An online petition calling for a film on the Christchurch mosque attacks to be scrapped continues to gain momentum.

The film "They Are Us" is only in planning at this stage, but already the petition's attracted more than 45,000 signatures.

The movie is said to centre around Prime Minister Jacinda Ardern and her response to the crisis, with Australian actress Rose Byrne poised to play her. 

National Islamic Youth Association co-chair Haris Murtaza told The Weekend Collective they started the petition because of a lack of consultation with those affected.

"Whatever decisions are to be made should be victim-centric, and we haven't seen that.

"Whatever movie is to come out, I don't think anyone except the victims should have a direct and continued input into it."

He says that, from his understanding, the Al Noor Mosque community hasn't been approached for consultation.

"Across the board, I'm yet to speak to someone who was spoken to or consulted on this matter."
