Update on state highway network

25 January 2026


 

Clearing material from the Kūaotunu Boat Ramp slip site

Updated information on SH25 closures

The following sections of State Highway are still CLOSED:

SH25 Kūaotunu to Kūaotunu West/Matarangi: Contractors are making great progress clearing this slip, however the site remains unstable and the road will not open until it is safe to do so. If the work progresses well and the weather is favourable we hope to open the road by late Wednesday 28 January.

SH25 Whangamatā to Whiritoa: This slip is complex and remains highly unstable with a large amount of water running through it, which means it will be more challenging to safely clear than initially thought. The earliest we currently anticipate being able to reopen the road is Wednesday 4 February. 

The following sections of State Highway are OPEN with caution (traffic management in place):

SH25 Coromandel town to Matarangi /Kūaotunu West
SH2 Paeroa to Waihī (Karangahake Gorge)
SH25 Hikuai to Whangamatā

The Coromandel network is already in a fragile state, and there is a risk that more loose material may come down. Recovery work will pause and roads may close at short notice if conditions worsen or become unsafe for crews on the ground.

With bad weather continuing its important people slow down, be patient and drive with care and to the conditions. People can stay informed by checking:

• Live state highway conditions on the NZTA Journey Planner
• Weather updates from MetService
• Advice from Civil Defence and emergency services

 

 

Contractors are working across the network on slips
