The Arnst River in New Zealand is a tributary of the Travers River, which itself flows into Lake Rotoiti, in Nelson Lakes National Park. [1] [2]
The park is at the northern end of the South Island of New Zealand. [3] The Arnst River is named after the champion rower Jacob Diedrich Arnst, known as Richard Arnst or Dick Arnst. [2]
