Senior finance, climate and energy ministers from Australia and New Zealand met in Auckland on 5 December for the third Climate and Finance Ministers’ 2+2 Dialogue, using the session to underline affordability, reliability and economic resilience as the core drivers of their climate cooperation.
Ministers stressed that “climate action and more investment in renewable energy are essential to putting downward pressure on power prices and cost of living for New Zealand and Australian households and businesses and enhancing the productivity, security and stability of our respective energy systems.” They argued that the shift toward lower-emissions economies is creating “significant economic opportunities” for both countries.
A central feature of the discussions was a push to simplify regulations across the Tasman. The ministers agreed to “continue to align regulatory frameworks, reduce barriers to investments, and ensure sustainable finance systems are interoperable,” framing these steps as a way to avoid unnecessary compliance costs.
Both governments will co-invest in upgrading the Equipment Energy Efficiency (E3) Program registration system, with New Zealand committing around NZ$1 million and Australia around AU$4.1 million. According to the joint statement, the update aims at “reducing compliance burden and accelerating the adoption of energy efficient products.”
Further work will target consistent rules for smart-function EV chargers, joint Vehicle-to-Grid standards, and closer contact between solar and battery industries and regulators on each side of the Tasman.
Ministers noted progress on aviation fuel collaboration, highlighting Bioenergy Australia’s work on a trans-Tasman Sustainable Aviation Fuel strategy. New Zealand also “welcomed the announcement of Australia’s $1.1 billion Cleaner Fuels Program.”
Both sides underlined the value of “clear net zero plans and internationally relevant standards for attracting investment,” and reaffirmed alignment on sustainable finance taxonomies and Guarantee of Origin certification, including Australia’s scheme launched in November.
Agricultural emissions reductions remained a shared priority, with the statement pointing to AU$300 million invested in Australia and over NZ$400 million in New Zealand.
Economic reform programmes will continue to align, with ministers targeting lower business costs and lighter regulatory load. They also agreed to create a working group to help “ensure insurance remains accessible.”
The ministers recalled that Pacific leaders reaffirmed climate change as the “single greatest threat to the livelihoods, security, and wellbeing of peoples of the Pacific.” Both countries will co-host technical training for Pacific energy regulators in 2026.
