Despite near universal recognition of the importance of climate change impacts on future generations, to date there has been no dedicated research on the effects of climate change on the population distribution in Aotearoa New Zealand. This paper reports on a review of international literature on the demographic impacts of climate change, with a particular focus on the likely implications for New Zealand. The paper argues that the greatest impacts are likely to be felt in terms of internal migration changes, with smaller but still significant effects on international migration and mortality rates.
