The Green party is to ask Parliament to re-assert its position on religious tolerance.
The move comes in the wake of controversial comments made by NZ First MP Richard Prosser suggesting Muslim men should be barred from flights by Western airlines.
All MPs are required to support the notice in motion - and if even one objects it will fail.
The motion will re-iterate that all New Zealanders, regardless of faith or ethnicity should be treated equally before the law, and their rights and dignity upheld.
A spokesman for the Greens said it was important Parliament sent a message to New Zealand's Muslim communities.
And he said it was an attempt to mitigate some of the economic damage Prosser had done.
The Greens have so far received "good support" for the motion, he added.
