The source of the Waitara River lies in the very steep hill country to the east of Mount Taranaki/Egmont, near Tahora. After proceeding in a southwesterly direction toward Central Taranaki, the river abruptly turns to flow in a northwesterly direction to the Tasman Sea: meeting it at the coastal town of Waitara.[1]
The river once had a dock in Waitara, where export meat from the town's Thos. Borthwick & Sons freezing-works was loaded onto ships. However, this trade was subsequently conducted from New Plymouth's Port Taranaki until the works closed in 1995.
The Waitara is the first mud-bottomed river to the north of Cape Egmont. It is prone to flooding, and there are stop banks (levees) to the west of the river (upstream from the bridge) and on both sides downstream.
The historic Bertrand Road suspension bridge, (one of only a few such road bridges in New Zealand) is several kilometres from State Highway 3 (just up from the town).
