Description of Waikanae River
The headwaters of Waikanae River are at Kapakapanui in the Tararua Forest Park, an area of native forest and alpine vegetation. The river travels west downstream for about 25 km before reaching the sea at the Kāpiti Coast.
In the mid-section, Waikanae River goes through areas of regenerating bush, plantation forest, small farms and lifestyle blocks. In its lower reaches there is significant urban development close to the river at Paraparaumu and Waikanae.
After passing though sand dunes and Waikanae Estuary Scientific Reserve, the river ends at Kapiti Marine Reserve. Beyond is Kapiti Island Nature Reserve, a pest-free sanctuary. Waikanae Estuary is a regionally significant area for bird habitat and fish spawning.
The river is a taonga (treasure) for mana whenua Ātiawa ki Whakarongotai, who have a kaitiakitanga (guardianship, management) plan setting out a set of kaupapa and huanga (values and objectives) for the river.
Values and demands on the river
The river provides drinking water for the Waikanae community. A river recharge scheme supplements water taken from it during times of peak demand and times of low water flows. The river is also highly valued for recreation, including walking and whitebait fishing.
Most of the catchment is in good condition, with clean water and diverse native fish species present, but these values decline in the lower reaches due to loss of fish habitat and river works.
The river is affected by demands from the communities in nearby urban areas. These include a wastewater treatment plant that discharges into the Mazengarb Stream and the Waikanae Estuary, along with stormwater. Works to help with flooding and erosion issues (gravel removal and stopbank management) have also been carried out in recent years.
About Waikanae ki Uta ki Tai
The project is being developed in a ‘Treaty house’ partnership with Ātiawa ki Whakarongotai as the ‘iwi house’ and with DOC, Greater Wellington Regional Council and Kāpiti Coast District Council aligning their roles as the ‘kawanatanga (government) house’.
The Waikanae community has representatives on the project governance group and steering committee. Collaboration with the community began in 2019. Under the terms of reference established by the governance group, the steering committee is tasked with developing an action plan for the project, in collaboration with the community.
Waikanae catchment restoration work
Restoration work in the catchment has been carried out by community groups for many years – this is one of the reasons the river was selected as a Ngā Awa catchment. The project fulfils a longstanding Waikanae community aim to coordinate the work of these groups and provide a broader ‘mountains to sea’ approach to restoration in the whole catchment.
Jobs for Nature funding
In November 2020, Waikanae ki Uta ki Tai partners received $8.5 million of Jobs for Nature funding for river restoration. Over four years, Waikanae Jobs for Nature will boost funding for unemployed people in Waikanae and build on the kaupapa of Waikanae ki Uta ki Tai.
This new funding will enable employment for riverside fencing and planting, animal and weed control and sustainable land management, as well as community engagement, education and capacity building.
LEARNZ field trip resources
In July 2020, LEARNZ took a field trip to the Waikanae River and spoke to some of the people involved in the restoration work.
