NZ Transport Agency Waka Kotahi warns that while the road is currently passable for 4WD vehicles, worsening conditions are expected to force full closures on both sides of SH25 within hours.

Surface flooding has also been reported on State Highway 2 at Waikino in the Karangahake Gorge, and motorists are urged to take extra care or delay travel where possible.
