The Waikato River is arguably one of New Zealand’s most important water bodies. It has a rich cultural heritage, and embodies a number of values for all parts of society. The river has been exposed to decades of contamination, exploitation, and degradation, and its current state now paints a sorry picture. The ecological integrity has been eroded, and relationships and values held with the river have been diminished. The creation of the Waikato River Authority in 2009 brought a new era of co-management to the table regarding the management of natural resources. The Waikato River Authority implemented a vision and strategy that would guide the restoration and protection of the health and wellbeing of the river and safeguard it for future generations. This research uses sustainability assessment to assess the potential of the Waikato River Authority to reach its vision, based on the objectives, strategy and actions implemented.
