Ahuroa Road, Puhoi

Road status: open

7 March

Rodney’s most comprehensive and costly flood recovery road repair is complete after 20 months of construction. AT and our construction partner Downer thank neighbours for their patience while we undertook these repairs.  Ahuroa Road suffered several slips, including 8 major slips requiring extensive repairs.  The last site was completed in mid-February 2025 and the road is now fully open again. Below are some photos of the original slip, a map showing the major slip locations and finishing photos of the last slip completed.

You can watch a video on YouTube on the repairs (opens in a new tab). It highlights some great features of this work.

13 February 2025

The finishing touches are coming together for this last slip repair site on Ahuroa Road. The piles are very large and there's an impressive stormwater dropper installed to manage stormwater across the road.

Drainage work, pavement repairs and barrier installation are all expected to be complete in February 2025.

4 December 2024

The Downer team will resume work on Monday 9 December. They will be working on:

• the capping beam of the retaining wall
• soil nails
• drainage.

The team will take a break over the holiday period and return to the site on Monday 6 January 2025. The stop/go system will be operating during this time. The site will also be regularly checked for safety and functionality.
 
We are now into the last stretch of flood recovery work on Ahuroa Road. We expect it to be complete within the first quarter of 2025.
 
The road sealing team have also finished work (Stage 2B) along Ahuroa Road. They plan to start the Stage 2C seal extension works in March 2025.

8 November 2024

The site team remains disestablished while AT do back-end work around site anchors. We need to install these anchors into the hillside. This work is ongoing and making good progress. You will hopefully see the site team back on-site soon.

4 September 2024

At site RP7784, east of J Tolhopf Road, all piles have been built. The site team is temporarily away while details for the anchors are being addressed. A lane closure with stop/go traffic signals remains in place.

A Mason Contractors maintenance crew is also working on Ahuroa Road, doing extensive road rehabilitation and some minor slip repairs. The current stage, 2B, should be complete by the end of October 2024. The next stage is scheduled to start construction in January 2025 and will complete the remaining section to J Tolhopf Road.

21 August 2024

All piling work is now complete on the site east of J Tolhopf Road (site RP7784). Work on the timber lagging and drainage behind the new wall is now under way.

26 July 2024

Work east of J Tolhopf (site RP7784) is progressing, despite the weather and difficult ground conditions. To date, 38 of 46 piles have been drilled and concreted.

26 June 2024

Two slip sites, near 849 Ahuroa Road and the ‘hairpin’ bend, are set for final guardrail and line-marking work during the first week of July (weather permitting). This will only require a stop/go lane closure.

Work east of J Tolhopf (site RP7784) started on 27 May. Benching is complete and 4 piles have been installed. The team are encountering some hard rock similar to the other repairs along the road. Approximately 2 months’ work remains at this site. Stop/go and occasional stop/stop traffic management is occurring, but no delays have been noted as a result of these Downer works.

22 May 2024

Work on the main slip site near 900 Ahuroa Road has been completed, and the road is now open to residents on a stop/go basis while further slips are being worked on.

Construction works near 859 Ahuroa Road (on the northern side) began in early May, and one lane is closed. All timber piles have been installed and backfilling is under way.

Work beginning near J Tolhopf Road from 27 May is expected to take around 3 months.

Of 8 slips identified along Ahuroa Road, 3 are largely complete, with 5 remaining.

Another 2 slip sites are being repaired alongside road maintenance work further down the road towards Puhoi.

24 April 2024

Downer is planning to begin construction work opposite 859 Ahuroa Road (on the northern side) from Monday 29 April. Access will be maintained with a stop/go in place. This work is expected to take around 4 weeks.

Work continues near 900 Ahuroa Road with a full road closure. Work in this area is expected to take until 7 May.

The design and methodology for repairs to Ahuroa Road at RP 7.784, approximately 50 metres east of J Tolhopf Road, is progressing. Access will be maintained, but at times there may be a delay of 10 minutes when travelling through this section of road. During peak times, Downer will ensure access is uninterrupted. We will provide an update once a construction start date is confirmed. 

22 April 2024

All piling has now been completed with a total of 149 piles installed. Our priority now shifts to drainage works and the capping beam. The focus has now shifted to the concrete work on the capping beam of the retaining wall.  The heavy machinery within the road corridor restricts both vehicle and pedestrian traffic in the area.

8 April 2024

The construction team is installing the last of the 300m of piling and continuing to install the capping beam, poured to support the retaining wall and road.

18 March 2024

All 900mm 17m piles are in and Downer is now installing 900mm 12m piles using steel casing.

