Why NZ should redraw council boundaries to match our connections to the landscape
Reshaping local boundaries based on river catchments would make for a more cohesive approach to all aspects of water management – and how communities really live.
The government of New Zealand is contemplating a significant overhaul of local government, including proposals from councils on how to establish new unitary authorities. The current system of administrative boundaries, which are often based on topographic features such as rivers and mountain ranges, raises questions about whether they accurately reflect connections to the landscape.
As part of this reform, Ngāi Tahu, the largest iwi (tribe) in the region, has submitted a plan that suggests drawing administrative boundaries to match catchments rather than cutting through them.
This approach would prioritize catchments, which are defined by natural physical features like rivers, as the basis for defining administrative boundaries. The proponents argue that this would be a more meaningful way to manage systems and communities that are already interconnected. The catchment approach would also allow for a more holistic management of water resources, as it would integrate hydrological systems (water quantity and quality) with community involvement.
The catchment-defined approach is also consistent with the national policy statement for freshwater management, which emphasizes an integrated framework for water management. This approach could also help councils meet their Treaty settlement obligations, as there is often a significant overlap between catchments and settlement areas, rohe, and takiwā (territory).
However, applying a landscape approach to administrative boundaries requires revisiting some of the current principles that inform the process. One such principle is the thalweg model, which has historically led to disputes over country borders when rivers change course. Additionally, a global study of subnational river boundaries shows that watersheds can sometimes lie entirely within one jurisdiction, suggesting potential conflicts with the thalweg model.
In conclusion, a catchment-defined approach to administrative boundaries could provide numerous benefits, including more cohesive water management, stronger cultural connections to the landscape, and better alignment with Treaty settlement obligations. This approach offers a more meaningful way to reflect connections to the landscape and provides a framework for addressing challenges posed by a changing climate, population growth, and increased demands for food production.
