Statistics and Decision Support
Statistics and decision support consultancy
Southern Clarity NZ
Southern Clarity NZ is a New Zealand-based statistical modelling and decision-support consultancy helping organisations turn complex environmental and operational data into evidence for confident decisions.
What we do
We deliver end-to-end analytical solutions combining rigorous statistical modelling, reproducible workflows, and interactive decision-support tools. Our systems evolve as new data becomes available and new management questions emerge.
Statistical modelling
Build robust inferential and predictive models to understand environmental systems, quantify uncertainty, and support evidence-based management decisions.
Decision-support tools
Design interactive dashboards and scenario tools that help teams explore data, compare management options, and act faster.
Reproducible analytics
Implement transparent, auditable workflows that update as new data and management questions emerge.
Tools & methods commonly used: R · QGIS · GitHub · Docker · Bayesian and spatial modelling · Reproducible pipelines · Interactive dashboards · AI-assisted workflows
Selected work
Operational spatial dashboard
Built an interactive spatial dashboard for Trap & Trigger Ltd that integrates field activity data into a map-based interface, helping teams visualise operational coverage and manage project data in real time.
Energy system modelling for New Zealand
Developing a Bayesian modelling framework with Whirika Consulting to estimate Energy Return on Investment (EROI) across New Zealand’s energy technologies, helping support long-term planning and evidence-based energy transition decisions.
Yellow-eyed penguin population modelling
Developed a Bayesian modelling framework for the Department of Conservation to estimate hoiho breeding population size by integrating camera observations, landing-point surveys, and expert knowledge while accounting for imperfect detection.
QGIS workshop for Trap & Trigger Ltd
Built reusable mapping workflows for operational teams, including data import standards, geoprocessing patterns, and export-ready outputs to reduce repeated manual steps.
Kakī population modelling for the Department of Conservation
Developed an integrated modelling framework to support long-term planning, quantify uncertainty, and identify where management effort can have the greatest impact.
Why Southern Clarity
Clarity, rigour, and client ownership are central to every engagement.
Client ownership
You retain full ownership of your data, code, and tools.
Transparent methods
Approaches are documented, reproducible, and easy to communicate to technical and non-technical audiences.
Decision-ready outputs
Deliverables are designed to support real decisions, not just static analysis reports.
Who we are
Southern Clarity NZ was co-founded by Stefan Meyer and Anthony Davidson in 2025. The company helps organisations turn complex data into clear evidence for decision-making through rigorous statistical modelling and practical analytical tools.
Stefan Meyer brings more than nine years of consulting and project delivery experience across government, research, and industry. His work focuses on Bayesian modelling, advanced statistical analysis, and the development of reproducible analytical systems for complex monitoring and spatial data. He holds a PhD in Ecology from the University of Otago, where his research focused on statistical methods for analysing complex natural systems.
Anthony Davidson combines a background in ecology with strong quantitative and technical expertise. He holds a Master’s degree in Ecology from the University of Otago and is also a registered mathematics teacher. At Southern Clarity NZ, Anthony focuses on analytical tool development, data systems, and AI-assisted workflows.
Together, Stefan and Anthony build analytical systems that are transparent, reproducible, and designed for long-term use by the organisations that rely on them.
