Maintenance work ahead on SH1 through Rangitikei

Source: New Zealand Transport Agency

Road users travelling through the Rangitikei district are advised to expect some minor delays on State Highway 1 in the coming weeks due to planned maintenance and resilience works.

The Manawatū-Whanganui 2024/25 renewals season is nearing completion, with less than 2 months left.

Some crucial work on SH1 is still to be completed, with crews scheduled to be at different sites over the coming weeks.

The timing and location of these scheduled works has been specifically chosen to minimise disruption for travellers.

  • Utiku: From Monday 10 February, tree felling works will be taking place off the state highway near Utiku. Work to remove the trees will take place over 4 days, with crews working from 7am til 7pm. Temporary traffic management will be in place, with an occasional stop/stop (stopping traffic flow completely) while trees are removed alongside the highway. Motorists can expect delays of up to 10 minutes.
  • Taihape: Preseal repair works are taking place between Manu Road and Rauma Road, just south of Taihape, from Monday 10 February to Friday 14 February. Crews will be working from 8am til 5pm. Stop/go temporary traffic management and a reduced speed limit of 30km/h will be in place, with delays of up to 15 minutes expected. Following these works, crews will return to complete resealing works before the end of this renewals season. This will be communicated closer to the time. 

Once these works are complete, further road maintenance is planned later in the month for SH1 near Mangaweka and Bulls. 

  • North of Bulls: From Monday 17 February – Friday 28 February, planned road maintenance work will take place on SH1 near the intersection with Wellington Road. Crews will be working from 6am til 6pm each day. Stop/go temporary traffic management and a reduced speed limit will be in place, with delays of 5 minutes expected.
  • Bulls: From Wednesday 19 February, crews plan to complete a 3-week road rebuild on the passing lane north of Watson St, Bulls. This road renewal work will take place each day, with crews working from 6am til 6pm each day. The first week of work involves contraflow  (allowing both directions of travel) and the remaining 2 weeks of work involves stop/go temporary traffic management, with delays of 5 minutes expected.
  • Mangaweka: Road rebuild works are planned for the passing lane near Mangaweka, from Thursday 20 February to Thursday 20 March.  These renewal works will be completed under contraflow so minimal disruption is expected for road users.

NZ Transport Agency Waka Kotahi acknowledges State Highway 1 has seen a lot of construction activity over the past few months during the renewals season and we really appreciate people’s patience during this work to increase the resilience of the network.

The upcoming works are weather dependent and may be postponed or rescheduled at short notice. Changes in programming will be communicated on our online channels such as NZTA’s Journey Planner.

SH30/Wharenui Road intersection upgrade starting

Source: New Zealand Transport Agency

NZ Transport Agency Waka Kotahi (NZTA) advises work begins Monday (10 February) to upgrade and install traffic lights at the intersection of State Highway 30 (SH30) Te Ngae Road and Wharenui Road.

NZTA advises Rotorua drivers that, as part of this work, a short section of Wharenui Road, between SH30 Te Ngae Road and Reeve Road/Glenfield Road, will be closed to through-traffic.

This closure will be in place from Monday 10 February, not Monday 3 February as earlier stated, until the project is completed in May this year.

Access for residents, pedestrians and cyclists will be maintained. A detour will be in place for other traffic.

Temporary footpaths and pedestrian access will be available and clearly signposted.

Residents, service providers, and visitors will be able to take vehicles into the closed section of Wharenui Road from the Reeve/Glenfield intersection.

All other traffic will need to use Brent Road or Coulter Road to access eastern Wharenui Road, Reeve Road and Glenfield Road, and any connected roads.

While this work is underway a temporary speed limit of 30km/h will be in place on SH30 Te Ngae Road through the work zone.

More information about additional traffic management will be shared as construction progresses.

State Highway summer maintenance continues in Marlborough

Source: New Zealand Transport Agency

People travelling between Nelson and Blenheim can expect to see road works on State Highway 6 into March as investment into the region’s highway infrastructure continues.

These works are critical for ensuring the transport link between Blenheim and Nelson is kept safe and reliable for all road users.

Work will be getting underway at Havelock and near Pelorus from next week.

