Cover for the self-employed ACC CoverPlus Extra was introduced by ACC to provide cover for self-employed workers and business owners that would fail to otherwise be covered adequately by the standard ACC CoverPlus policy. It works by paying an agreed level of compensation, in the event of an injury resulting in time off from work. With this cover already agreed upon, any business would not have to prove loss of income and has certainty on their amount of cover in the event of an accident-related injury. The ACC CoverPlus policy was designed to cover employees at 80% of their net taxable income. With ACC CoverPlus Extra, a self-employed contractor would get 100% of the pre-agreed compensation paid until they were fit to return to full-time work. A business owner would be able to get compensation under ACC CoverPlus Extra even if the business continued to earn income whilst the business owner could not work because of injury. This would not be possible with the standard policy. Accredited Employers' Programme ACC allows certain companies to manage and fund the claims of its employees who are injured at work. In return, they are given a large discount in ACC premium. ACC says this provides companies with a financial incentive to have good health and safety practices at work. More than 140 New Zealand employers participate in this programme. ACC Futures Coalition and Green Party criticize this programme because creates a conflict interest for employers to wrongly deny claims and say it should be cancelled. Notable events Violence against staff ACC clients have occasionally threatened or attempted to harm ACC staff. In 1999, a staff member was fatally stabbed by a claimant at an ACC office in Henderson. In 2010, ACC logos were removed from company vehicles after several staff had their cars rammed or were "driven off the road by other drivers". The following year a threat against former chief executive Ralph Stewart led to a decision for security staff to be posted outside his home. There have been at least two threats to blow up a car bomb outside ACC offices and police have had to be called on several other occasions. In 2012, there were a total of 134 recorded threats made against staff—the majority against case managers "making difficult decisions".
