Wharekopae River
The Wharekopae River is located in the northeast of New Zealand's North Island. A tributary of the Waikohu River, it rises on the slopes of Maungatapere, a peak at the northeastern end of the Huiarau Range, and flows east, reaching the Waikohu River at the settlement of Waikohu, west of Te Karaka.
At Rere, it cascades over the Rere Rock Slide, a smooth, natural rock formation long, and the picturesque Rere Falls.
The river's name is Māori for "house with a side door", which would have been an unusual feature of a traditional Māori dwelling.
