Over the course of the project the company removed approximately 70,000 tonnes of silt from the river.
The aim of the works was to restore capacity lost after the earthquakes and through ongoing silt deposits.
By restoring the capacity of the channel, the risk of properties and streets flooding during heavy rainfall is now at minimum, the local officials said.
The Heathcote River dredging project helped reduce the severity of flood events by deepening and widening of the river channel.
