Any injury including hernias you have while at work is covered by ACC, though a hernia that has developed over a period of time may not.
Some employers have their own injury insurance, they are known as accredited employers. They sign a contract with ACC taking responsibility for the management and costs of their employees’ work related injuries and illnesses. Your hernia injury will still be treated in the same way as through ACC. Your employer should give you the information you need to make a claim, please pass this information on to your GP and The Hernia Clinic when you make your appointments.
