Penlink Penlink

Penlink (peninsula link road) is a proposed alternative route between the Whangaparaoa Peninsula and State Highway 1 at Redvale.

Project status: Investigation & design.
Project zone: North.

Project overview

Penlink will connect Whangaparaoa Peninsula with State Highway 1 (SH1). The proposal includes:

  • 7km of new road, including a new bridge across Weiti River.
  • Four-lane toll road (2 lanes in each direction).
  • Provisions for pedestrians and cyclists.
  • 100km/h speed limit.


  • Improved travel times and journey reliability.
  • Reduced traffic congestion on Whangaparaoa Road and the Hibiscus Coast Highway.
  • Improved network performance, safety, and resilience.
  • Facilitates economic activity, planned growth, and choice of travel mode.


  • 2013 - Project reviewed in response to planned future growth; business case confirmed.
  • 2014 - Designation alteration and re-consenting (for construction works); key stakeholders consulted based on a revised 4-lane road; assessment of environmental effects.
  • 2015 - Statutory process for alteration to designation and resource consents.
  • 2016 - Designation confirmed and resource consents approved.

Project details

Penlink is 5.8km shorter that the current route and will save commuters 12-18 minutes (commuters using the old route will also save 5 minutes due to reduced traffic).

Penlink contributes to central government and Auckland strategic policies and plans, and the Hibiscus and Bays area plan in terms of:

  • Economic growth and productivity.
  • Safety.
  • Integration between land use and transport.
  • Efficiency and effectiveness of the transport system.

Penlink is one of the roading projects identified in the preferred transport networks to support new housing and business areas over the next 30 years.

Reduced traffic through the Silverdale Interchange will free up transport capacity for housing development in Wainui, Silverdale West, and approved development on the Whangaparaoa Peninsula. Improved connections will also support economic activity, eg. in Dairy Flat and Silverdale.

A toll similar to the Northern Gateway is likely to be implemented once the road has been complete. There is a separate legislative process and we will need to engage the public before a toll can be implemented.

Next steps

AT has completed the route designation and has all the necessary resource consents to progress with the project.

Current funding constraints have consigned the project to the second decade of the 30-year investment programme.


Penlink was a historic Rodney District Council project (the Weiti Crossing was first identified in 1980s).

Land purchases were completed in 2007 and the alignment was provided for in the District Plan (designation was approved in 2001 and resource consents granted based on a 2-lane road).

The project was handed over to AT in 2010. Following a review of specimen design and growth assumptions in 2013, AT identified some necessary changes to the project:

  • Increase capacity from a 2-lane to a 4-lane arterial road along the full 7 kilometres.
  • Provide a separated cycling and pedestrian shared path between Duck Creek Road and Whangaparaoa Road, including over the Weiti Bridge.
  • Provide grade-separated connections at Redvale, the Weiti developments, and Stillwater.
  • An off-ramp and acquisition of land at Redvale Interchange.
  • Alter the designation on Whangaparaoa Road for tie-ins with Penlink.
  • Acquire an additional property on Duck Creek Road to avoid effects on that property due to its proximity to the alignment.

The process to alter the route designation and change the existing operational consents began in 2015 and was completed in July 2016.

Direct consultation has also been undertaken with mana whenua. Te Kawerau a Maki and Ngati Manuhiri prepared a joint cultural impact assessment.
