Opanuku at Vintage

The Opanuku Stream flow site is located in Vintage Reserve, Henderson.


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

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