Wellington Water crews responding to severe weather event and surface flooding

Wellington Water crews are actively responding to a band of heavy rain causing surface flooding and network impacts across the Wellington, Kāpiti Coast and South Wairarapa regions today.

Reports of flooding have been received this morning in Stokes Valley, Naenae, Upper Hutt, Plimmerton and Porirua areas. We currently have around 5 crews deployed across affected areas and working closely with local councils to respond as conditions evolve.

Heavy rainfall has led to surface flooding on key transport routes, please see NZTAs Facebook for thee latest updates on road closures.

Additional resourcing has been activated from across the region and are focusing on known flooding hotspots.

Crews are working as quickly as they can, but we are advising residents to bear with us as response times in some locations are being impacted by restricted road access.

Wellington Water is continuing to monitor conditions closely and will respond to all service requests as they arise.

We are keeping the public and impacted communities up to date via our website and social media channels. For further updates, please check the Wellington Water Facebook page.
