His travels into the Southern Ocean for whaling and fishery's protection campaigns resulted in a renewed appreciation for the ecology of New Zealand and our sub Antarctic islands. Richard returned to live in NZ in 2008 with his partner Kate and young family, and together built a modern, earth insulated eco house with renewable power system at Shag Point. Last year Richard moved back to Portobello, and is very pleased to be a part of this wonderful Otago Peninsula project as we move into the final years of the eradication plan.
