This presentation will outline the regulatory framework for biosecurity programmes within the Rotorua Lakes and explore a range of potential options for tackling the framework, drawing on my experiences with collaborative comprehensive consenting and national policy tools. Examples to be discussed will include: · National aquatic weed consent. A multi-agency reassessment that has expanded the aquatic weed toolkit under HSNO and provided efficiencies through reducing administration costs. · Comprehensive consenting in the Waikato region. Programme level consents for the Waikato Regional Council, their effectiveness, outcomes and relevance to the Rotorua Lakes context. These examples showcase a range of alternative responses to regulatory requirements that have resulted in positive outcomes for the agencies involved and could provide a framework for the Rotorua Lakes programmes.
