Health services were classified as ‘transplanting’, ‘intermediate’ or ‘remote’ depending on their degree of separation from a transplant centre. Multiple logistic regression modelling was used to assess the predictors of deceased donor waitlisting or living donor transplantation within 6 months after starting KRT. Web‐based mapping software was used to develop interactive geospatial maps.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The cohort was 7704 people newly starting KRT. Living in an intermediate [odds ratio (OR): 0.73 (95% confidence interval (CI): 0.61–0.88)] or remote [OR: 0.38 (95% CI: 0.27–0.54)) region and Māori (OR: 0.35 (95% CI: 0.28–0.44)], Pacific [OR: 0.32 (95% CI: 0.24–0.42)) and Asian (OR: 0.66 (95% CI: 0.50–0.87)] ethnicity were associated with a decreased likelihood of timely waitlisting or transplantation.
