use is for the monitoring of run off from surrounding forestry.
