I posted on this in June 2025 when it was reported in the old AgResearch website. Hopefully we can find out more about the back story to this project and the ongoing monitoring plans.

“A long-term evaluation of biochar incorporation into the soil is required to fully understand the impacts of this practice on C sequestration and any additional co-benefits. A life-cycle assessment approach could contribute to a better understanding of the overall cost–benefit of biochar incorporation in New Zealand farming systems, including biochar generation, transport, application, pasture and animal production, and environmental benefits.“