February 2024

Downer is making good progress, with 73 of 150 piles (some up to 17 metres deep) and 80 soil nails in place.

January 2024

Downer has now reestablished all construction equipment on site in preparation for the months ahead. The team is drilling and filling piles on the upper section of the site and the road will continue to remain closed for the duration of these works.

December 2023

Downer, on behalf of Auckland Transport (AT), continues to make progress on the remediation of the roadway on Ahuroa Hill. Since construction activities
began, a total of 16 piles have been drilled across the two sections. This is a considerable effort given the ground conditions which includes hard rock at a much lower depth than expected.

The construction team will be taking a break over the holiday period, from Thursday 22nd December 2023 returning on Monday 8th January 2024. During
this period the road will remain closed with all current temporary traffic management remaining in place.

26 October 2023

Ahuroa Road is proving difficult to repair. The original design was completed and works began in July 2023 on the permanent reinstatement. Unfortunately, the underlying rock layer is substantially deeper than thought, which has required a review of design options and a temporary hold on works.

AT is assessing six new design options and will select the most appropriate.  Once we have the preferred option, Downer and AT will be able to provide programme information to the community around timing and options.

AT remains committed to the successful completion of these works and expects that we will be able restart construction within four weeks and have the road open by April 2024.

10 October 2023

On Ahuroa Road, several major slips have completely closed the road through to Puhoi. There has been considerable progress on the slip at Ahuroa Hill RP8200-8600. Soil nails acting like anchors are in place, which means the slope is now stabilised against further erosion. Shotcrete (sprayed-on concrete) was completed in September, as shown in the image on the right. This specialised process involves the high-pressure spraying of concrete onto the retaining wall's surface, reinforcing its structural integrity. Some remaining components for this slip are currently in design.

21 September 2023

Completion of works is expected by February 2024.

7 September 2023

Ahuroa Road is being worked on in sections. Some sections have already been completed, some are in construction. One section near J Tolhopf Road, where there was a major slip, is in the design phase. Designs are being prepared to repair this section in conjunction with the other repairs.

There are several retaining walls to be completed and will be worked on in sections. Each section will be completed separately. Road sealing will be completed afterwards.

30 May 2023

• Final design has been approved. Works to start shortly.
• Road status - open from both ends with one section of road closed at J Tolhopf Road.

3 May 2023

• 8 underslips have been identified.
• Geotechnical investigation has been completed, and an inclinometer has been put in place.
• Preliminarily assessment and design for the road rebuild were completed and presented on 20 April 2023. We are now moving forward to the final design phase using the existing road alignment.
• Road status – open from both ends with one section of the road closed at J Tolhopf Road.

The final design process is underway for repairs needed on Dairy Flat Highway. We expect to begin construction work later this year.

Leigh Road, Leigh

Road status: open

7 March 2025

Slip repair work on Leigh Road started on 7 October 2024 and is now largely complete at the road level. Some minor remedial work is required below the road.  

13 February 2025

Slip repair work on Leigh Road started on 7 October 2024 and is nearly complete. Finishing touches during February include:

• steel waler beam installation
• chip seal remedial work
• line marking.

4 December 2024

All 51 piles were installed by the end of November and backfilling is being done. Drainage will be done during December. The road is now a single lane. This site is expected to be largely complete by the holiday break, with the road reopened to two lanes. More work may need to be done in the New Year.

8 November 2024

Work is progressing well. The team have installed the steel beams. They are now installing lagging and backfilling as they go.

15 October 2024

We started work on Leigh Road on 7 October 2024. The team created a bench below the road from which to work on the new retaining wall. Traffic is running on a single lane.

25 September 2024

AT and Downer are expecting to start work on Leigh Road, near Schollum Road, from 7 October 2024. The work will involve the construction of a retaining wall and shoulder repair work. A lane closure will be in place with stop/go operating.

We expect to complete work before Christmas.

Vector will also be operating either side of these works to move powerlines and poles. They will notify residents separately.

26 July 2024

Currently in design. Power cables near the slip site will impact design and construction methodology. We are working with Vector to address this.

Matakana Valley Road, Matakana

Road status: open, single lane with stop/go traffic management

3 April 2025

Work is progressing well and is currently on programme.

7 March 2025

Slip repair work at the 10th and final site on Matakana Valley Road began on 20 January 2025. This site is known as the waterfall site. The team are progressing with the installation of the block wall, breaking out rock for the foundations and then backfilling behind the blocks as they progress along.  

13 February 2025

Slip repair work at the 10th and final site on Matakana Valley Road, known as the waterfall site, began on 20 January 2025. We'll be installing a large concrete block wall approximately 5m high to enable the road to be widened, as well as working in the flow path below the road to manage the stormwater run-off. This work is expected to take 4 months to complete. To date the team have created an access ramp.  

