January works update
Working to schedule, the construction team completed essential work near Ngapipi Bridge, poured concrete for the new shared path, and reopened the road as planned.

Ngapipi Road works
In early January, the foothpath, kerb and channel, and a small part of the sea wall was removed for the future shared path.
Near the water’s edge, we are building an 800mm extension to the existing sea wall. This will form the edge of the shared path. We are also installing a ground beam that will tie back the existing wall.
We acknowledge that there were delays to traffic during the morning peak, especially for Ngapipi Road drivers.
We did consider using STOP/GO or temporary signals to facilitate traffic movements, however, it was unlikely temporary signals would make any improvement except to increase the demand from Ngapipi Road (which was mostly being re-routed to Shore Road). Alternatively, drivers that would use Ngapipi Road instead joined Tamaki Drive from other access streets ahead of the intersection.

Tamaki Drive works
The partially-constructed seawall on Tamaki Drive held up during the recent stormy weather. There are still more stones to be laid before the embankment and seawall are complete.
On the road-side edge of the embankment, a wave wall to reduce waves topping over is still to come. The old kerb from this section was removed and stored away. When the embankment is complete, the old kerb will go back in.
Progress after 5 months
- Footpath work (Stage 1) completed ahead of schedule.
- Formed the foundation of the new seawall along Ngapipi Road.
- Installed new underground drainage pipes across Tamaki Drive to Ngapipi Road.
- Installed underground electric services for lighting and traffic signals.
- Environmental monitoring and compliance of the site by specialist arborists and ecologists.
When work recommences after the Christmas break on 8 January, the plan is to focus on completing the work adjacent to Ngapipi Bridge, particularly at the south-west corner. To enable this, a new road layout will be implemented from 8 January 2017 (weather permitting) until 31 January 2018.
How this will affect you and what to watch for
- We will maintain all existing traffic movements at the intersection. However, the left turn traffic from Ngapipi Road will need to give traffic on Tamaki Drive for this period.
- In late November/early December, we have made some minor re-alignment to our layout on Ngapipi Road to accommodate drainage works on the eastern side.
- After Christmas when the traffic is at its lightest, we are planning to temporarily change the left free turn from Ngapipi Road to Tamaki Drive to a give way. This is required to accommodate the work adjacent to the bridge abutment. Ngapipi Road traffic will need to give way to traffic on Tamaki Drive during this period.
- During summer, there are more pedestrians and cyclists along Tamaki Drive. Please approach the work site safely and watch out for all users at this intersection.

From 5 to 7 December 2017, we will be undertaking night drainage works.
This will include a partial road closure with stop/go signage in operation. Work hours are between 7pm and 5am. If work is delayed, it will roll to the next fine night.
There will be some light and heavy machinery noise and truck movements associated with this work and we apologise for any disruption this may cause.
Cyclists are urged to take extreme caution as temporary steel plates on the road may be slippery. These plates will be removed by the end of the week.
We are planning to do night drainage work between Sunday 26 and Tuesday 28 November (weather permitting).
This will include a partial road closure with go/stop signage in operation. Work hours are between 7pm and 5am.
If work is delayed, it will roll to the next fine night.
The seawall construction on Tamaki Drive is progressing well with over half of the embankment formed since we started the marine works in October. Our stonemasons will be on site later this week to start building the new seawall facing along Tamaki Drive using basalt stones.
We will also continue with our work along the coastal edge of Ngapipi Road including the formation of the embankment for the new shared path.
Based on our current progress, we will have the majority of the seawall completed up to the intersection before Christmas and our site office will be closed for 2 weeks between 23 December and 7 January for Christmas/New Year break.
- Road layout over the Christmas break. Based on our current progress, we will have the majority of the seawall completed up to the intersection before Christmas. Our site office will be closed for two weeks between 23 December and 7 January for Christmas/New Year break. We will maintain the current road layout over the break. While the site office will be closed for Christmas, our site traffic management supervisor will undertake regular monitoring of the site. A new road layout will be implemented from 8 January 2018 (weather permitting) until 31 January 2018.
- Questions about why the change to the road layout is done in January and if this work would be better done under the current temporary traffic layout. We have explored a number of options to undertake the work adjacent to the bridge abutment. However, there is inadequate space to accommodate two lanes of traffic towards the city and footpath; while maintaining a safe working area adjacent to the bridge. As a result, the city bound approach to the bridge will reduce to a single lane. For this to work, traffic turning out of Ngapipi Road will need to operate under a give way control. This will only be for the month of January when traffic is lightest.
- Enquiry about what the road layout will be in February 2018. We will resume the current road layout on 1 February 2018 with two citybound traffic lanes and a free left turn from Ngapipi Road.
Stage 2 works
Tamaki Drive – Ngapipi Road intersection works are running ahead of schedule. We are starting stage 2 four weeks early.
The road layout will change during stage 2 works.
Road layout changes from 26 September
Weather permitting, a new road layout will be in place from Tuesday, 26 September. It will have the same number of lanes, but these will narrow on the approach to Ngapipi Road.
The speed limit will be reduced to 30km/h and traffic delays can be expected. Please approach the intersection with care and watch out for pedestrians and cyclists.
Pedestrian and cycling facilities will also be retained, but the shared path on Tamaki Drive and footpath on Ngapipi Road will also narrow.
Ngapipi bridge widening
We want your feedback on a proposal to widen Ngapipi bridge to provide new footpaths and convert the existing footpaths into cycleways.
Feedback is open until 8 October.
Night works next week
On Sunday 17, Monday 18, and provisionally Tuesday 19 September, we will be working at night to install a new drainage pipe across Tamaki Drive.
This work is scheduled to take place at night (from 7pm to 5am) as the traffic volumes are too high during the day to do it safely.
This work is weather dependent and will be rolled to the next fine night if impacted by weather.
There will be some noise and truck movement associated with this work and we apologise for any disruption this may cause.
Work for Stage 1 is now well underway.
What we did last week
Removed existing footpath and kerb & channel along the south side of Tamaki Drive and east of Ngapipi Road.
Happening this week
- Continue footpath and kerb & channel renewal along the south side of Tamaki Drive and east of Ngapipi Road.
- Commence service installation including drainage upgrades.
Watch out for
For safety reasons, the stairs linking Paritai Drive to Tamaki Drive will be closed later this week for up to a month as we install new kerb & channel and footpath at the corner. Pedestrian detours are sign posted via Paritai Drive/Ngapipi Road and/or Paritia Drive/Okahu Street.
As a live construction site, the speed limit has been reduced to 30km/h and traffic delays can be expected. Please approach the intersection with care.
Stage 1 construction begins on Monday and Tuesday nights (21 and 22 August), with the removal of the traffic island at the intersection to create room for lane realignment.
The hours of work are 7pm to 5am, weather permitting. Traffic will be managed by stop-go signals.
There will be some associated noise and truck movement and we apologise for any disruption.
Work will start later this month on the footpath along Tamaki Drive and Ngapipi Road. Work will then begin on extending the seawall.
The upgrade should take 12 months to complete.
Read the media release: Work starting on Tamaki Drive-Ngapipi Road intersection improvements.
AT is currently in the process of engaging a suitable contractor for the intersection upgrade work.
We expect to begin construction in mid 2017.
Submissions on the resource consent application have closed.
A decision is expected in early 2017.
AT has applied to Auckland Council for the resource consent for the intersection upgrade. The consent application has been notified, which means you can make a submission.
