NZ Transport Agency Waka Kotahi (NZTA) is advising drivers in the Coromandel to expect delays to travel with the closure of SH25A today.

The highway is now closed in both directions on the Western side of the SH25A Kopu roundabout between the SH25A/SH26 intersection and SH25A/SH25.

Detours are available via SH25, or via SH26 to SH2 through Waihou and Whangamata.

People across the Waikato and Bay of Plenty are urged to to slow down, increase following distances and drive to the conditions.

Watch for surface flooding, slips, and debris and avoid driving through floodwaters.

People can check road conditions before heading out via the NZTA Journey Planner.
