1. (noun) speech of greeting, official welcome speech - speech acknowledging those present at a gathering. For some tribes a pōhiri, or pōwhiri, is used for the ritual of encounter on a marae only. In other situations where formal speeches in Māori are made that are not on a marae or in the wharenui (meeting house) the term mihi whakatau is used for a speech, or speeches, of welcome in Māori.
