What is the formal process for a mihi whakatau?

My first experience of a Mihi Whakatau was when I was welcomed into Merrin School where I now work. 

A mihi is a formal way of respecting people by acknowledging their mana and tapu (dignity and sacredness). It is a sign of hospitality and respect to mihi on important occasions.

Being such a new experience , I wanted to find out more so I felt more comfortable in the process and was ensuring I was respectful as we all went through such a special time together.
