On Monday, we begin our urgent hearing in the Wellington High Court, where we will be challenging the Minister for Oceans and Fisheries’ emergency set-net fishing closure. Why? We argue that the closure is inadequate to protect the critically endangered northern hoiho population.

For those following global surface temperature anomalies, October 2025 is going to finish 1.50C above the pre-industrial baseline and 3rd hottest on record since 1940. Which also means that October, 2025, is likely the 3rd hottest October in the last 120,000 years.
