Arawai Kākāriki wetland restoration programme

Arawai Kākāriki is a large-scale wetland restoration programme led by the Department of Conservation.

The main goal is to protect wetlands, and increase our understanding of these productive environments. The better our understanding of these environments, the more we can improve wetland restoration in New Zealand.

An important part of the programme is getting the community involved. We are working with partners to improve our knowledge of wetland conservation issues, and building stronger relationships with iwi and regional councils.

Key sites of the programme

There is a focus on three of New Zealand's most significant wetland sites:

Our aims

We have 10 main objectives to guide our conservation work and help us achieve the best possible outcomes.

Science at our wetlands

To manage our wetlands effectively, we need to understand the ecological processes that keep these areas healthy and resilient. Currently there is limited information of some threats to wetlands and this creates a "knowing–doing" gap.

Science research is helping to fill this gap. By working together, scientists and wetland managers are able to describe sensible goals and guidelines for restoration.

Alongside monitoring, good science also shows what isn't working so we can develop more efficient and effective methods. By maintaining healthy and resilient wetlands we can protect the natural capital in wetlands, and enhance the services they are capable of providing.

Community involvement

The three wetland sites are all different in terms of management approaches, land ownership and communities of interest. Building community awareness and involvement in wetland conservation is an important component of the Arawai Kākāriki programme.

At all three sites, the community is involved in some way, and they are informed about what is happening at each site through newsletters, factsheets, meetings, events, displays and media articles.
