Envirostrat Director Dr Nigel Bradly was the lead Author of New Zealand’s first Marine Spatial Plan, in the Hauraki Gulf. Sea Change was a collaboratively developed initiative with representation from environmental groups, the community, commercial sectors and Māori. Sea Change had a focus on spatial and strategic prioritisation for commercial fishing, new marine protected areas, water quality improvements, ‘blue infrastructure’ and growth of aquaculture. Key to its success was the integration across different levels of government (national and regional), across the land / sea interface, and across different economic sectors. The implementation pathways include regulatory reform, impact investment in key sectors, and empowerment of local community and tribal groups.