21 August 2024

Site 9 (of 10 sites) has now been largely completed. This month, pavement and asphalting, line marking and guard rail installation have been completed.  Minor remedial work will be undertaken as the weather allows. Site 10 remains in design and work is planned to begin later in the year.

26 July 2024

This month, we installed 16 piles at site 9. All piling and retaining wall work is now complete, and pavement work will progress this coming month. Site 10 is still in design. Work should begin later in the year. 

26 June 2024

The team here are making great progress and are well ahead of programme. Eight sites have now been completed, with another one under way and one in design.

22 April 2024

Three slip sites have been repaired and another 5 are under way. 

At RP773 (below left) 17 steel UC beams have been installed, ready for the lagging to be installed. Further along the road 39 timber poles have been installed with another 8 to come (see below right).

At RP7037 timber poles and lagging is complete (below left), while at RP7730 all steel beams are in place and timber lagging and backfilling is under way (below right).

At RP7330 (below left) and RP7257 (below right) 17 beams have been installed, and curb and channel work are under way.

8 April 2024

Chip sealing has been completed on 3 sites (RP7330, RP7257 and RP5900) and 25 retailing poles are being installed and backfilled at RP7037. Ten steel beams have been installed at RP7730.

18 March 2024

The retaining wall at RO5900 is completed and kerb and channel will be installed next. Contractors are working on another three sites.

21 February 2024

Downer, on behalf of AT, will be undertaking permanent repair works on the 10 slip sites across Matakana Valley Road between numbers 732-952 from late February/early March. The construction work includes building retaining wall structures to reinforce and prevent further slips from occurring.

Works will begin near number 952 Matakana Valley Road, with the plan to progressively move through the area as each slip is remediated. Construction is expected to take 10 months, and we will provide regular updates on timelines.

• Hours of work 7am to 7pm, Monday to Friday
• Traffic management includes temporary traffic signals, stop/go and speed restrictions.

22 September 2023

Work commenced on Monday 18 September. After initial works, we found that a design change was required. Works are on hold while we refine the design. Traffic management will remain in place. 

20 September 2023

Work commenced on Monday 18 September. Our initial works will involve excavation and site setup before preparing for construction of the timber pole retaining wall. This work is expected to take 6 weeks. Once this is completed, Downer will make their way to the next slip further up on Matakana Valley Road. Resilience work in this area is still in the design phase. 

8 September 2023

Work is set to begin on Monday 11 September for a 6-week period. A lane closure will be required with a stop/go in place. 

17 August 2023

Mill Flat Road Bridge, Coatesville

21 March 2025

We're pleased to confirm the main contractor rebuilding Mill Flat Road Bridge has been awarded to John Fillmore Contracting (JFC Limited). We've since worked through the utility challenges that emerged just before the construction contract was awarded.
 
With solutions to these issues, we’re now working with Vector to implement changes to the infrastructure near the work site. They will be working at the site from 24th March to 18th April 2025. Once Vector has completed their remedial works, our contractor will take site possession soon after and will engage directly with the community about their work.
 
We expect construction of the bridge to take place near the existing temporary bridge, with minor disruptions to traffic while equipment and plant are delivered to the area. We'll keep the community informed about the bridge's progress on this page and with directly affected properties that neighbour the construction site.

5 February 2025

Things have progressed and a design is now approved with Vector. Following the changes from Vector works, we also submitted a consent amendment and are currently waiting on that to be approved. Once this is approved, we will be working with Vector to confirm a date for their work, so that we can then start ours.  At this stage, if the above goes as expected, we should be on site around April.

2 December 2024

During November, work has continued in preparation for the upcoming construction work.

Vector requirements for the movement of lines and poles need to be resolved before further construction progress can be made. The team are working hard to achieve this.

Unfortunately, the Vector relocation works are having an impact on our ability to award the contract. As soon as this is resolved, the contract will be awarded and work will begin.

Construction is now expected to start in early 2025.

AT sent a memo to update the Coatesville Transport Forum on 28 November. You can download the memo (PDF, 105KB).

8 November 2024

During October, ecologists monitored the site we will work in.

They were looking for:

• bats
• native skinks and lizards
• native bird nests.

Before removal of any trees, they were checked for nests. No bats, skinks, lizards or native bird nests were found. Monitoring for skinks and lizards will be ongoing throughout construction.

We are still working with Vector to determine a start date for their work. We are also yet to confirm a preferred contractor for the work.

