A survey, assessing the ecological benefits and economic costs associated with changes in braided river management
including Marlborough’s Wairau River, is underway.
This research is being conducted by Lincoln University’s Agribusiness and Economics Research Unit to look at a range of
management options that could be introduced to help protect the health of braided rivers.
A better understanding of how braided rivers such as the Wairau interact with groundwater systems is the focus of the
Gravel Bed Rivers (GBR) National Research Project, now in its fourth year. The study, funded by the MBIE Endeavour Fund
with contributions from Marlborough District Council, Hawke’s Bay Regional Council and Environment Canterbury, is
looking at three rivers - the Wairau, the Ngaruroro in Hawke’s Bay and the Selwyn/Waikirikiri in mid-Canterbury.
The voluntary questionnaire takes about 10-15 minutes. Responses are needed to ensure the survey represents the views of
most New Zealanders.

The questionnaire is anonymous. The research has been reviewed and approved by the Lincoln University Human Ethics
Committee. The results will be presented as part of the wrap-up of the Gravel Bed Rivers project in mid-2024 at a
workshop in Blenheim including Marlborough District Councillors.
