Kia ora and welcomeKia ora, Welcome to this week's issue of the Nelson/Tasman state highway planned roadworks update. With our summer maintenance programme now underway, you will see a lot more activity on our state highways.

Please feel free to share this newsletter with whānau and friends, anyone can sign up to stay informed. The information outlined below is current as at 12:10pm on 3/10/2025.

Summer maintenance season is underwayThe roadworks season is underway in the top of the South Island, and you can expect to see contractors hard at work at multiple locations over the coming months. In Nelson/Tasman, approximately 35 lane kilometres of road renewal work will be completed between now and the end of March 2026, including:
The flood damage from June and July is being factored into this season’s work. There’s a lot of activity across the region but we have planned as best we can to minimise disruption to your journeys. Where possible we will coincide these repairs and ongoing resilience work with road rebuilds and resurfacing works. This is the exact approach we will be taking on State Highway 60 over the Tākaka Hill and on State Highway 6 Whangamoa Saddle. The same applies on State Highway 6 heading south from Kohatu Junction. Read our media release for more information about the work we have planned in Nelson/Tasman.

Roadworks terminology explainedLane kilometre refers to the amount of highway lane being worked on, not the full width of the road. For example, renewing both lanes of a highway over a one-kilometre distance is equivalent to two lane kilometres of renewal. Road rebuilding (also called pavement rehabilitation) is a full reconstruction of the road. Both the surface and the layers underneath are removed and replaced - sometimes using recycled materials from the original road. After a road is rebuilt with a chipseal surface, crews return about 12 months later to apply a second coat. This helps strengthen the surface and improves waterproofing, making the road last longer. Resurfacing means removing the top layer of the road and replacing it with a new, pre-mixed layer of stone, bitumen, and other materials. This creates a smoother, more durable surface. Resealing involves spraying a layer of hot bitumen or emulsion onto the road, before spreading stone chips over it. These chips take time to settle into the surface, and any loose ones are swept away a few days later. Resilience work proactively improves the transport network by making sections of the state highway network less susceptible to the impacts of severe weather events. |

Signage and barrier installation on SH6 between Nelson and Blenheim From Monday 6 October until Friday 31 October contractors will install new signage and barriers at several sites between Woodbourne and Hira from 7am to 7pm on weekdays. Only one site will be worked on at a time to minimise disruption. Stop/go traffic management will be required at some of the barrier installation sites and 30km/h speed restrictions will be in place. Expect short delays. |

SH6 Nelson to GreymouthSH6 Spooners Saddle SH6 Spooners Saddle remains closed on weekdays from 7:30am until 5pm between Wai-iti Valley Road and North Road for the removal of wind fallen and damaged trees adjacent to the state highway. This weekday closure will remain in place until Friday 10 October. The detour route for southbound travel is via Wai-iti Valley Road, Stock Road, Valley Road, North Road - the reverse for northbound vehicles. This detour will add 10 minutes to travel times.
Our team is maximising the closure by carrying out maintenance work including clearing drains and culverts, and repairing catch fences. |

SH6 Dellows Bluff - west of Murchison The overslip repair work at Dellows Bluff is now complete and all traffic management has been removed from site. Thank you for your patience and understanding as we’ve carried out this work. This has been a geologically challenging site and our teams have done an excellent job. There is still some work to do onsite including culvert cleaning, resealing and line marking, but this will be carried out under stop/go traffic management at a later date. |

SH6 rockfall resilience work at Granity Narrows and O'Sullivan's Junction Rockfall resilience work will begin on Monday 6 October at two sites near Murchison - one at the Granity Narrows on State Highway 6 between Kawatiri and Owen Junction, and the other near O’Sullivan’s Junction - also on State Highway 6. Extensive rockfall protection will be installed at both locations, with around $8.6 million to be spent on the projects. This will involve rock scaling to remove loose rock, as well as installing rock bolts and mesh to stabilise the rock faces and reduce the risk of further debris falling onto the road. Stop/Go traffic management and 30 km/h temporary speed limit will be in place at both sites 24/7 until the end of May 2026. Plan ahead for 15 minute delays. At times, traffic will be held in both directions when controlled rock clearing is underway. The road will be open to two lanes over the Christmas / New Year holiday period. |

SH60 Tākaka Hill, Riwaka side, approx. 4 km uphill from Riwaka Valley Road Plan ahead for delays of up to 20 minutes over SH60 Tākaka Hill as recovery work following the June and July storm events continues 24/7. The temporary traffic lights covering multiple sites have been reinstated after the fibre optic cable connecting them was intentionally cut last weekend. This act of vandalism has been reported to Police. This behaviour is dangerous and unacceptable. When the cable is cut, the lights revert to the default red setting. This creates uncertainty for road users and creates a safety risk for our team on the ground. The temporary lights have been installed to make the road safe for all motorists while our crews work hard to rebuild the highway before the summer holiday period. |
