Federated Farmers says its workforce of farmers removed about 1000 tonnes of mud and silt on Sunday from properties in New Brighton.
Spokesperson John Hartnell says 40 teams of farmers worked their way through properties in the suburb, which is almost unrecognisable after the quake.
He says many will return to their day jobs on Monday, but Federated Farmers will maintain a roster of farmers to continue the cleanup.
Mr Hartnell says the gathering point for farmers is the A & P showgrounds from 7am Monday.
He has also appealed for light loaders and diggers, which he says will help speed up the work.
An army of student volunteers gathered through Facebook is also helping in the suburbs.
