He moemoeā mō Ahuriri: A vision plan and health assessment for the Ahuriri Estuary
The Ahuriri or Napier Estuary is of significant value to both tangata whenua and the Hawke’s Bay community as a whole. Historical and current environmental pressures, together with some questionable management processes over the years, had caused an almost total cultural disconnection between the tangata whenua and the estuary.
The project, led by Dr James Ataria, aimed to assess the situation by identifying the problem, effect and extent of the estuary’s contaminant levels. A key contributor is stormwater run-off into the estuary; essentially water flowing over roads and roofs collecting toxins, which then flows or is discharged, untreated into the estuary.
Low levels of contaminants normally associated with stormwater were measured in the sediment and the edible flesh of cockles and yellowbelly flounders. Samples collected from the Napier Estuary were compared with those of flounder caught in the Pōrangahau Estuary, the largest and least-disturbed estuarine environment on the east coast south of the Bay of Plenty. Jamie says even though he knew the drains into the Napier Estuary were close to factories and industry, he was still surprised at the high levels of contaminants at one site sampled in the estuary.
The team also carried out a literature review of historical and culturally significant events and issues using information from the Waitangi Tribunal WAI 55 Report, the courts and other significant historical records and publications.
The study involved local tangata whenua from the outset. The research team interviewed hapū representatives about their aspirations for the estuary; a senior Māori student from Napier Girls High School was part of the research team; and other school students visited the site. All of the gathered information provided the foundation for the 25-Year Living Document – a collection of tangata whenua and other organisations’ aspirations for the future of Te Whanganui-a-Orotū (the greater area which includes Napier Estuary) written by the team.
NPM’s support for this characterisation study was instrumental in allowing the researchers to successfully secure funding from the Ministry of Science and Innovation to carry out further biophysical research in the estuary and to develop an online tool aimed at enabling greater Māori participation in natural resource management via an increased awareness and access to relevant environmental planning documents.

Influences on regional policy development
• The research funded by Ngā Pae o Te Māramatanga provided Tangata Whenua with statistical and scientific data to enable them to contribute effectively to the development of emerging regional storm water policy. Hawke’s Bay Regional Council, territorial authorities and Māori are currently in the process of drafting new storm water policies, which will eventually be included in the operative Regional Resource Management Plan and the proposed Regional Coastal Environment Plan by way of plan change and variation.
• The suite of Environmental data accumulated by Māori and their research partners from the project identified a number of key issues and, along with the Regional Council’s species and State of the Environment monitoring, will provide a broad picture of the current state of the estuary, and identify the steps necessary to enhance ecological values of the Napier Estuary, and other Estuarine environments region-wide.
