Colliers International's Evan Harris, of Christchurch, said more than 60 per cent of stage one had already been committed to before marketing had even started.
The development's first stage includes anchor tenant Kmart's 4000sqm store and a "main street" of fashion and retail stores.
Also approved is a town square which will be surrounded by a hospitality precinct including a tavern, restaurants and fast food joints.
There would also be a five-storey, 124-room building for either visitor or residential accommodation.
Earthworks started this week.

Canterbury contractor March Construction, as ordered by the High Court, is removing stored fill from Five Mile's original "Hendo's Hole" excavation.
Holloway expected the first stage to be completed by the end of next year or early 2018.
Holloway said the town centre should appeal to residents living beyond Frankton who would not need to travel to the Queenstown CBD.
