Project phase: Investigation & designation
Project zone: South
Auckland Transport (AT) will upgrade the Redoubt Road - Mill Road corridor in 2 phases:
- A northern section
fromState Highway 1 at Manukau to the intersection of Mill Road and Popes Road.
- A southern section from the Mill Road/Popes Road intersection to Papakura and Drury.
The upgrade of the road corridor includes:
- A 4-lane road and upgraded intersections.
- Improved public transport infrastructure and services.
- On-road cycle lanes and shared path facilities.
- New footpaths on both sides of Redoubt and Murphys Road and safe pedestrian crossing opportunities at the Diorella/Redoubt, Hollyford/Redoubt intersections.
The project offers transport and safety benefits to both road users and the community:
- Improved transport access for Manukau, Flat Bush, Takanini, Papakura and Drury.
- Flexibility to support future growth in the area.
- More reliable bus journey times, the ability to move more people and address constraints on the public transport network.
- Improved travel times and safety for drivers, pedestrians and cyclists.
- An alternative north-south corridor in case of major disruption or emergencies on other southern arterial routes.
- Improved access to open spaces, community services and facilities.
Dates are indicative and depend on the planning process and funding approvals.
- October 2014 - Northern section: Route identified and notices of requirement lodged.
- 2015 - Northern section: Public submissions and hearing on notices of requirement.
- 2015 - Southern section: Progress work to identify a route alignment.
- 2016 - Northern section: Independent commissioners recommended the designation be confirmed subject to conditions that address environmental matters and various concerns raised by submitters.
- April 2016 - Northern section: AT confirms designation with Auckland Council.
- May 2016 - Northern section: six appeals to the Environment Court lodged.
- November 2016 - Northern section: Final appeal settled and the programme to acquire properties fully affected by the project begins.
- December 2016 - Northern section: Environment Court confirms all appeals have been resolved and the designation is now final.
- Mid 2017 - Northern section: Procurement of detailed design services.
- Late 2017 - Northern section: Negotiations for the purchase of the affected partial properties.
- Around 2020 - Northern section: Phased construction scheduled to begin along Redoubt Road, Mill Road and Murphys Road, but depending on funding availability, these works could start earlier.
- 2023 - Northern section construction expected to be completed.
Changing land use, population growth and planned housing developments are adding pressure on transport infrastructure in south Auckland:
- An estimated 10,000 new houses are fast-tracked in special housing areas in southern parts of Auckland, including 4,470 houses in Flat Bush, and 1,770 houses in Takanini.
- A further 12,000-14,000 houses are anticipated to be constructed in the Takanini, Opaheke, Drury and Karaka future urban zone under the proposed Auckland Unitary Plan.
- New industrial areas in Takanini and Drury south will create 6,000 new jobs.

AT predicts traffic volumes will increase to a level that is more than the current Redoubt and Mill Roads can cope with. Congestion is already affecting parts of Redoubt Road and Mill Road and this will double on some sections in 10 to 15 years.
There are also significant crash hot spots at junctions and curves along this route, making it necessary to improve the road. Between 2009 and 2013, 283 vehicle crashes and 4 deaths were reported.
Improvements to the Mill Road corridor are identified as a priority in the Auckland Long Term Plan (LTP).
The northern section
This part of the Mill Road project covers the northern 8.9km section of the Redoubt Road-Mill Road corridor starting at the State Highway One (SH1) on- and off-ramps on Redoubt Road running east, then south along Redoubt Road to the Redoubt Road/Mill Road intersection.
From here, the corridor continues south along Mill Road, ending south of Alfriston Road near the intersection of Mill Road and Popes Road. It also includes a short section along Hollyford Drive to the north of Redoubt Road and a portion of Murphys Road from a new intersection on Redoubt Road to Flat Bush School Road.
The northern section is currently going through the notice of requirement/designation process.
Features of the northern section of the Redoubt Road-Mill Road corridor
- Redoubt Road widened to 4 lanes (2 in each direction) between SH1 and Murphys Road.
