The Cyclopedia of New Zealand [Auckland Provincial District]
Mongonui (or Mangonui), in the county of that name, is 134 miles from Auckland. It has a fairly good harbour, which was visited by Captain Cook. The country is poor in character as a rule, though there are the rich valleys of Oruru and Victoria. Mongonui possesses a good hotel, a church and a public school, and has weekly communication with Auckland. It also has a telegraph and money order office, and a post office savings bank.
