The Whangae River is a short river of the Northland Region of New Zealand's North Island. It flows generally northeast to reach a southwestern arm of the Bay of Islands. The estuary is about and the river about long. Like much of the coast north of WhangÃÂrei, the valley is formed of Waipapa greywacke.
The Whangae River Estuary is designated as an area of Outstanding Natural Character, due to its railway causeway (now followed by the Pou Herenga Tai â Twin Coast Cycle Trail) and its tall mangroves (mÃÂnawa), which give way up river to saltmarsh. Bush covers much of the valley, mainly taraire-pà «riri forest with emergent rimu, rewarewa and occasional tà Âtara, pukatea, kahikatea and kauri. More tà Âwai grow towards Opua. There are also areas of manuka, kÃÂnuka, tanekaha, kohuhu. five finger (puahou), mamaku, patÃÂ, hangehange, cabbage tree (të), cutty grass and raupà Â, with Northland green gecko (kawariki), tomtit (miromiro), brown kiwi, weka, kererà « and kà ÂtÃÂtÃÂ.
From 14 August 1931 to 1 September 1963 there was a Whangae Bridge flag railway station.
