ABOUT US
Forging paths through complexity
Who we are
Onepointfive is a climate advisory firm built on a simple premise: climate and nature risks are complicated, but the solutions don’t have to be — provided the groundwork is done well.
We’re a multidisciplinary team working with corporates, public sector organisations, NGOs, iwi/Māori entities and community groups on the points where climate risk and transition pressures collide with strategy, governance, policy, investment and day-to-day operations. Our work is grounded in technical rigour and delivery discipline — we build on what you already have, rather than reinventing it.
We believe the best outcomes come from embedding climate into existing systems, not running one-off projects that fade once a report is delivered. We design tools, processes and frameworks that fit your governance, risk, finance and planning machinery, and we make them transparent so your team can use and maintain them without ongoing consultant support.
Our core expertise spans climate, law, policy, risk, finance, energy security, and data, with over a decade of hands-on experience in climate change. That breadth, combined in a single integrated team, lets us see the full picture, join up disciplines and design solutions that are coherent, defensible and fit for purpose.

Our directors
Leading onepointfive's strategic direction and overseeing delivery of all client engagements across sectors.
