Origin: Maori (Māori) Mythology, Whanganui, New Zealand
Tutaeporoporo was a water-serpent that inhabited the river of Whanganui. The creature was favored by the chief Tuariki, but, for some reason, turned deadly. The creature began eating people by the boat loads. 
It was then that Aokehu appeared to save all those who lived near Whanganui. He managed to float down the river in a hollow log toward the dragon's lair. The creature came to swallow him. 
However, Aokehu had a different plan. He killed the creature from withing utilizing sharks' teeth. The creature drifted ashore and Aokehu was freed. Today, Tutaeporoporo is depicted on Wanganui City's coat of arms. 
Following the common description of a Taniwha, Tutaeporoporo was a huge lizard that dwelled within a river.
