A former Christchurch City Councillor is calling for the Council to sell off the city's land, rather than money-making assets.

The Council's latest three year financial strategy would see it sell up to $750 million of the city's assets and introduce a massive rates hike over three years.

Aaron Keown says the Council's taking the wrong approach.

He says rather than sell off assets that still make the city a profit, they should be selling vacant land to be used in the rebuild.
