Ka haere tāua.
We (2 people, inclusive of listener) will go.
Scenario: Tama and Mere are going. Tama goes to tell Mere that they will go. He says "E Mere, Ka haere tāua" which means "Mere, we (2 incl) will go". Mere knows that it is Tama and her going, as Tama used the inclusive pronoun for 2 people tāua.
