Daytime closures for SH25A Kōpū-Hikuai in November
Published on 23 September 2025
Daytime closures are needed on State Highway 25A (SH25A) for 2 weeks in November 2025 for a major road rebuild.
The work will take place from Monday 10 November until approximately Friday 21 November, with the state highway closed from 8am to 5pm Monday to Saturday.
The 2 sites, each approximately 1km long, between Kōpū and Hikuai, are narrow with steep drop-offs, and the work cannot be done safely with the road open.
The road will reopen under single lane and stop/go each evening from 5pm and on Sunday 16 November. Delays can be expected. Dates are weather-dependent.
Critical services such as first responders and school buses will be escorted through the site during the day. All other vehicles will be required to take the SH25 detour which adds an hour to the travel time.
“We hope getting these dates and times confirmed well in advance will help people plan their Coromandel travel during that fortnight,” says NZ Transport Agency Waka Kotahi (NZTA) Regional Manager for Maintenance and Operations, Roger Brady.
“We recognise SH25A is a vital link across the peninsula and we would not be closing the road if there was any other way to get this work done safety and quickly.
“The top priorities are the safety of our people and road users, and getting the highway open as quickly as possible.
“We investigated doing this work with stop/go or controlled openings or allowing convoys of traffic through. However, these options are difficult to accommodate at such confined sites and would mean the job would take much longer with increased risk to contractor staff and road users.”
SH25A was closed for most of 2023 after a slip required a new bridge to be put in place.
“The emphasis in 2023 was all about resilience and our contractors got a lot of other work completed on the road during the closure,” Mr Brady says.
“This work was not programmed, funded or resourced at that time.
“We have a busy summer maintenance season across Coromandel and always aim to get works done before the busy holiday period, while trying to minimise inconvenience to road users.’’
This work will follow on from the SH25 closure on the west coast of the peninsula for the deck replacement on the Boundary Creek Bridge.
