Tū Mai Taonga has produced a 2023 Impact Report to highlight the continued progress of the project since the end of 2022. Anchored in the Tikanga of Ngāti Rehua Ngātiwai ki Aotea, the project has commenced operations on the pathway to the eradication of feral cats and rats across Aotea.

Feasibility Study
In November 2021, Kurahaupo Consulting prepared a summary of the rationale for pest
management on Aotea developed by the Aotea Great Barrier Environmental Trust as a proposal for Jobs for Nature funding.
It provides a formal study of what is feasible in relation to feral cat and rat eradication or control given the current and potential tools and constraints of their use and offers background details on how the project might be implemented.

A Pathway to Eradication
Following the review of the Kurahaupo Consulting feasibility study by the Tū Mai Taonga Technical Advisory Group and the project’s funders, a Pathway to Eradication was defined. This longer-term, adaptive approach to realising a predator-free future for Aotea helped the project secure commitments from funders and is guiding operational planning.
