The Penlink Project proposes a second access route to Whangaparaoa Peninsula through a direct link between Stanmore Bay and the Northern Motorway (at Redvale).

Project overview

Current Status

Penlink2014Penlink is a new 7km arterial link proposed between State Highway 1 (SH1) and Whangaparaoa Road. This road will relieve traffic on Whangaparaoa Road and the Hibiscus Coast Highway and improve travel times and journey reliability in the area. Improved connections will facilitate planned growth (e.g. in Whangaparaoa and Silverdale) and support economic activity (e.g. Dairy Flat and Silverdale).

The Penlink alignment is already provided for in the District Plan (e.g. it is designated and there are resource consents for the operation of the road). However, new consents are needed to enable and manage construction and Auckland Transport has identified that some changes are needed.

Auckland Transport is now progressing the Penlink design and undertaking further environmental investigations to support new resource consent applications. At the same time, Auckland Transport is looking at some improvements, to provide for:

  • an arterial road with up to two lanes in each direction;
  • a grade-separated interchange (with city bound ramps) to SH1, that provides for the future development at Dairy Flat and accommodates the extension of the northern busway, as well as providing a connection to East Coast Road;
  • safety improvements for the local road connections at Weiti Station / Weiti Forest Park and at at Duck Creek Road;
  • a signalised intersection with Whangaparaoa Road; and
  • cycle facilities along the route, including a separate shared path across Weiti Bridge (Stillwater to Whangaparaoa).

AT and its consultants will be on site between March and July 2014, undertaking environment investigations for the alignment.

Following this investigation work, Auckland Transport will identify and talk to people who may be affected by the design improvements. 

Strategic importance

Auckland Plan

The Auckland Plan sets the 30 year blueprint for transforming Auckland into the world’s most liveable city. Chapter 13 focusses on Auckland’s Transport. Map 13.1 shows Penlink as part of the strategic regional transport network and map 13.2 identifies Penlink as a Priority Transport Project.

Hibiscus and Bays Local Board Plan

In 2011 the Hibiscus and Bays Local Board prepared the Local Board plan . In this plan the board identified advocating for the project as a key priority and commented that:
“A permanent alternative solution to Whangaparaoa Peninsula is vital. The Local board believes the solution is Penlink, a bridge across the Weiti River and a road connection to divert traffic to and from State Highway 1 to Whangaparaoa Road. The community supports this project and the ongoing delay in obtaining a firm commitment to construct Penlink continues to add to congestion and travel time.” (pp31).

Hibiscus and Bays Draft Area Plan

In drafting the area plan in 2012 the local board and Auckland Council identified completion of Penlink as one of six key moves to support the Auckland Plan transformational shifts. In the 10 year prioritisation schedule the plan identifies Penlink planning and funding as a priority project.

Project objectives

Auckland Transport has identified the following objectives for the Project:

  • To improve network performance to facilitate economic activity and planned growth in Silverdale and the Whangaparaoa Peninsula and the surrounding area.
  • To improve travel times and journey reliability through the ‘Study Area’ (being the land areas east of SH1 in the vicinity of the Hibiscus Coast Highway and Whangaparaoa Road: Silverdale, Millwater, Weiti, Stillwater and the Whangaparaoa Peninsula).
  • To improve network resilience for the Whangaparaoa Peninsula community.
  • To improve opportunities for mode choice in the areas serviced by Penlink.
  • To enhance integration of the transport system with adjacent land uses.


Our current work is scheduled to the following:

  • Design and Investigations will continue through to March – June 2014
  • Stakeholder and Landowner conversations and input (April – June 2014)
  • Lodgement of applications for consents / approvals on the Project (approx. mid 2014)
  • Notification/Submission period (3rd Quarter 2014)
  • Hearings (Late 2014)


Penlink Background (2001-2013)
Penlink is a legacy project developed by Rodney District Council (RDC) over 15 years ago. The Project provides a link between SH1 to the west (near Redvale) and the Whangaparaoa Peninsula in the east. Since 1996, a substantial amount of work has been completed including design, designation, consenting and development of a toll strategy.

Investigations first commenced in the 1970’s and following environmental assessment work in 1998 the original scheme (Base Design) was designated and consented in 2001 as a 7km standard arterial road connection with:

  • Two lanes (single lane in each direction).
  • A 540m bridge over the Weiti River. The bridge provided for up to three lanes (it provided for a peak flow tidal lane), with a public walkway/cycleway on one side of the Bridge.
  • A new roundabout or signalised intersection where it meets Whangaparaoa Road. Widening of Whangaparaoa Road between Brightside Road and Arklow Lane. 
  • Land purchase for the existing designation was completed in 2007 however due to funding and programming issues, the design and construction of Penlink was not progressed.


