The 2023 Auckland Anniversary weekend storm
An initial assessment and implications for the infrastructure system
As part of our work to understand resilience in infrastructure, we have undertaken an initial infrastructure assessment of the 2023 Auckland Anniversary weekend storm.
The purpose of this paper is to provide an initial view on:
- the severity of the January 2023 Auckland Anniversary weekend storm resulting in
- stormwater flooding in Auckland
- the impact of the storm on Auckland’s infrastructure
- the issues or weaknesses this event has raised about stormwater management and our infrastructure system.
Please note that this paper:
- is not intended to provide a full assessment of the impact of the flooding on Auckland, and
- does not comment on the impact on areas outside of Auckland
- was compiled in the days immediately following the storm, using the limited public
- information available at the time, meaning that we are necessarily relying on secondary sources of information
- was written before Cyclone Gabrielle reached New Zealand and so refers only to the Auckland Anniversary weekend storm.
