Concerts and other events could be held in the residential red zone to take pressure off Hagley Park.
Mayor Lianne Dalziel floated the idea at a council meeting on Thursday that holding "concerts and various other events" would be a good transitional use of the land.
It is not the first time the red zone has been suggested as a location for concerts and other big events.
Hands off Hagley, the park's watch dog group, suggested last year popular noisy events should be hosted in the residential red zone to stop damage to the park.
Ms Dalziel said on Thursday holding events in the red zone would "re-engage the community in the area".
