This plan is a roadmap to restore the cultural and ecological health of Whakaraupo/Lyttelton Harbour and its hinterlands as mahinga kai, now and for future generations.

The plan was put together by Christchurch City Council, Environment Canterbury, Te Hapū o Ngāti Wheke, Te Rūnanga o Ngāi Tahu and Lyttelton Port Company in consultation with the harbour communities.

Whaka-Ora Healthy HarbourIt sets out practical actions so that everyone can play a part in restoring the health of Whakaraupo/Lyttelton Harbour to mahinga kai.

These actions include addressing issues such as pollution of waterways, erosion and sedimentation, as well as improving the biodiversity of native land and marine species to ensure a better future for our harbour.

Whakaraupō Road Cutting Trial

A trial is under way to see if roadside plantings can help reduce the amount of sediment ending up in Lyttelton Harbour.

The Whakaraupō Road Cutting Trial is looking at ways to lessen the amount of sediment reaching the harbour’s waterways because it’s having a negative impact on the health of the harbour. Read more on Newsline.(external link)

During the past six months, the team have been trialing different ways of using plants to cover exposed soil beside roads around Port Hills and Banks Peninsula. Six species of native plant were selected based on their ability to cope with the harsh conditions of life by the roadside.

The project is a collaboration between Christchurch City Council and Environment Canterbury with technical input from EOS Ecology and Landcare Research.


Lyttelton Harbour wastewater scheme

The Lyttelton Harbour wastewater project will connect the harbour's wastewater to the main Christchurch system.

The Lyttelton Harbour wastewater project will connect the harbour's wastewater to the main Christchurch system. To do this, we're converting treatment plants and building pump stations around Lyttelton Harbour and installing a wastewater pipeline through the Heathcote Valley.

Lyttelton Harbour Port

Currently, the harbour's wastewater is fully treated at wastewater treatment plants in each of the townships before being discharged through outfall pipelines into Lyttleton Harbour.

The Lyttelton Harbour wastewater project(external link) will end the routine discharge of treated wastewater into the harbour, an important environmental milestone for our city.
