A Christchurch City Council committee wants an immediate halt to the demolition of heritage buildings because it believes many are coming down too quickly and without enough consultation.
The community recreation and culture committee on Tuesday voted three to two to write to the Canterbury Earthquake Recovery Authority asking for a moratorium on heritage demolitions.
Chair Yani Johanson said the authority's powers need to be reined in before more demolitions are rushed through.
And he said a moratorium should stay in place until a heritage recovery programme is put in place.
Some 37% of listed heritage buildings in central Christchurch have already been demolished.
