Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): DOC (Department of Conservation) on the marine reserve, the websites of Dive Now (Sep 2026), Dive! Tutukaka and Global Dive, Divernet (Dec 2020), Seafriends (2007) on Taravana Cave, Ian Skipworth's underwater galleries (2008, 2013) for depths and Healthpoint on the chamber. No site has a published pin. These are boat dives into sea caves and arches with daylight in reach; Taravana and Isabella Cave are real caves. Certification and configurations are estimates.
