The Akatarawa River is in the lower North Island of New Zealand.
It is a short river, flowing south for 20 kilometres (12 mi) through small rocky gorges and the Akatarawa Valley before joining the Hutt River at Birchville, a suburb in the northern end of Upper Hutt. Its eventual outflow is into Wellington Harbour, then into Cook Strait.
