He built three great wharenui (meeting houses) for different sections of Ngāti Tūwharetoa. When the Tūwharetoa chieftain Tutakaroa attacked Te Rangi-tua-mātotoru’s allies in Ngāti Tahu, he summoned allies from Te Arawa to attack Tutakaroa at Whakaohokau, but had second thoughts about the venture and arranged a peace before Te Arawa could wreak havoc.
