Stephanie James Senior Consultant Contact me

When the Environmental Protection Authority (EPA) proposed changes to chemical regulations, they needed to understand diverse stakeholder perspectives quickly. Our systematic analysis of 29 submissions gave them clear, actionable insights that balanced environmental protection with practical implementation.

The EPA regulates activities affecting New Zealand's environment, particularly managing hazardous substances.

When they proposed amendments to improve chemical management requirements for pesticides, fumigants, antifouling paints, timber treatment chemicals, and explosives, they faced a challenge. With 29 submissions containing responses to 31 detailed questions and limited internal resources, the EPA needed expert help to identify patterns and insights that would inform their regulatory decisions.

The analysis helped the EPA refine their proposed amendments to achieve their environmental protection goals while addressing practical implementation challenges. The EPA used our report to brief their Board and inform the next steps in their regulatory process.

Informed regulatory decision-making

While 29 submissions sounds a small number, the complexity of the submissions and the research and validation required around the evidence presented, meant this was not a simple task. 

The EPA received our comprehensive analysis within two weeks, enabling them to move forward confidently with their regulatory process. Our report provided clear answers to each consultation question, identified key stakeholder concerns and the presentation of quantitative data to support understanding of stakeholder positions.
