Deep Dive Division
Based in the Waikato, Deep Dive Division is a commercial, scientific, and robotic diving company founded in 2018 by Tua and Courtney Karalus. We’re proud to be Aotearoa’s only Māori and Pacific-owned dive company of our kind, bringing a unique and culturally grounded approach to our work.
Guided by Te Ao Māori, Pacific worldviews, and Mātauranga Māori, our practice is deeply rooted in sustainability and respect for the natural environment. We work closely with our clients to deliver meaningful outcomes that honour both the ecosystems we operate in and the cultural values that shape them.
At the heart of Deep Dive Division is a commitment to restoring balance between people and the environment. As kaitiaki (guardians), we lead through action, collaboration, and integrity—always striving to protect and preserve the spaces we work within.
Founder Tua Karalus brings over 25 years of commercial diving experience, paired with a Master’s degree in Environmental Science. This unique blend of practical expertise and academic knowledge forms the foundation of our comprehensive, culturally responsive diving and environmental solutions.
