Govt Releases Independent Review on Flooding, Urges Urgent Action to Strengthen Flood Resilience

"We welcome the review’s findings and recommendations aimed at bolstering Wairoa’s resilience against future flooding events," said Minister Simmonds.

The independent rapid review of the Wairoa flooding event on 26 June 2024 has been released, Environment Minister Penny Simmonds, Local Government Minister Simeon Brown, and Emergency Management and Recovery Minister Mark Mitchell announced today.

"We welcome the review’s findings and recommendations aimed at bolstering Wairoa’s resilience against future flooding events," said Minister Simmonds.

The review found that the flooding was caused by a combination of factors, including the river backing up and overflowing, which led to both fresh and saltwater inundating low-lying parts of the town. It also identified shortcomings in the planning and management of the river mouth and bar, and called for more robust engagement between the Hawke’s Bay Regional Council, Wairoa District Council, and the local community on emergency preparedness.

"The report makes it clear that decisive and urgent action is needed," Simmonds emphasized.

To mitigate future risks, the review recommends that the Hawke’s Bay Regional Council work closely with Wairoa District Council and the community to develop a Wairoa River Bar Operational Plan. This plan will include monitoring actions, trigger thresholds to manage risks, and enhanced communication protocols, according to Local Government Minister Simeon Brown.

The recommendations will guide Lawrence Yule, Crown Manager for both councils, in overseeing flood protection works. "The operational plan will ensure more effective planning and risk management," Brown said.

Emergency Management and Recovery Minister Mark Mitchell highlighted the need for a more proactive approach to emergency preparedness. "Wairoa residents deserve the strongest measures and systems to face future weather events. I fully support the review’s recommendations and expect swift action from the responsible parties."

In addition, central government is considering recommendations from the review, which align with the recently announced review of the national direction on natural hazards. This will provide councils with clearer guidance on identifying and managing risks, directing development away from high-risk areas, and mitigating hazards through planning controls. It will also enhance transparency and data on natural hazards.

Minister Simmonds expressed her gratitude to the Wairoa community and the various councils and groups involved in the review, as well as Mike Bush for leading the independent review and providing the report.
