Mahurangi Land
Restoration Programme



Contact the Mahurangi Land Restoration Programme team now at the link below for more information and to ensure

you do not miss this fast approaching deadline.


The Mahurangi River and surrounding waterways have been a symbolic feature in the lives of Warkworth locals and surrounding areas for generations.

It's no secret that the life of this river has degraded over time and many have worked, and continue to work, hard to help restore the mauri of this precious resource to its former health. 

Mahurangi Land Restoration Programme (MLRP) is a $5 million, a 5-year long sediment reduction programme to restore the health of the Mahurangi Harbour. Auckland Council and Ngāti Manuhiri Settlement Trust have partnered to design and deliver the programme, which is funded by the 'Jobs for Nature’ Ministry for the Environment's (MfE) fund. 

The programme supports the vision, values and mahi from previous foundational projects, notably the community-led Mahurangi Action Plan; and strives to work in with ongoing community initiatives with the hope that locals will tell stories of life in the river for generations to come.


Auckland Council and Ngāti Manuhiri Settlement Trust are designing and delivering the project in partnership. Our goal is to reduce the amount of sediment reaching waterways in the catchment.

What's the problem with sediment?

Sediment is ranked the third-highest threat to marine habitats in New Zealand and it is estimated that 21,000 tonnes is lost every year from the Mahurangi catchment. 
Eroded soil ends up in our estuaries and harbours where it can accumulate and cause a decline in water quality, aquatic life and biodiversity of the entire area. 

Human activities such as urban development, roading and agriculture can speed up the process of erosion, causing more sediment loss into our rivers and streams.

Sophie Tweddle,
Planting Co-ordinator

MLRP focuses on four areas of human activity causing sediment loss: small construction sites, forestry areas, rural land use and unsealed roads.

Small construction sites

We'll expand Auckland Council's existing programme, Closing the Gap, to reduce pollution from construction activities. The more that these construction sites are compliant with existing regulations, the better we can safeguard our waterways from the pressures of developments.


We'll do this by increasing the number of monitoring specialists in the area to evaluate small construction sites and provide technical assistance to builders.

Rural land use

We'll provide funding and support to help local landowners protect areas of sediment loss on their properties. We'll also support community restoration projects on public land.


To ensure we are targeting the right areas, we're carrying out ongoing studies to monitor sediment lost from rural areas. 


We'll work alongside landowners of forestry areas, enabling them to play a more significant role in preventing erosion events before they happen.


We'll do this by building a network of landowners interested in harvesting timber and providing them with critical materials on low impact harvesting techniques and regulatory requirements.


Support will also be provided to address post-harvest opportunities, whether it’s replanting for future harvests or restoring the landscape with native vegetation.

Unsealed roads

We'll pilot 'Environmentally Sensitive Maintenance' techniques designed to reduce sediment loss from dirt and gravel roads. These techniques will also extend the lifetime of these roads.

This approach has environmental, economic, and connectivity-related benefits.
