Maori Party MP Te Ururoa Flavell's being urged to learn more about suicide before he "opens his mouth."
The MP has suggested suicide victims should be buried at the cemetery gates and condemned rather than having their lives celebrated.
But suicide prevention groups and other MPs are furious including the Progressive Party's Jim Anderton, whose daughter took her own life.
Mr Flavell says he did not mean to upset people, but simply wanted to raise awareness of the problem.
