The migrant workers have been paid compensation. They all have current work visas for working at other employers.
Immigration New Zealand general manager Peter Devoy said it didn't tolerate employers who exploited migrant workers.
"The overriding principle is that migrant workers have the same employment rights as all other workers in New Zealand," he said.
"We will not tolerate employers who exploit migrant labour for their own commercial advantage and will not hesitate to prosecute in cases where warranted."
Devoy encouraged anyone forced to work in New Zealand illegally for less than the minimum wage or for excessive hours to contact Immigration NZ.