These works are critical for ensuring the transport link between Blenheim and Nelson is kept safe and reliable for all road users.

SH6 Pelorus works

From Monday 10 February, to Friday 21 March, Monday to Friday, 7am to 6pm, contractors will rebuild a 1.6-kilometre section of the highway near Pelorus.

They will remove the top layer of the road, lay new gravel, and then apply new chipseal on top. The end result is more stable and improved road surface.

Drainage works will also be completed, and the shoulder of the state highway will be widened. Road users can expect delays of up to 10-minutes during work hours until this work completed.

To ensure the chip-sealing is successful, this work must be done during the day when the weather is warmer.

A 30 km/h temporary speed limit will be in place while the work is underway. All drivers must follow it – it is there to protect the road surface, keep drivers safe, and protect vehicles for stone chip damage.

This work is deliberately planned to minimise disruption for drivers and has been timed to coincide with the State Highway 6 Whangamoa Saddle closure when there will be less traffic on the road.

People travelling between Nelson and Blenheim are also reminded of the upcoming night closures of the Pelorus Bridge on Sunday 23 February.

SH6 Havelock works

From Wednesday 12 February, to Sunday 16 February, between 7pm to 7am, contractors will also carry out nighttime asphalting work on State Highway 6 through the Havelock township. Work will be underway from just north of Neil Street to Allied Petrol. Stop/go traffic management will be in place during work hours with delays of up to 10 minutes.

Drivers are urged to check road conditions before they travel and plan their journeys accordingly. This is especially important for people with Picton ferry connections.

Upcoming SH6 work schedules and locations

Scientists hit the water for Maaui dolphin population survey

Source: Department of Conservation

Date:  07 February 2025

This research, conducted every five years, uses a proven genetic mark-recapture method to estimate the Maaui dolphin population along the west coast of the North Island. DNA samples will be collected from live, wild dolphins using a small biopsy dart, providing essential information about population size, genetic diversity, and movement patterns.

“The Maaui dolphin is critically endangered, and every sighting or sample contributes to our understanding of the species and its future survival,” says Cara Hansen, DOC Ranger.

The most recent abundance estimate, completed in 2021, indicated there were approximately 54 individual Maaui dolphins over the age of one year in the water off the North Island’s west coast (the animals’ known habitat). This new survey will provide an updated estimate to help track changes in the population and inform conservation efforts.

The survey will be carried out over two summer seasons, in 2025-26 and 2026-27, with field teams operating between the entrance of Kaipara Harbour and the Mokau River in Taranaki. Staff from DOC’s Taranaki, Auckland, and Waikato districts, the Marine Species Team, the University of Auckland, and Ngaati Te Ata will collaborate on this important project.

The public can also play a role in conservation efforts by reporting any sightings of Maaui dolphins and being aware of the threat that toxoplasmosis has on Maaui dolphins. The dolphins have a distinctive round dorsal fin, often likened to an ear from the cartoon character Mickey Mouse.

“Real-time reports help our field teams understand where the dolphins are being seen and improve the success of our survey,” says Cara.

Sightings can be reported through DOC’s hotline at 0800 DOC HOT (0800 362 468) or online Marine mammal sighting form.

EIT Tutors teach invaluable skills to remote islands of Tokelau | EIT Hawke’s Bay and Tairāwhiti

Source: Eastern Institute of Technology – Tairāwhiti

2 minutes ago

Two EIT tutors have spent six weeks in Tokelau, teaching essential plumbing and automotive maintenance skills to support the remote island community. 

The program, delivered by Stu Hannam and Chris Olsen last year, focused on equipping locals with the practical knowledge needed to maintain vital infrastructure and improve their quality of life.

Over the course of their stay, the tutors taught 45 students, repaired 60 outboard motors, 15 cars, 5 motorbikes, 5 chainsaws, generators, and a jackhammer. They also worked on plumbing repairs for community buildings, the local hospital, houses, schools, and a hotel. 

EIT Automotive Tutor Stu Hannam with students in Tokelau.

