This project is an extension of project 16006E: Scoping the value of performance of interventions across the NZ Biosecurity system.

The MPI biosecurity system faces increasing pressure from significant increases in goods and passengers, changing pathways and types of goods. With this increasing pressure, all layers of the system need to work together cost-effectively to maximise the reduction of biosecurity risk to New Zealand under sharply constrained resources.

In order to increase the efficiency of biosecurity investment and to identify opportunities for substantial improvement, the Ministry needs to determine the relative contribution of each layer towards biosecurity effectiveness. Presently, there is no agreed framework or process available to evaluate the comparative value of biosecurity activities implemented at intersecting sites across the biosecurity system matrix. Without knowledge on the likely effectiveness and costs of activities and control measures, risk management decisions on measures and allocation of resources at different “nodes” cannot be systematically evaluated.

This project seeks to further develop a decision-support framework that would significantly improve risk management decisions and resource allocation throughout the biosecurity system (from pre-border to pest management) by applying a systematic risk / return approach and evidence based analysis. The project will focus on extending current work on a high-level framework and example case studies e.g. fruit flies and brown marmorated stinkbug, to provide a much more comprehensive tool to populate with data across all major pathways.

The project objectives are an extension to those provided for project 1606E:

1. Develop a fit-for-purpose pathway-based framework using the seven layers of the NZ biosecurity system that will allow risk management decisions to be made on a risk / return basis.

2. Provide specific performance outputs for specified pests e.g. fruit fly, BMSB, and selected pathways

Comparative analyses will ultimately, after (i) the completion of this scoping project, (ii) appropriate generalization of its outcomes, and (ii) implementation of its recommendations:

  • Illustrate the value of the current allocation of biosecurity activities and resources
  • Inform and justify reallocation of resources where needed
  • Provide evidence-based information for adjustment of existing measures at specific nodes in the biosecurity system matrix
  • Support communication of the holistic and interdependent nature of the biosecurity system to all stakeholders.
