Making progress on Māngere flood resilience projects

Resource consents have been approved for two much-needed flood resilience projects in Māngere.

Neighbourhoods around the Te Ararata Stream in Māngere Central and Harania Creek in Māngere East suffered major flooding in 2023. The projects will reduce the flood risk for hundreds of homes, including some where there is a potential future risk to life.

"It's good to see the resource consent approvals process sorted so we can get on with work to improve resilience and protect the Māngere community from major flooding in the future," says Mayor Wayne Brown.

"Getting things fixed has always been a key focus of mine and these projects are an example of what can happen when we cut out the red tape. Once more, it will be paid for with money set aside as part of the Long-term Plan.

"Our Māngere communities were deeply affected by the 2023 floods. Upgrading the current infrastructure ensures any future damage is minimised and will provide confidence to those whose homes are highly prone to future flooding events."

Craig McIlroy, General Manager Healthy Waters and Flood Resilience acknowledges the collaborative effort and co-funding behind these projects.

"We're getting all the approvals for these projects in record time thanks to a massive team effort from our community and Government partners," says Mr McIlroy.

"This means we'll likely have spades in the ground by the middle of this year and hope to be finished end-2026."

Project details

Work in both catchment areas will address key blockage points so that in extreme storms rainwater can flow more easily out into the Manukau Harbour.

In Te Ararata, the culverts under the Walmsley Road bridge will be upgraded to increase water flow as well as a debris catching structure to reduce potential blockages. A permanent maintenance platform and accessway to the Mahunga Drive culverts will also be built to enable quicker and easier access for maintenance crews.

In Harania, the existing culverts through the embankment between Blake and Bicknell roads will be removed and replaced with a pipe-bridge and pedestrian bridge. This will enable the waterways around Blake Road Reserve to flow more freely and lessen the likelihood of flooding in the future.

"Knowing these improvements are on the way will be a huge relief for residents. We're committed to ongoing community engagement as the work progresses," adds Mr McIlroy.
