The information outlined below is current as at midday on 30/1/2026.

Please note next week's roadworks update will be shared on Thursday 5 February, a day earlier than usual, due to Waitangi Day on Friday 6 February.

Roadworks over the upcoming long weekends

All non-essential roadworks will pause over the Nelson Anniversary weekend, from midday today (Friday 30 January) until midnight on Monday 2 February.

Also next week, for the Waitangi Day long weekend, contractors will shut down sites from midday, Thursday 5 February until midnight on Sunday 8 February.

You may still see some of our crews out on the roads repairing potholes, responding to incidents, or carrying out essential work.

If you're planning on travelling over this period, remember to check our Journey Planner for the most up to date information.

SH6 Nelson to Greymouth

SH6 Korere

Road rebuild work will pause at this site from midday today (Friday 30 January) until Monday 9 February to avoid disrupting holiday traffic over and between the Nelson Anniversary and Waitangi Day weekends. However, a temporary speed restriction will be in place due to the uneven road surface.

After the Waitangi Day weekend, work will resume and continue until Friday 20 February. Crews will operate Monday to Friday between 7am and 6pm (although work may be required some weekends). There will be stop/go traffic management and a 30km/h temporary speed limit during work hours. After hours, a temporary speed limit will be in place due to the uneven road surface. Drivers can expect delays of up to 15 minutes.

SH6 Granity Narrows and O'Sullivan's Junction

Resilience work to help prevent rockfalls is pausing at these two sites near Murchison over the two holiday weekends and the intervening weekdays. During that time, at Granity Narrows a 50km/h speed limit is in place, while at O’Sullivan’s Junction both lanes are open and normal speed limits apply.

From Monday 9 February, crews will resume work at both sites, with stop/go traffic management and 30km/h temporary speed limits 24/7 until the end of May. Plan ahead for delays of up to 15 minutes at each site.