- Westbound bus lane along Hollyford Dr and Redoubt Rd towards Manukau.
- Replacement of the existing Mill Road with a new 4-lane arterial (2 in each direction) between Murphys Road and Popes Road.
- 17m and 23m high viaducts above native bush at Puhinui Creek gully and South Mill Road gully.
- New roundabouts at Ranfurly Road and Alfriston Road with pedestrian facilities including safe crossing facilities in the medians.
- New and improved signalised intersections at Diorella Drive,
HollyfordDrive, Santa Monica Place and Murphys Road. These intersections will have pedestrian crossings and stop boxes for cyclists.
- Widening of Murphys Road to four lanes (two in each direction) between Flat Bush School Road and Redoubt Road.
- Murphys Rd-Redoubt Rd intersection realigned and traffic lights added to improve safety.
- On-road cycle lanes on both sides for the length of the upgrade.
- Off-road shared cycle and
foot pathfor the length of the upgrade.
- Widened footpaths on both sides of Redoubt Road, Mill Road and Murphys Road with pedestrian crossings at key intersections.
- Improved access to local community services and facilities such as Totara Park and Murphys Bush.
- Replacement planting and stream restoration.
- Improved stormwater facilities for the entire corridor which includes wetlands areas for stormwater treatment and retention.
- Landscaping of the new road corridor.

The design has been carefully considered so that it will accommodate the future urban and rural character of the corridor, as well as the natural and topographical landscape features.
A large number of routes were investigated and potential effects assessed before the final route was selected.
The project team propose the following conditions to reduce or avoid, remedy or mitigate any long-term impacts:
- Implementing a noise and vibration management plan.
- Managing potential soil contamination, stormwater run-off and dust.
- Undertaking replacement planting and stream restoration.
- Creating a number of wetland areas.
- A pest eradication programme.
- Monitoring environmental issues during construction including the impacts on flora and fauna in the area.
- Ongoing environmental monitoring after works
arecompleted to ensure successful implementation of environmental mitigation measures.
- The route was selected at Puhinui Creek to avoid mature forest. It crosses 2 areas of native forest via 17m and 23m high viaducts. These will be built at Puhinui Creek gully and South Mill Rd gully.
A number of recommendations have been made in the Ecological Assessment to avoid, remedy or mitigate adverse ecological effects associated with the project:
- Mitigate loss of native vegetation by planting trees and other vegetation in the designation. This will aim to increase the current extent of existing forested or scrub area. The creation of any new wetland habitat, which is scarce in the area, would be a direct benefit to local birdlife and offer ecological benefits.
- Clearance of native forest vegetation should commence outside the nesting season for most native birds.
- Consider bat behaviour and ecology during the design and construction of the road. Steps that could be taken include:
- Minimising vegetation clearance.
- Monitoring mature trees for bat habitation before
- The breeding season for long-tailed bats is generally between November and late January. Vegetation clearance would ideally avoid this period.
- Minimise road lighting. Where lights are necessary, use downward-facing low-pressure sodium lamps with hoods to limit spillage.
- A rescue and relocation programme for both native geckos and skinks. If native lizards are found in substantial numbers, habitat enhancement (refuges and food supplementation) and pest control should be undertaken around release sites for a minimum of 5 years to ensure the habitat is able to support the increased population
- Provide fish passage and appropriate stream restoration where culverts are built.
- Retain a habit linkage beneath the Puhinui Creek Gully viaduct during construction of piers which will remain after completion.
Cycling and walking improvements
- On-road cycle lanes for the length of the upgrade, varying between 1.5 and 2m wide.
- Off-road shared use paths for less confident cyclists and pedestrians on 1 side of the length of the upgrade.
- Advanced stop boxes for cyclists at intersections with traffic lights.
- 2m-wide footpath on both sides of Redoubt Road between SH1 and Hollyford Drive intersections. A mix of footpaths and the shared use path will be provided for the rest of Redoubt Road, Mill Road and Murphys Road.
