Other risks

While these cover not all implications and risks associated with climate change, they are considered to pose some of the largest risks to New Zealand (taking into account hazards, exposure and vulnerability, as well as the scale of likely impacts and their probability of occurrence), and could affect large sections of New Zealand society.

Climate change will have other important implications (for example for human healthenergy generation and distributiontransport and infrastructure), but these are not discussed in detail in this report as they were not considered to be key risks at the same scale and with the same implications for near-term decision-making as the six areas covered in this report.
