Mangemangeroa Creek is a tidal estuary and stream in the Auckland Region of New Zealand's North Island.

[1] The plant was traditionally used by Ngāi Tai to construct fishing nets, ropes, and as a part of burial practices, and is now rare in the area.

Closer to the creek are areas forested with native trees, including tōtara, nīkau, karaka and pūriri.

Mangemangeroa was one of the locations visited by the Tainui migratory waka, as the crew explored the eastern bays of the Auckland Region.

[12] In August 1994, the Manukau City Council purchased land that bordered the creek, at the request of Forest & Bird.
