Boffa Miskell landscape architects and ecologists assisted Te Taumutu Rūnanga with developing a feasibility study based on an existing concept plan. This included:

• Confirming available water resources and what size wetland the site could support.
• A study of potential mahinga kai, recreational and ecological values informed by current site conditions, and the whakapapa and mātauranga māori held by Te Taumutu Rūnanga.
• Review of potential water quality enhancement options and likely operational requirements. 

The feasibility study produced a refined wetland design based around three ponds connected by shallower planted channels. Watercress beds, macrophyte cover, rock riffles, salvaged logs, and tree root balls, along with boulders in and around the ponds, were included to provide diverse habitat opportunities.

A track around the wetland provides easy access for visitors and maintenance with stopping points to encourage mahinga kai, and recreational and educational exploration.

Extensive native terrestrial and aquatic planting sought to enhance local biodiversity and ecological functionality of Papatahora Stream whilst creating a variety of aquatic environments that support a range of mahinga kai species and values. Whilst not the primary goal, the design considers how to achieve maximum water treatment capacity within the available land area and site constraints.

A pro-bono water monitoring program was implemented help build a better understanding of the site’s hydrology.
