Construction firms in Canterbury are being warned to make sure they're complying with employment law after an improvement notice was issued to one of them.
The Ministry of Business, Innovation and Employment issued the notice after an investigation found a worker for a construction company had not received his full wages, leave or public holiday entitlements.
The firm also had another employee who wasn't given an employment agreement.
Acting regional manager for the ministry's labour inspectorate Steve Watson, says the earthquake rebuild is creating a variety of work opportunities, but evidence shows rebuild operations often result in underpaid and overworked employees.
Mr Watson says the rebuild also poses a risk for migrant exploitation, and the ministry is keeping a close eye on firms.
