The why!

McCallum Bros Ltd sought resource consents from Auckland Regional Council to continue large-scale off-shore sand mining in the coastal area around Mangawhai Heads in Northland.

How did we assist?

TCG supported these groups through the consent process, providing expert witnesses from both a planning and effects-management perspective, and undertook an expert assessment of biological values present at the proposed off-shore site.

What happened?

The consent was declined by the Environment Court on the basis of the evidence advanced by our clients. A series of appeal processes are ongoing; and TCG has been appointed to provide oversight and facilitate the expert panel established to review the 4-year temporary consent granted - a process that allows for matāuranga Māori and other technical expert input that will help build the knowledge base to inform future decisions around resource use in this unique marine environment.

Thoughts from our client


Working with The Catalyst Group was a game-changer for our project. Their expertise in environmental planning and their ability to balance sustainability with practical solutions was exactly what we needed. From day one, their team was proactive, insightful, and genuinely committed to achieving the best outcomes for our community and the environment. Thanks to their guidance, we navigated complex regulations with ease and delivered a project we're incredibly proud of.