26 September 2024

The Auckland Transport (AT) design team has completed their part. Our construction team will now take over. We expect to appoint a contractor in October.

Sub-contractors and team members will be doing surveys and preparation works until mid to late October. Pending the survey's findings, Treescape will be on site to do vegetation work.

Before construction starts, Vector needs to move the power lines and poles out of the work area near the bridge. Chorus will be on site with Vector to reconnect power to the new source. That may affect telecommunications and internet access as the changeover happens. Vector and Chorus will liaise with residents about this work.

21 August 2024

An update has been shared with Mill Flat Road residents and the surrounding community this week, following the completion of the design phase of work.

The letter provides detail on the progress to date, outlines the proposed design and highlights some of the key anticipated construction impacts. Download a copy of the Mill Flat Road letter (PDF, 740KB).

29 July 2024

The design stage is now complete. A resource consent application was lodged with Auckland Council in May, and a tender for construction is out. An update was submitted to the Local Board, and an update for the community will go out shortly. 

May 2024

A community drop-in session was held on 1 May 2024 to discuss the design to date. (See the April update for details on the design.) Download a summary of this discussion.

Mill Flat Road bridge replacement project

On 27 January 2023, the Mill Flat Road bridge was washed away during the Auckland Anniversary Weekend flooding event. As an emergency response, AT commissioned a Bailey Bridge to be constructed at the same location a week later.

Since then, AT has been investigating options for a permanent Mill Flat Road Bridge replacement, securing the necessary funding and undertaking a design process which includes planned intersection safety improvements on the Coatesville-Riverhead Highway.

What is planned

The Mill Flat Road Bridge current design includes:

• a 2-lane replacement bridge with 3-metre-wide general traffic lanes
• a single 1.5-metre-wide footpath on the southern (downstream) side of the bridge
• a slightly widened approach to the bridge on Mill Flat Road, providing greater sightlines
• no vehicle class or weight restriction
• the ability to be submerged and withstand a one-in-100-year flood event without being washed away.

The new bridge will be located slightly upstream of the current bridge to enable continued community access throughout its construction. It will be constructed in two halves, with traffic running on the temporary Bailey Bridge during the first half of the build. Traffic will then run on the first half bridge while the temporary Bailey Bridge is removed and the second half of the new bridge is constructed.

Concept bridge design and typical cross-section

Intersection Improvements - Mill Flat Road / Coatesville-Riverhead Highway

• The current design includes:
• A right-turn bay on Coatesville-Riverhead Highway leading toward Mill Flat Road.
• Slight widening of the road in this area, including retaining walls on the Rangitopuni Stream side, to accommodate the right-turn bay.
• Improved signage and intersection warnings either side of the intersection.

Next steps

• Finalise the detailed design - July 2024
• Award contract for physical works to the successful tenderer by October 2024
• Construction start - late 2024 for 12 to 16 months.

March 2024

A memorandum was provided to the Local Board in March 2024.

January 2024

Geotechnical investigations will be done at the bridge location from 30 January for approximately one week. Traffic management will be in place and delays are expected at times.

13 November 2023

AT presented a progress update to the Coatesville Transport Forum.

17 August 2023

Investigation phase under way to inform the design of the new bridge.

3 May 2023

• Temporary one-way bridge installed
• Project plan in development.

Pinchgut Road, Kaukapakapa

Road status: open under stop/go lane closure

3 April 2025

Site establishment work has begun and the team have started creating the bench area from which to work. We expect to finish at the end of April 2025.

21 March 2025

Slip repair work is expected to begin again from 26 March for 6 weeks (weather dependent) to:

• construct a retaining wall
• upgrade the stormwater
• repair the road itself.

The completion of a second site will also occur during this time. There will be a single lane closure and temporary speed limit of 30km in place throughout the duration of these works.

Residents will have access at all times, traffic controllers at either end of the road will help you. Please follow all signs, light signals and our traffic teams directions. Please allow for more time for travel.

13 February 2025

Slip repair work was made safe over the December and January holiday period, while details are confirmed for an additional section of work, where the road is undermined. The final touches and barrier installation will be carried out in conjunction with these additional slip repair works.

4 December 2024

Slip repair work near 111 Pinchgut Road began on 29 October 2024. We expected work to be finished within one month. But when excavating the slip site, the team discovered rubbish buried within the road base. The work area has been extended to fix the slope, and the rubbish is now removed. This site is expected to be largely complete by the holiday break, with the road reopened to two lanes. More work may need to be done in the New Year.

8 November 2024

Slip repair work near 111 Pinchgut Road began on 29 October and is expected to be completed within one month.

