State of the Environment Reporting

The reports on this page provide communities with information about the health of the region’s environment at specific points in time. These reports summarise findings from Horizons’ environmental monitoring data, science reporting, and other technical work.

These publications are required under Section 35(2A) of the Resource Management Act 1991, and aim to:

  • Enable the public and decision-makers to know what impact people have on the environment
  • Present data as useful information, enabling the evidence-based analysis, decision-making, and policy development needed for effective environmental stewardship
  • Inform communities on progress towards achieving the Council's environmental goals (e.g., One Plan targets)
  • Educate people about their local environment and actions they can take in their communities to achieve desired environmental outcomes
  • Provide accountability in terms of expenditure on Council activities
  • Support other reporting and review processes (e.g., Section 35 One Plan Chapter evaluations)
