Murray Gibertson
Murray's BE (Hons) amd MBA have been complimented by very successful senior executive roles in Government and Local Government entities.
With over 15 years as Managing Director at G-Group Consultancy Ltd, I focus on delivering innovative and cost-effective solutions in concrete durability, activated carbon research and application, asset management, and full-cycle project delivery.
Our expertise encompasses concrete deterioration research, hydrogel technology, and advanced field-testing, ensuring extended service life for reinforced concrete structures. Also, we are committed to supporting bioresearch and commercialisation in production, application and problem- farming, food production and contaminant adsorption.
G-Group leverages forward-thinking strategies and a results-driven approach to address complex challenges in infrastructure and asset management. By prioritizing smart and customized solutions, our team has developed a global reputation for enhancing reinforced concrete durability and delivering sustainable outcomes for diverse projects.
As Chairman of Activated Carbon International Ltd, I lead a talented and progressive team of experienced professionals. The Team is committed to leading the way in NZ becoming a user and exporter of ‘Green’ activated carbon instead of an importer of low quality (largely coal derived) activated carbon. We have developed partnerships with a range of Iwi and national and international stakeholders who continue to add significant value to our bioresearch and technology developments.

Tony Goodman
Raised on a sheep and cattle farm in Hawke’s Bay, Tony developed a deep understanding of New Zealand’s land and farming traditions from an early age. After seven years of dairy farming, he expanded into forestry, owning and planting a 200-hectare block of Pinus radiata. In 1967, he became one of New Zealand’s pioneering kiwifruit growers, reflecting a lifelong spirit of innovation and sustainability.
Over the years, his interests and skills have ranged widely—from early radio and telephone systems to aviation, where he has owned and flown his own aircraft for more than 30 years, accumulating over 4,000 hours in the air. A passionate gardener, hunter, and agricultural producer, he has always worked at the intersection of practical know-how and forward-thinking enterprise.
For four decades, he operated his own civil engineering contracting company employing up to 100 staff and a fleet of machinery. He also founded New Zealand’s first cable television network in Paraparaumu—Saturn—which later merged into Telstra, then TelstraClear, and is now part of Vodafone.
Today, his focus is firmly on renewable energy, particularly solar heating and electricity systems. Together with his wife, Hinerangi—a trailblazing Māori broadcaster and respected Māori leader who chairs numerous trusts—they direct Te Ara Ki Matariki Ltd, a business consulting and development company.
Their current projects include designing and constructing a 41-home papakāinga (Māori village) at Te Whaiti, and advancing climate change adaptation strategies addressing food, water, energy, fire, and storm resilience for small Māori land blocks. They are also leading the revival of New Zealand’s flax industry, developing sustainable products from fibre and plant-based substrates.
A dedicated advocate for sustainable development, Tony continues to drive the creation of a domestic activated carbon production industry aimed at adding value to local resources and strengthening New Zealand’s environmental resilience.
Mark Marfell
Mark brings significant leadership experience from his role as director at Kapiti Television Ltd, where he has developed skills in overseeing company operations and strategic management. These skills are directly applicable to his role as a director at Activated Carbon International Ltd (ACIL), where strategic oversight, governance, and business development are essential.
His directorship at ACIL since April 2025, coupled with shareholder status, indicates a vested interest and commitment to the company's success. While his media background is his most public professional facet, the leadership, governance, and operational management expertise he has cultivated support his effective participation in guiding a specialized company like ACIL in the activated carbon industry.
Mark has a particular interest in renewable energy by hydro, solar and wind. The provision of renewable energy is a key component of producing green activated carbon which requires high energy input when plants commence each production cycle.
ACIL benefits from Mark's strategic planning abilities and business acumen, which help drive the company's growth, market positioning, and operational efficiencies, critical for a company in a technical and environmental sector such as green activated carbon production and distribution. This combination of governance experience and strategic oversight underpins his value as a director to ACIL
