To derive New Zealand (NZ) population norms for the EQ-5D-5L and to examine the association between participants’ sociodemographic characteristics and their health-related quality of life.


Data from the 2018 NZ EQ-5D-5L valuation study (n = 2468) were used. Each participant’s 5-digit profile was converted to a single utility value using their personal value set. The profiles, mean utility values, and mean EuroQol visual analog scale (EQ-VAS) scores were summarized by dimension and disaggregated by age group and gender. Multivariable logistic and Tobit regressions were used to investigate the association between participants’ sociodemographic characteristics and the EQ-5D-5L dimensions, utility values, and EQ-VAS scores.


The mean utility value was 0.847 and the mean EQ-VAS score was 74.8. Of the 3125 possible EQ-5D-5L profiles, 25 profiles represented the current health status of the majority of participants (78%). The odds of having problems with anxiety or depression was greatest for people aged 18 to 24 years and decreased with age. People with a long-term disability or chronic illness had greater odds of problems on all dimensions and lower (poorer) utility values and EQ-VAS scores. Age, ethnicity, employment status, long-term disability, and chronic illness were associated with utility.


EQ-5D-5L population norms were derived for the NZ population using the personal value sets of 2468 participants. Consistent with other countries’ population norms, EQ-5D-5L utility values and EQ-VAS scores were associated with age, employment status, long-term disability, and chronic illness. These norms will support resource allocation decision making and help in understanding the health-related quality of life of the NZ population.
