A Wellington City Councillor says the fight isn't over to remove the heritage listing from derelict buildings. 

RMA Minister Chris Bishop has signed off on the council's housing recommendations, unlocking the potential for up-zoning across the city. 

But an amendment to de-list 10 buildings to allow for demolition wasn't approved due to legal constraints. 

Councillor Ben McNulty told Mike Hosking he believes Bishop wanted to approve the changes but was constrained by the legal framework. 

McNulty says they'll keep trying.
