A charity concert for victims of the Christchurch terror attack is being discussed.

A local promoter says he is fielding calls from both Kiwi and international artists interested in taking part.

Brent Eccles says performers want to come together and do something for those affected by the shooting.

"Everyone wants to do something for Christchurch, and in fact for New Zealand, in terms of tackling our grief and standing together as one."

He says there are two reasons people want to take part.

"One is quite a cathartic thing. The second side is they can raise some money for victim support."

He did not reveal any names of those who have expressed their interest.
