Taranaki state highway update

Saturday 18 October to Friday 24 October

17 October 2025

Roads to reopen this afternoon

Crews have been working hard to clear slips and restore access to state highways across the regional boundary between Taranaki and Waikato following this week’s heavy rainfall.

A massive thank you to our hardworking teams for their dedication, and to the community for staying clear of affected areas to allow crews to operate safely and efficiently.

SH3 Awakino between Mokau and Piopio will reopen at approximately 3pm today.

SH4 between Eight Mile Junction (the intersection between SH3 and SH4) and Taumarunui, and SH43 between Whangamōmona and Taumarunui will both reopen at approximately 5pm today.

These highways will have temporary speed limits in place over the weekend, with multiple sites under stop/go traffic controls Monday to Friday while repairs are completed. Repairs are expected to take 2-3 weeks.

Road users should plan ahead for additional travel times of approximately 40-60 minutes in this area. Continue to delay travel in this area unless absolutely necessary.

Please drive to the conditions and follow all temporary traffic management – it’s there to keep you and our crews safe.

More rain is forecast across parts of the region in the coming week. Slips and other hazards can occur without warning, so please drive to the conditions.
