Sections 181 to 189 have three main goals. First, they aim to help prevent injuries and help people get better if they are injured. Second, they want to lower the costs of work-related injury claims and the money employers have to pay. Third, they want to create ways to measure how well work-related injuries are being handled.

These goals are achieved by letting some employers, called accredited employers, take care of their employees' work-related injuries themselves. This means these employers pay for the benefits their workers get if they are hurt at work. But before they can do this, the employers must talk to their employees or the people who represent them, like unions. This includes any union that is officially registered under the Employment Relations Act 2000.

When accredited employers do this, they look after their injured workers for a certain period of time, which is called the claim management period.
