These researchers sampled participants from NZ electoral rolls and invited them to participate in a telephone interview, in which they were questioned about current workplace exposures. The investigation assessed differences in the prevalence of self-reported exposure to disease risk factors, including dust and chemicals, physical factors and organisational factors, between 2,344 Māori and 2,710 non-Māori workers. Exposure to occupational risk factors was more likely for Māori than non-Māori. Even when Māori and non-Māori were working within the same job, Māori were more likely to be exposed to physical factors such as heavy lifting and loud noise, and to organisational factors such as carrying out repetitive tasks and working under tight deadlines.
