Technical review of the Overseer model

Find out about the review and the members of the panel doing the work.

Overseer review part of wider efforts to improve tools

A technical review of the Overseer model began in early 2020. Eight independent experts were appointed to a panel to do the review. The review is a major part of wider efforts by the Ministry for Primary Industries (MPI) and the Ministry for the Environment to improve decision-making tools used by farmers and growers.

Two parts to the Overseer review

The review consists of 2 parts.

The first will assess Overseer’s modelling approach for use in decision-making by farmers and growers and as a regulatory tool.

If the panel thinks that Overseer is suitable, it will also identify other aspects that should be reviewed in more depth. This part should be complete by late 2020.

The review’s second part is dependent on the earlier findings and would potentially take another year.

Members of the Overseer technical review panel

The 8 panel members were selected after a rigorous process involving the Prime Minister’s chief science adviser and the chief scientists from MPI and the Ministry for the Environment.