The journey to Tokelau was an adventure in itself. After flying from New Zealand to Samoa on August 31, the pair boarded Mataliki, Tokelau’s ferry, for a 46-hour voyage across rough seas.

They arrived at the atoll of Atafu on September 6, where they spent 16 days teaching, before moving to Nukunonu, the largest atoll, for another 18 days. 

For Hannam, an automotive tutor, the trip was about addressing a critical need. “The people didn’t really know how to fix things themselves,” he said.

“They fixed things only when they broke. I showed them how to service their outboards to make them safe at sea. It’s crucial because they rely on fishing for food and survival.” 

Olsen, a plumbing tutor, emphasised the importance of water management in the islands.

“Water is their lifeline. They don’t have natural groundwater, so everything is collected in tanks,” he explained. “We taught them how to fix leaks and install proper spouting to catch rainwater. A lot of the work involved tweaking their existing knowledge and showing them how to do things properly.” 

The impact of their training extended beyond individual skills. On Nukunonu, the Taupulea (Council of Elders) decided to establish a dedicated plumbing team from Olsen’s graduates.

“It was awesome to see the community so happy about the knowledge their people gained.” 

The tutors fully immersed themselves in Tokelauan culture, participating in activities such as church services, a dance competition, and cricket matches.

“The singing in church was amazing,” Olsen recalled. “And, yes, we got roped into dancing, which was a lot of fun.” 

For both tutors, the experience was profoundly rewarding.

“It really reinforced how we, as educators, can make a huge difference in remote communities,” Olsen said.

Hannam agreed, noting how appreciative the Tokelauan people were. “They’ve told me their motors are running better than ever, and they feel safer going out to fish.” 

Their time on Nukunonu concluded with a ceremony attended by the Ulu-o-Tokelau (Head of Government), Alapati Tavite, who praised the success of the program. 

While no official plans to return have been confirmed, both tutors hope this is just the beginning.

“There’s still a third atoll we didn’t get to because of time constraints,” Olsen said. “If given the chance, we’d love to continue this work.” 

Andrew McCrory, Assistant Head School of Trades and Technology, said teaching these valuable Plumbing and Automotive Skills was a huge success for EIT and the Tokelauan Communities. 

“Student engagement and embracing the community is important in these situations, and full credit must go to Chris and Stu for taking time away from their families to make this happen. They have both laid the groundwork for more tertiary education in Tokelau.”

New psychosocial risk infographics for high-risk sectors

Source: Worksafe New Zealand

WorkSafe has developed infographics on psychosocial risks in the high-risk sectors of agriculture, construction, forestry, and manufacturing, as well as psychosocial risks that affect all New Zealand workers.

Mental health is an important workplace health and safety issue. Businesses have a responsibility under the Health and Safety at Work Act to manage both physical and psychosocial risks.

Psychosocial risks arise from poor work design and challenges in the social and physical environment, and they may result in negative psychological, physical, and social outcomes.

These infographics help businesses to easily find and understand data on psychosocial risks relevant to their industry. Sharing information like this is part of our engagement function, to empower businesses and workers to improve health and safety practice.

The infographics collate existing data into an easily digestible format. The data is from WorkSafe’s workforce segmentation and insights surveys, New Zealand psychosocial survey, work-related suicide report, and mentally healthy work concerns notified to WorkSafe.

The following information is available about each sector:

  • Psychological harm
  • Self-rated health
  • Work-related suicides and significant work-related stressors
  • Offensive behaviours such as bullying and threats of violence
  • Policies around bullying, harassment, and violence
  • Protective factors
  • Mentally healthy work concerns that WorkSafe has received
  • Employer attitudes
  • Employers’ health and safety maturity, perceptions, and practices.

Reminder: Full night closures begin on Wellington State Highway 1 urban motorway next week

Source: New Zealand Transport Agency

Wellington drivers need to be ready for major maintenance works on Wellington’s urban motorway next week.

Full night closures, north and southbound, are planned from Sunday 9 February to Thursday 13 February, between 9pm and 4:30am.

The works are weather-dependent, so closures may be delayed into the following week if required.

While the resurfacing and maintenance work is underway, the motorway will be closed to northbound traffic between Karo Drive and Ngauranga Interchange.

