Ngāpuhi chief Hongi Hika's campaign against Ngāti Whātua ends with the battle Te Ika a Ranganui on the Kaiwaka River (approximately 105 km north of modern downtown Auckland). Hongi's eldest son is killed in the battle. Most of the Ngāti Whatua survivors, heavily defeated, flee south, leaving Tāmaki-makau-rau (Auckland) almost deserted until the arrival of GovernorWilliam Hobson in 1840. Hongi later pursues the Ngāti Whatua survivors into the Waikato.[2][3][4]
