The Waikanae River flows from the western foothills of the Tararua Ranges about 50 kilometres north of Wellington. The upper catchment covers 125 square kilometres of predominately regenerating native bush, mature forest and pasture.
The Waikanae River meanders through a diverse landscape which has changed significantly over the years. On the upper plain near the ranges, the river's course cuts through alluvial gravels deposited by the river, before moving down through coastal sand dunes between Waikanae and Paraparaumu, to the sea.
The Waikanae River is one of the distinctive natural features of the area and is highly valued by the local community. However, as well as being a great asset, there are times when the river floods, causing considerable damage and cost to the community. A major flood in the Waikanae River could cause millions of dollars worth of damage to property and community assets.
Waikanae Floodplain Management Plan, which is the result of work done by the Waikanae River Communities, Ati Awa ki Whakatongotai, Regional Council, and the Kāpiti Coast District Council, provides a blueprint for managing the river and the floodplain over the next 40 years. It is a living document, which means it will be changed and further developed over time.
We at the Regional Council are responsible for managing flood risks associated with the Waikanae River. The Waikanae Floodplain Management Plan sets out what we will do manage this flood risk. Our role in managing the river involves removing gravel, prevent erosion, repair and maintain stopbanks to reduce the risk of flooding.

Waikanae River Environmental Strategy, an outcome of the Waikanae Floodplain Management Plan, identifies key features of the river environment with a focus on the river corridor downstream of the Water Treatment Plant. The document is the combined effort of the Regional Council and Kāpiti Coast District Council with valuable contributions from the Department of Conservation, Ati Awa ki Whakatongotai and members of the community.
There has been significant environmental improvements in respect of restoration planting, development and enhancement of access and pathways for walking, cycling and horse riding. Many of these improvements are recommendations from an earlier version of the strategy, which have been implemented by us with Kāpiti Coast District Council and the community.
