Tūhaitara Coastal Park is made up of a number of ecosystems including the fore and back dunes, exotic plantation and coastal protection plantings and the coastal freshwater network made up of a series of wetlands, a lagoon and streams which run parallel to the sea and connect the Waimakariri and Ashley Rakahuri Braided Rivers. The Trust has a 200 year plan to rehabilitate the lands to an indigenous coastal ecosystem supporting a diverse range of native flora and fauna species and providing sustainable mahinga kai.
