About the Shoreline Adaptation Programme

The Shoreline Adaptation Programme is planning for the future of Auckland’s 3200km of shorelines (beaches, cliffs, harbours and estuaries) in response to the impacts of climate change, erosion and flooding.

Shoreline adaptation plans

The Shoreline Adaptation Programme includes plans for 20 coastal areas across the region. We call these Shoreline Adaptation Plans (SAPs).

SAPs look at how we can manage council-owned assets and land to respond to coastal hazards and climate change over the next 100 years.

How SAPs are developed

We develop each SAP in partnership with mana whenua and guidance from infrastructure providers, technical experts and coastal communities.

Working together in this way will help guide the way we manage our coastlines and adapt to the impacts of coastal hazards and climate change into the future.

Once completed, each SAP will outline a flexible, long-term coastal management response for council-owned land and assets in its area.

Have your say on current SAP consultations

The Whatipu to South Head SAP consultation is open from 6 November 2023 until 2 April 2024.

The map explained

The map uses colours and letters to show the timeline for Shoreline Adaptation Plans by area.

2019-August 2023

Yellow - in areas W and H, SAPs were approved for:

Dark blue - in area E, a 'mini'-SAP in Waitematā Harbour West was approved for:

Yellow - in areas I and K, SAPs were approved for:

March-September 2023

Green - in areas J, P and Q, consultations are closed and SAPS are under review for:

  • Pahurehure Inlet
  • Manukau East
  • Manukau North.

The final reports for these SAPs will be available in late 2023.

  • Tāmaki River Inlet.

February-June 2024

Orange - in areas B, C and M, we are planning SAPs for:

  • Kaipara Harbour
  • Mangawhai to Leigh
  • Leigh to Algies Bay
  • Martins Bay to Silverdale.

June 2024-June 2025

Dark blue - in areas D,E,R,S,O and N, we are planning SAPs for:

  • Silverdale to Devonport
  • Waitematā Harbour West
  • Auckland Central
  • Ōrakei to Karaka Bay Beach

  • Aotea Great Barrier Island.

Shoreline adaptation plans under review

SAP consultations closed on 7 August 2023 for:

  • Pahurehure Inlet
  • Manukau North
  • Manukau East.

These SAPs are currently under review.

Stages of the Shoreline Adaptation Plan process

Each SAP includes ongoing consultation with local iwi and several months of local community engagement. This helps us to understand how communities use and value coastal areas.

Each SAP follows a process that includes:

  • local iwi review and approval
  • community engagement through public presentations and consultations
  • strategy development based on research and feedback from local iwi, infrastructure providers, Council Controlled Organisations (CCOs) and community values
  • draft and review
  • endorsement by the local board and Governing Body
  • approval.

Shoreline Adaptation Plan strategies

Each SAP applies four strategies to guide decisions around managing council-owned assets and land in its area:

  1. No active intervention: Let nature take its course without intervention.
  2. Hold the line: Defending council-owned assets and land from erosion and flooding, and preserving these areas (like walkways and sports fields) for their intended uses. We can do this by taking protective measures like building sea walls and planting dunes.
  3. Limited interventions: Allowing for some maintenance to existing coastal defences, and ensuring we keep assets safe while accepting that processes like wind, waves and storms will change the position of the coastline over time. This strategy also identifies that some assets or uses (like footpaths, sports fields and carparks) may need to be moved to manage potential risks.
  4. Managed realignment: Planning for changes to the coastline and managing risks by moving assets, uses and infrastructure away from the coast and hazard-prone areas.

Coastal Management Framework

SAPs are key to implementing the 2017 Coastal Management Framework and Te Tāuke-a-Tāwhiri: Auckland’s Climate Plan to help prepare Auckland and its coastal areas for ongoing environmental challenges.
