Mahurangi Action Plan

What is the Mahurangi Action Plan?

Launched in 2004, the Mahurangi Action Plan (MAP) is a five year community project initiated by the Auckland Regional Council (ARC) and the Rodney District Council (RDC).

It was set-up in response to long-term environmental monitoring that indicated that the health of Mahurangi Harbour was in decline. This monitoring found:

• increased sedimentation smothering marine life and causing a decline in diversity
• common shellfish no longer found in some areas, such as cockles
• boating had become more difficult because of reduced water depths.

Why is there a problem in Mahurangi?

Erosion is a natural process, but the high-levels of erosion in the Mahurangi catchment has led to increased sediment, pollutants and contaminants running into the harbour and surrounding waterways.

What is the current goal of the Mahurangi Action Plan?

To halt, slow or reverse the adverse effects of sedimentation on the Mahurangi Harbour.

How is the Mahurangi Action Plan achieving this goal?

By reducing erosion and the amount of sedimentation running into the harbour. This is achieved through a range of measures, including:

• managing projects in the area, particularly with landowners
• significant fencing and riparian planting
• compliance monitoring - earthworks, forestry
• environmental monitoring
• research and investigation including a sediment source assessment project
• extensive environmental education throughout the local community and schools.

Why do we need the Mahurangi Action Plan?

If we don't act now, the health of the Mahurangi area will continue to decline, effecting the social, economic and environment future of the community.