Why hasn’t construction started yet?

  • As part of the RDC work, Penlink has been designated since 2001, with land purchases largely completed in 2007. However detailed design and construction of Penlink did not occur due to issues with funding and programming.
  • Penlink has a high capital cost, and under a traditional delivery model (contract awarded for design, followed by contract awarded for construction), Penlink could be constructed in a 3 year period. However due to the value of Penlink, this would reduce the ability for other projects to be implemented as part of the Capital Programme. 
  • Investigation work has been undertaken to determine if Penlink can be tolled to provide an additional revenue stream to offset a portion of the total project cost.

What is a PPP?

  • A Public Private Partnership or PPP is a long term contract for the delivery of a public service, where the provision of the service requires the construction of a new asset such as a road as would be the case for PenLink. A PPP is privately financed however full legal ownership is retained by the public sector. .
  • For projects with certain characteristics procurement using a PPP is able to deliver best value for money by incentivising the private sector to provide innovation, more efficient risk allocation and management, and long term performance measures against specific outcomes.

Will Penlink be delivered as a PPP?

  • Current investigations indicate that procurement using a PPP could provide good value for money for the Penlink project
  • However a decision on whether Penlink will be procured using PPP has not been made as there are many factors that need to be taken into account.
  • While the PPP model is well established around the world it is relatively new in NZ (examples include Transmission Gully, Wellington, Hobsonville Schools and Wiri Prison, Auckland).
  • Further work and investigations are required before we can confirm how Penlink will be procured and delivered.

Why are you seeking an alteration to the designation and obtain new resource consents?

  • In the early 2000’s a designation corridor and resource consents were approved for Penlink (Base Design). 
  • Recently the design of Penlink has been reviewed to take into account changes in government policies, Auckland Council strategies (including the 30 year Auckland Plan) and land use intensification in and around Silverdale.
  • To respond to these changes the design is proposed to change from a 2 lane to a 4 lane road and for tolling to be allowed. 
  • The design also provides an opportunity to include provision for cycling along the entire Penlink corridor.
  • While the base design has already been approved the change from 2 to 4 lanes needs to be assessed and consents for the effects of construction activities needs to be re-applied for.

Whats the difference between the base design and the proposed design?

  • See details above, but basically the base design was a 2 lane road with a 3 lane bridge, with provisions for pedestrians and cyclists in the vicinity of the bridge. Tolling was not allowed and local road connections included right turns across Penlink.
  • The preferred design is a 4 lane toll road, with a 4 lane bridge, but also catering for cyclists along the full length. Grade separated connections are being designed to improve safety and avoid motorists needing to turn right across traffic lanes.
  • The interchange at SH1 is being designed to provide for the potential future growth in the Dairy Flat area and to accommodate the future extension of the northern busway alongside SH1.

Will you need to buy more land?

  • Land purchases for the existing designated route have been completed. .
  • As part of the preferred design review, our priority is to keep within this existing designation. Therefore no further land purchases from private properties are proposed at this stage.
  • However, there may be the possibility that additional land take will be required to enable innovative design solutions during a PPP process or to meet changed standards since the designed was approved in 2001. If this is the case, we will get in touch with the affected land owner and discuss the proposal, impacts and how we can mitigate any concerns.

My land was designated by RDC but no land purchase has occurred.

  • As part of the existing designation, RDC undertook to purchase all the land required for Penlink. 
  • This was largely completed in 2007, however some land owners at the time received letters from RDC stating that their designated land was no longer required.
  • We are aware that some of these properties still have a designation placed across them.
  • As part of the alteration to the designation we will look to rationalise the designation footprint and ensure that we identify only the land areas required for Penlink.
  • If your property is falls into this category please contact the project team and we will look to provide you with some certainty around the designation.

How will my property be affected?

  • AT and our Consultants are investigating the additional benefits and impacts of the improved Penlink design compared to the Base Case. 
  • Following this work we will have a better idea on which parties or properties may be impacted and to what extent.
  • Once this is understood we will engage with parties affected.

When will construction start?

  • At this stage the priority and programming of Penlink has not been confirmed.
  • We will outline a spectrum of engagement methods and outline how we will categorise stakeholders into these spectrums. 
  • Communication and engagement will be undertaken throughout this planning phase and further information will be provided outlining proposed open days, workshops, etc.
  • In the mean-time please feel free to contract the Penlink team if you have any immediate concerns or queries.