15 October 2024

We have repaired the first of 4 slips on Pinchgut Road. New edge markers are in place to highlight the edge of the road.

Work on the second slip near 111 Pinchgut Road will start on 21 October. The first step will be to build a retaining wall and repair the shoulder. We expect it to take one month to complete.

25 September 2024

We started slip repair work near 171 Pinchgut Road on Monday 23 September. We expect it to take approximately one month to complete. This work will involve the construction of a retaining wall and shoulder repair.

26 June 2024

Four slips remain on Pinchgut Road, with repairs starting soon. This work will follow the work currently being done on West Road.

January 2024

• Minor slip repairs at RP1015 and RP659 complete
• Preliminary site investigations complete, final designs in progress.

Takatu Road, Tāwharanui Peninsula

Road status: open

13 February 2025

Work on two sites on Takatu Road started on 4 November 2024 and were completed in December. Monitoring is ongoing at site 6109 and a new design will be developed if needed.

4 December 2024

Work on two sites on Takatu Road started on 4 November 2024. The new wall on site 7852 is complete, and the road area will be chip sealed and completed early December. On site 6109, the area was cleared to enable the works. Unforeseen ground conditions now mean that a redesign will be needed. The team are backfilling and making the site safe then will stop working until we have a new design. The road will be reopened to two lanes. We expect work to start again in the New Year.

8 November 2024

We started repairing the next slip on Takatu Road this week on 4 November. Downer, on behalf of AT, are undertaking the slip repair work near 617 Takatu Road. This will involve the construction of a retaining wall and shoulder repair.

A lane closure will be in place with stop/go operating.

23 October 2024

Downer will be repairing a slip near 617 Takatu Road from Tuesday 29 October 2024.

Work is expected to take approximately 6 weeks with a lane closure stop/go in place.

25 September 2024

We have identified two more slips. We have named them RP 7852 and RP 6109. Repairs are in the design stage. We expect to begin works later this year.

21 August 2024

Slip repair works are now complete on Takatu Road and the construction team have disestablished from the area. AT and contractor Downer would like to thank the community in this area for their patience while these extensive repairs were undertaken.

26 July 2024

Rock buttress works and guardrail installation are now complete.

Another slip was discovered on Takatu Road. Working in challenging wet conditions, the team installed 26 soil nails (marked with blue painted dots in the image) to stabilise the slip. In August, they will install mesh and spray shotcrete, as with other slips in the area.

26 June 2024

The team had to work with the tide to install the rock buttress during low tide. Work here is progressing well, and work on these initial slips should be completed soon.

22 April 2024

Working in challenging conditions using abseiling gear and special supports for access, the team have made great progress. Steel mesh has been placed over the slip area of four slips. Shotcrete work is now complete on 4 of the 5 slips that need it.

8 April 2024

Shotcreet has been completed on Slip 2, while soil-nail drilling and installation continues on slips 5 and 6.

18 March 2024

Repairs are being made to six sites and contractors are currently working on four, focusing no grouting and meshwork and soil nailing.

February 2024

December 2023

Construction activities are under way and focus on comprehensive remediation measures which include five soil nailed shotcrete walls and one mass gravity rock buttress to address the identified six slips.

All necessary equipment, including excavators and drilling gear, has been mobilised, vegetation removal is complete and nailing is under way.

Wishart Road, Helensville

Road status: open

18 December 2024

Our monitoring has found that the ground is still moving, even with the new drainage in place. This means further non-urgent repairs to the road are needed. We're currently confirming the repair plans in this location.

Vector need to straighten a nearby power pole. They'll also move another pole which will need to be relocated because of the road repair work. They'll start from 8 January 2025 and be in touch with neighbours to communicate any effects from the work. 

We'll be back touch next year once we've confirmed plans and programme for the repairs next year.

15 October 2024

We have installed drainage. We will actively monitor the site for an initial period of 3 months. If movement is detected, we will need to do further repair work.

25 September 2024

We have established an access track to the site and have started installing drainage.

4 September 2024

Work will start from Wednesday 11 September, taking approximately 4 weeks. The work involves the installation of a drainage system to redirect water from the slip area and surrounds.

Existing traffic management, which includes a lane closure with stop/go signals and temporary speed restrictions, will remain in place. This setup ensures that crews can carry out their work safely.

7 August 2024

We have been monitoring the site for the past year. Design for a solid drainage system to redirect water from the slip area and surrounds is under way, and the work should be carried out later this year. Once the new drainage is in place, we will actively monitor this section of the road for one to 2 years, looking for any movement of concern. If there is movement, we will finalise designs for a full repair at this location.
