The Government has stepped up its monitoring of employers using migrant workers in the Christchurch rebuild.
Documents released under the Official Information Act reveal there are reports of migrant workers making payments for fake job offers. The Ministry of Business, Innovation and Employment also warns of the potential for those workers to be exploited as businesses compete for contracts.
Labour Minister Simon Bridges says he is aware of those reports and has asked labour inspectors to step their enforcement activity in the Canterbury region to manage any risk of exploitation.
