The investment would ensure the group's red meat production remained competitive on a global scale, Mr Surveyor said.
"This investment also reflects our commitment to our eight processing plants from Lorneville near Invercargill to Dannevirke in the southern Hawkes Bay," Mr Surveyor said.
The project was part of Alliance's Manufacturing Excellence programme, which also prompted the announcement last month of a $10.6million investment at the group's Dannevirke plant, he said.
The custom-built primal/middle cutting technology featured an X-ray unit which analysed each carcass and instructed the two cutting machines where to cut.
The technology was already in place at the company's Smithfield plant in Timaru and the Pukeuri plant.
A spokesman for the company said this project was "in no way related" to the workplace accident at the Smithfield plant on March 17, in which an employee's hand was cut off.
