Also in 1821, Ngāpuhi war leader Hongi Hika acquired several hundred muskets in Sydney and this changed the balance of power between "iwi". In September 1821 Hongi Hika led an expedition that attacked and took the two Ngāti Pāoa "pā" of Mauinaina and Mokoia at present-day Panmure. Hongi Hika continued with attacks at present-day Thames and in the Waikato. Te Kawau's Amiowhenua expedition ended when his Ngāti Whātua forces, uniting with the Taranaki they were embattled with, jointly defended Tainui's Matakitaki "pā" from Hongi Hika's forces. In 1825 Hongi Hika was victorious over Ngāti Whātua in the battle of Te Ika a Ranganui near Kaiwaka, and pursued survivors into the Waikato. From this time the Auckland area was all but deserted.
