This research takes a closer look at the effects of climate change on New Zealand agriculture and on the wider economy, including indirect international effects such as changes in the prices of goods exported from and imported to New Zealand, as well as carbon prices and policies. Economic loss from short term catastrophic events such floods and landslides is not investigated. Infometrics (2007) presented an initial quantitative analysis of some of the above issues. In this paper they update the part of that report that looked at the effect of climate change on agricultural commodity prices, by considering some new scenarios based on international research since 2007, and expand the time-period from 2025 to 2070.
