we (3 or more people) inclusive of listener

Ka haere tātou.
We (3 people, inclusive of listener) will go.

Scenario:  Tama, Mere AND Whaea Mahinaarangi are going to go.  Tama goes to tell Whaea that they will all go, including Whaea.  He says "E Whaea, Ka haere tātou" which means "Whaea, we (3+ inclusive of listener) will go".  Whaea knows that she is going with Tama and Mere because Tama used the inclusive pronoun for 3 or more people tātou.
