This bill is also about reversing some of National's 2010 changes. The bill also introduces changes that we meet our manifesto commitment to address the changes that National made when last in office, which unfairly disadvantaged tens of thousands of New Zealand workers. The changes in the bill will clarify the section 30 test for work-related gradual process, disease, or infection cover, and put the burden back on ACC to prove that a disease or infection is not work-related.
