The Muslim Association of Canterbury has announced it will work to help producers of the film They Are Us; a film set to focus on the week 51 people were killed on March 15, 2019.
The new film has faced controversy over the past few days, with members of the public saying it is too soon for one of New Zealand's most tragic days to be depicted on the big screen.
Prime Minister Jacinda Ardern has also said it still feels "very raw".
Spokesman for the Muslim Association of Canterbury, Abdigani Ali, said after they questioned the timing of the film and raised concerns, the film producers contacted them.
"After consultation, the producers have shared the synopsis of the movie and listened to our concerns," Ali said.
"We have agreed to work closely with the producers to facilitate this process of consultation and any victims of the March 15 terrorist attack."
A statement from a producer for the movie, Ayman Jamal, said they were devastated by the pain and concerns caused the announcement of They Are Us.
"This was never our intention and we believe we owe a clarification to those families who lost their loved ones, survivors and witnesses regarding the film, its purpose and intention."
Filmmakers consulted members of the local Muslim community in Christchurch over a year ago, he said.
That consultation included speaking with the Imam (prayer leaders) at both mosques involved in the terror attack - Al Noor and Linwood mosques, respectively.
More than 20 victims were also consulted, he said.
"At the time, the Christchurch Muslim community was going through a lot and we were engaging only with those families who were ready to share their story with us at that time."
