Purpose: Centralisation of lung cancer treatment can improve outcomes, but may result in differential access to care for those who do not reside within treatment centres. Methods: We used national-level cancer registration and health care access data and used Geographic Information Systems (GIS) methods to determine the distance and time to access first relevant surgery and first radiation therapy among all New Zealanders diagnosed with lung cancer (2007–2019; N = 27,869), and compared these outcomes between ethnic groups. We also explored the likelihood of being treated at a high-, medium-, or low-volume hospital. Analysis involved both descriptive and adjusted logistic regression modelling. Results: We found that Māori tend to need to travel further (with longer travel times) to access both surgery (median travel distance: Māori 57 km, European 34 km) and radiation therapy (Māori 75 km, European 35 km) than Europeans. Māori have greater odds of living more than 200 km away from both surgery (adjusted odds ratio [aOR] 1.83, 95% CI 1.49–2.25) and radiation therapy (aOR 1.41, 95% CI 1.25–1.60). Conclusions: Centralisation of care may often improve treatment outcomes, but it also makes accessing treatment even more difficult for populations who are more likely to live rurally and in deprivation, such as Māori.
