Penlink is a proposed alternative route between the Whangaparaoa Peninsula and State Highway 1 (SH1) at Redvale.

Project status: Design
Project zone: North

Project overview

The Penlink proposal includes:

  • 7km of new road, including a new bridge across Weiti River.
  • Four lane toll road (two in each direction).
  • Provisions for pedestrians and cyclists.
  • 100km/hr speed limit.
  • Historic Rodney District Council project; Weiti Crossing was first identified in 1980s.


  • Improved travel times and journey reliability:
    • 5 minute saving for commuters using old route,
    • 12-18 minutes savings for commuters using toll road,
  • 5.8km shorter route,
  • Contributes to central government and Auckland strategic policies and plans, and the Hibiscus and Bays area plan in terms of:
    • Value for money,
    • Safety,
    • Integration between land use and transport,
    • Efficiency and effectiveness of the transport system,
    • Economic growth and productivity.
  • Improved network performance to facilitate economic activity,

  • Improved network resilience,

  • Improved mode choice,

  • Enhanced land use - transport integration.


2013 - Project reviewed in response to planned future growth; business case confirmed.
2014 - Designation alteration and re-consenting (for construction works) commenced. Key stakeholders consulted based on a revised four-lane. link. Assessment of environmental effects undertaken.
2015 - Statutory process for the alteration to designation and resource consents will commence.

Project details

Penlink is a new 7km arterial link proposed between SH1 and Whangaparaoa Road.

The project has three key objectives:

  1. Improve travel times and reliability.
  2. Improve network performance and resilience.
  3. Facilitate economic activity, planned growth and transport mode choice.

Penlink map The new road will relieve traffic congestion on Whangaparaoa Road and the Hibiscus Coast Highway and improve travel times and journey reliability in the area. Improved connections will facilitate planned growth in Whangaparaoa and Silverdale and support economic activity, eg. in Dairy Flat and Silverdale.

The Penlink alignment is already provided for in the District Plan (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 AT has identified some necessary changes to the project:

  • Increase capacity of Penlink from a two-lane to a four-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.

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 public engagement will need to be completed before a toll can be implemented.

Next steps

For construction of Penlink to commence, the Resource Management processes must be completed and funding needs to be approved and prioritised in the Regional Land Transport Plan (RLTP).

Auckland Council has publicly notified the Notice of Requirement for an Alteration to Designation 167 – Weiti Crossing (Penlink) and submissions are open until 2 April 2015. Submissions were reviewed and a Council hearing held from 22 - 24 September 2015.

Key facts

  • Designation approved in 2001, based on a two-lane road.
  • Land purchases completed in 2007.
  • Project handed over to Auckland Transport in 2010; current Land Transport Plan shows design funding in 2018 with construction starting in 2021.
  • 2013 review of specimen design and growth assumptions.
  • Direct consultation undertaken with Mana Whenua. Te Kawerau a Maki and Ngati Manuhiri prepared a joint cultural impact assessment.