It will also be closed to southbound traffic between the Terrace offramp and Vivian Street.

Drivers will have to use alternate routes to get in and out of Wellington city, and it means it will take drivers a little longer to get in and out of the central city.

Road users must plan ahead and allow extra time for their trips– particularly if they are heading to Wellington Hospital or Wellington Airport.

Planned works

Resurfacing work is planned for around five lane kilometres of the motorway’s northbound lanes between Aotea Quay onramp and the Ngauranga Interchange. This will help make the  road’s surface safer and smoother.

To make the most of the closure and ensure as much work can be completed as possible, the Terrace Tunnel will also be closed for its annual Building Warrant of Fitness (BWoF) inspection. Because it is a vital piece of infrastructure, the tunnel must be inspected, tested, and maintained regularly.

Road crews will also complete  other essential maintenance work during the closures. This includes renewing digital signs, streetlight maintenance, sign gantry assessments, carrying out structural inspections on overbridges and on and offramps, assessing safety barriers, clearing drains, removing graffiti, and clearing rubbish.

Works schedule and detour routes

  • Sunday, 9 February to Thursday 13 February. 9pm – 4:30am.
  • Traffic management set up from 7 pm – drivers can expect delays during this time.

Northbound closure

  • SH1 Urban Motorway closed between Karo Drive and Ngauranga Interchange
  • All northbound on and offramps will be closed – Clifton onramp, Tinakori onramp, Tinakori offramp, May Street onramp and Aotea Quay onramp. 
  • Drivers should detour via Karo Drive – Willis Street – Customhouse/Waterloo/Aotea Quay – Hutt Road – Ngauranga Interchange. See the detour map below.

Southbound closure

  • SH1 Urban Motorway closed to southbound traffic between The Terrace offramp and Vivian Street
  • Drivers should detour via The Terrace offramp and Ghuznee/Victoria/Vivian Streets. See the detour map below.

It’s business time for Golden Bay’s Birds Hill bump

Source: New Zealand Transport Agency

Golden Bay residents can expect to see contractors on site on State Highway 60 at Birds Hill next week with resilience work to start on the Birds Hill landslide.

The slip reactivated  in 2017 and has continued to gradually move, creating  a large hump in what was the left-hand lane of the highway. While the highway is open to two lanes at the slip site, it has been under a long-term 50 km/h temporary speed limit.

SH60 Birds Hill slip site.

Rob Service, System Manager Nelson/Tasman, says work will begin next week (10 February) to repair the site and improve its stability.

“Any future landslide movement poses a real risk to State Highway 60 in an area where there are no alternative detour routes. Maintaining and preserving access to Collingwood and western areas of Golden Bay is critical.”

“To reduce the risk, contractors will carry out substantial drainage work at the slip site above the highway. This includes building horizontally drilled drains into the slip, constructing cut off drains above the hump, and redesigning and resurfacing the road to allow the current 50 km/h speed limit to be removed,” Mr Service says.

However, he warns the work will not remove the current hump at the slip site.

“The hump is at the toe of the slip and geotechnical assessments show it provides stabilisation, reducing ground movement. To remove it would likely increase slope instability and increase the risk of more movement, particularly after wet weather.”

“In this case it is better to work with nature and leave it in place. Site studies have shown the slip’s stability is sensitive to groundwater. So, improving the drainage and removing water from the slope is the best and most cost-effective option,” Mr Service says.

He says the work will affect traffic travelling between Tākaka and Collingwood.

“For a project of this scale, it is unavoidable. The project site will be under stop/go during the day. Drivers will still be able to get through but can expect short delays. Outside of work hours, the highway will be open to two lanes.”

“Weather permitting, we expect the project to be finished by late April. So, please bear with us while our contractors work hard to get this job finished,” Mr Service says.

Works schedule

  • Monday, 10 February to Thursday, 24 April (Weather dependent). Monday to Saturday, 7 am – 7 pm
  • Stop go traffic management and  30/km/h temporary speed limit
  • Road open to two lanes and 50 km/h temporary speed limit outside work hours
  • No work will be done during the Easter Holidays
