"It's a question of not accepting exploitation as part of something that's in our community that we just live with... we should be taking strong steps not only at government, but also in our community to eradicate it," Mr Milne said.
"Behind that $10 main is a social cost, and that social cost might be that workers are not being paid properly... I think people need to choose wisely and ethically," he said.
"Business owners must ensure they are acting lawfully and that each employee is receiving their minimum entitlements. Those that do not will be subject to enforcement action, which can include penalties of up to $10,000 for individuals and $20,000 for companies."
Equal Employment Opportunities Commissioner Jackie Blue said the exploitation of migrant workers in Christchurch had been a focus for the Human Rights Commissioner.
"We can't be bystanders any more, we've all got to take responsibility, it's everyone's problem. If there are people who are concerned about exploitation of migrant workers they need to say something to someone, obviously if they can't say it direct to the employer they should contact MBIE."
Last year a chain of liquor stores in Auckland were found to owe more than $200,000 in employment law breaches.
MBIE froze the employers assets and managed to get some of the money back to the workers who had been exploited.
