Dr Richard Harris rose to fame after he was involved in the rescue of 12 young footballers and their coach from a Thai cave in 2018.
The Australian anesthetist helped with the delicate balance of sedating the boys so they could be extracted from where they were trapped inside the cave system.
Now retired, Richard, fellow Thai cave rescuer Craig Challen, and their team are the subject of a documentary following them on a death-defying cave dive here in Aotearoa New Zealand.
Deeper - from director Jennifer Peedom - is now screening on Netflix.
The divers have been 245 metres inside Kahurangi National Park's Pearse Resurgence, adapting technology to use hydrogen as a breathing gas and overcoming significant and life-threatening physical challenges.
