The Oratia Stream flow site is located at Millbrook Road, Henderson. 


The Oratia Stream drains into Henderson Creek, an arm of the Waitemata Harbour. 

The Oratia Stream is very susceptible to significant flooding of the lower catchment, therefore high stage alarms are in place to notify the public of significant rising water levels.
