A multi-company consortium led by Opus has been selected to design and develop central-city anchor projects for Christchurch's rebuild.
The consortium will be responsible for creating an Avon River precinct and two other areas designated as green spaces under the city's redevelopment plan.
Canterbury Earthquake Recovery Authority chief executive Roger Sutton announced the successful tender on Thursday.
Mr Sutton said the consortium would also help with flood management for the river.
Work will begin early in the new year on concept design for the projects and physical construction is due to begin later in the year.
The projects are expected to include parks, cycleways and children's play areas along the Avon river.
Mr Sutton says the parties chosen have worked on riverside projects around the world, in countries like England and China.