- Pedestrian crossings on all legs of intersections with traffic lights (Hollyford/Redoubt, Diorella/Redoubt, Murphys/Redoubt).
- Safe crossing refuges in medians at Ranfurly Road and Alfriston Road roundabouts.
Public transport improvements
- Public transport improvements to the Mill Road Corridor will provide more frequent and more reliable public transport services. Bus priority facilities will be provided at the Hollyford Drive/Redoubt Road intersection, including a dedicated right turn lane for buses turning out of
HollyfordDrive into Redoubt Road.
- A new
west-boundbus lane is proposed between HollyfordDrive and SH1 intersection. The proposed bus lane will allow buses to travel unimpeded between HollyfordDrive and Diorella Drive, and between Diorella Drive and the motorway.
- The frequency of bus services will increase which will provide a better level of service for public transport users.
- Improvements to bus priority facilities and frequency will enable a strong integration with connector routes and local services. Bus priority facilities will be provided at the Hollyford Drive/Redoubt Road intersection, including a dedicated right turn lane for buses turning out of
HollyfordDrive into Redoubt Road.
In the southern area beyond the Mill Road/Pope Road intersection, the Supporting Growth programme (a collaboration between Auckland Council, Auckland Transport and the NZ Transport Agency) will focus on upgrading the Mill Road corridor from Manukau and Flat Bush to Papakura and Drury.
This will help improve safety, provide greater access to new growth areas and provide an additional north-south route. It will link to State Highway 1 and add to a new expressway between Drury, Paerata and Pukekohe.
AT has directly contacted landowners affected by the project and is meeting with them.
If your property is affected, AT will:
- work with you to manage your concerns.
- explain the support you are entitled to.
- explain the relevant processes and your rights.
What happens to affected properties
The purchasing programme is already well underway. Auckland Transport has already acquired some of the properties needed for this project and is in contact with people who own properties that are either entirely or partially required.
Property owners directly affected by the Redoubt Road-Mill Road upgrade will be fully and fairly compensated as AT buys the land required for these works. AT is required to ensure any compensation is negotiated fairly in the interests of both ratepayers and affected
We understand that selling your property can be a difficult time for some landowners, while for others, getting some clarity around possible options and timeframes may help to allay any unnecessary stress and concerns.
Selling to Auckland Transport is different from selling on the real estate market in that:
- You pay no real estate agent's commission.
- AT pay reasonable legal fees.
- In some cases, AT pays moving costs.
- It also has the advantage of a relatively quick settlement (if desired) with monies paid into your solicitor's trust account within approximately three weeks of acceptance or at a time agreed by both parties.
Following feedback from some property owners to date, AT offers:
- Flexible settlement terms of up to six months; and/or
- the option of renting the property back on a periodic tenancy to give you further time to find alternative accommodation.
Full property acquisitions are well underway, and partial property purchases began in early 2017. If you own a property that is in the designed project zone and
The detailed design works phase is about to begin.
If you have questions relating to property purchases or queries regarding the Notice of Requirement/Designation please email: firstname.lastname@example.org or phone Daniel Ratahi on (09) 448 7243.
Processes for managing land purchases or compensation for those affected by a new road are explained in AT's guide for people affected by land purchase and compensation (PDF 253KB). Information is also available from Land Information New Zealand's website.
The Resource Management Act 1991 (RMA) allows for areas of land to be designated for use as network utilities (such as roads and telecommunications facilities) or large public works (such as schools and prisons). Once a designation is in the relevant plan (the Auckland Unitary Plan in this instance), the proposed works can be carried out there at any time, the authority responsible does not have to comply with district plan rules. Once the designation is put in place, the Requiring Authority (Auckland Transport in this case) may do anything allowed by the designation, and the usual provisions of the district plan do not apply to the designated site. The Requiring Authority will still need to get any resource consents required from the regional council.
A designation restricts anyone other than the Requiring Authority (Auckland Transport in this case) from carrying out work on the designated land that will prevent or hinder the project or work to which the designation relates, without first obtaining the requiring authority's permission.
